Anyway, you are using that <code>Map</code> as the root of the data-model, so the keys in that <code>Map</code> are the top-level variable names in the template. So instead of <code>ftlDataMap.replyMessages</code> you should just write <code>replyMessages</code>. Also <code><#if ftlDataMap.replyMessages?size >; 0>;</code> is incorrect, a the <code>>;</code> in <code>>; 0</code> will close the tag.

They currently override the <code>isUseAdviceWith</code> method to return <code>true</code>, so that the Camel context is not started automatically and using <code>adviceWith</code> in the tests does not trigger a restart of the context. So far, so good. After upgrading to Camel 4.7.0, the <code>isUseAdviceWith</code> method is deprecated. This appears to be due to work on CAMEL-20785 and CAMEL-20843. These are good changes, FWIW :) From what I understand, the replacement for overriding <code>isUseAdviceWith</code> would be to configure <code>testConfigurationBuilder.withUseAdviceWith(true); </code> in the <code>setupResources</code> method or in a <code>@BeforeEach</code> method. My questions are: (1) do I understand that correctly? And (2) if that is the path forward, is it a mistake that <code>withUseAdviceWith</code> is currently <code>protected</code> and can therefore not be called when setting up the unit test?

This includes updating from camel-test-spring to camel-test-spring-junit5. After a couple of changes to annotations and some other things, I had a compiling build again. But the tests all fail, and the reason is that none of my @Autowired and @MockBean properties actually contain anything. They're all uninitialized. Here's a short example of what the tests look like now and what they looked like before. Now (injection not working): <code>@CamelSpringBootTest @ActiveProfiles(';test';) @TestPropertySource(properties = [';ftp.enabled=true';]) @SpringBootTest(webEnvironment = RANDOM_PORT) @DirtiesContext class ImageGatewayApplicationTest {    @MockBean    private lateinit var authenticationService: AuthenticationService    @MockBean    private lateinit var panoramaService: PanoramaService    @MockBean    private lateinit var bmetryService: BmetryEventService    @Autowired    private lateinit var template: ProducerTemplate    @Autowired    private lateinit var restTemplate: TestRestTemplate    @EndpointInject(uri = ';mock:new-image';)    private lateinit var newImageMock: MockEndpoint    @Test    fun `upload with ftp`() {        val resource = ClassPathResource(TEST_PNG)        val tempFile = FileHelper.createTempFile(resource)        template.sendBodyAndHeader(TEST_FTP, tempFile, FILE_NAME, TEST_PNG) // <- template not initialised        // verify mock        verify<AuthenticationService>;(authenticationService).checkCredentials(TEST_USER, TEST_PW)        // clean up        tempFile.delete()    } </code> Here are the annotations as they were before the update. Nothing except the annotations changed (injection worked perfectly fine): <code>@RunWith(CamelSpringRunner::class) @ActiveProfiles(';test';) @TestPropertySource(properties = [';ftp.enabled=true';]) @SpringBootTest(webEnvironment = RANDOM_PORT) @DirtiesContext class ImageGatewayApplicationTest { } </code> The precise error I'm getting is this: <code>kotlin.UninitializedPropertyAccessException: lateinit property restTemplate has not been initialized </code> Note that it is not complaining about not finding beans or not being able to instantiate them or any of the stuff one might expect. It's as though the annotations are simply ignored. When I pause the code and look at the class, none of them are initialised. Nothing's being injected. I'm halfways certain that I'm missing some annotation, but I can't find it. I have tried adding @EnableAutoConfiguration, @ContextConfiguration and @UseAdviceWith (as that is in fact used in some tests), all with no result.

I wasn't even aware there's more of it, Intellij for some reason saw fit to hide it by default.

With the new Eclipse, I can also add maven repositories in the target platform file, so that is what I did.

All is well so far, I get all 20 or so plugins for the camel projects auto-generated. I add them in my manifest files, compile is working, everything is fine. Except when I try to start camel, I get a runtime exception saying <code>No language for 'simple' found</code>(something similar, I don't have the exact stackstrace now). The problem is this one:The <code>simple</code> language is in the core-languages module The <code>core-engine</code> module tries to load the <code>simple</code> language(from the <code>core-languages</code>) into the camel context <code>core-engine</code> and <code>core-languages</code> are 2 distinct plugins, thus the Equinox classloader will not allow <code>core-engine</code> to see any files in the META-INF folder inside the <code>core-languages</code> moduleI can only think of 2 possible solutions for this:Include Apache Camel as a jar dependency. The problem is I don't see any downloadable jar for the core Apache Camel in Maven. I will have to clone the repositories and build my own jar. Build a Maven project that takes all Camel core dependencies and outputs a single rcp plugin containing the dependencies. For this one I don't need to clone the Camel repositories, but I'm not 100% sure I can achieve this.For both approaches I think is quite cumbersome to add another Camel component afterwards, because it will probably involve modifying the custom project I created to include the new component(assuming <code>core-engine</code> needs to access it to load it into the context). Also I don't see how I can separate the Camel core from the optional components. Any ideas to make Camel work with Eclipse RCP?

I assume this issue and lack of Camel headers in <code>mockEndpoint</code>'s exchange may be related to separated <code>onException(Exception.class)</code> block in route definition and different context, but I'm not sure as I don't know Camel well enough. Is there any way to verify re-delivery attempts in such a simple test?

I can't seem to find a way to dynamically set the data source from the properties file. We already had a datasource bean that would connect to the correct database based on the environment, and so I tried referencing to that after annotating it with the <code>@QuartzDataSource</code> annotation. Ideally this would have been the cleanest solution. For example, <code>DataSourceConfig.java    @Bean(name=';myDataSource';)    @QuartzDataSource    @ConfigurationProperties(prefix=';org.quartz.mydatasource';)    @Autowired    public DataSource myDataSource(@Qualifier(';applicationProps';) BasePropReader applicationProperties) {        String connectionString = (String) applicationProperties.get(';spring.datasource.connection.url';);        return buildDataSource(applicationProperties, ';example-user';, ';example-pwd';, ';com.ibm.db2.jcc.DB2Driver';, connectionString);    }/////////////////////////quartz.propertiesorg.quartz.jobStore.useProperties = true org.quartz.jobStore.dataSource=myDataSource org.quartz.jobStore.tablePrefix = II_QRTZ_ </code> In our web applications we did something similar as the above, where in the quartz properties file we could refer to data sources that were already configured by environment by a JNDI url. For example: <code>org.quartz.jobStore.useProperties = true org.quartz.jobStore.dataSource=myDataSource org.quartz.jobStore.tablePrefix = II_QRTZ_org.quartz.dataSource.myDataSource.jndiURL=java:/MYDATASOURCE </code> We also tried setting the properties from <code>application.properties</code> but that didn't work - I suspect because we're using the Quartz component from Camel. I've tried reading up on reading environment variables from the properties file itself (via this thread), but all the variables I read end up as empty strings. Is this even possible via Apache Camel's Quartz? Ideally we would like to continue using Camel as it saves us a lot of refactoring.

However, when the route is deployed and given enough rights the endpoint creates a new queue on the address with the dots (<code>.</code>) escaped (i.e. <code>Consumer\\.dispatcher\\.VirtualTopic\\.ccncsi\\.fromEurope</code>) next to the existing one (i.e. <code>Consumer.dispatcher.VirtualTopic.ccncsi.fromEurope</code>) defined in <code>broker.xml</code>. I need to keep this consumer queue name because older clients connect through WebLogic and Openwire protocol using the VirtualTopic mapping.In that configuration I can observe that there is a consumer on the queue <code>Consumer\\.dispatcher\\.VirtualTopic.ccncsi\\.fromEurope</code> but I was expecting my endpoint to consume from the existing queue: <code>Consumer.dispatcher.VirtualTopic.ccncsi.fromEurope</code> I could not workout if the culprit was Camel or Artemis, but when <code>org.apache.activemq.artemis.core.protocol.core.ServerSessionPacketHandler#session.createSharedQueue(request.toQueueConfiguration());</code> is called, and the request (<code>org.apache.activemq.artemis.core.protocol.core.Packet</code>) is transformed in a <code>QueueConfiguration</code>, I can see that dots are already escaped. Is this normal behaviour? ",205    "Output": "This behavior is expected. The first thing to note here is that the name of the subscription queue (i.e. <code>Consumer\\.dispatcher\\.VirtualTopic\\.ccncsi\\.fromEurope</code> in this case) is an implementation detail under the broker's control. For unshared, durable subscriptions the broker will compose the subscription queue name with the client ID and the subscription name separated by a dot character (<code>.</code>). Since the dot character is a separator the broker escapes any existing dots in the client ID and subscription name. For shared durable subscriptions the client ID is left out and only the subscription name is used, but the broker still escapes the dots. That said, you can still get the behavior you want by using the fully qualified queue name in your Camel route, e.g.: <code>jms:queue:VirtualTopic.ccncsi.fromEurope::Consumer.dispatcher.VirtualTopic.ccncsi.fromEurope </code> I'm not super familiar with Camel so the extra colons in there (i.e. <code>::</code>) may need to be escaped, but hopefully you get the idea. Using the FQQN will allow you to create a consumer on the queue that will share the messages with the other Virtual Topic consumers in your environment.

In my humble opinion, I prefer generating a Karaf custom distribution that already contains all my bundles or features with all the dependencies. You can create your custom distribution to include your XML files or any extra configuration file. Finally, the end user takes your custom distribution, usually in the form of a zip file, and unzips it on the server to launch the application as a regular application or service. Apache Unomi works in this way: https://unomi.incubator.apache.org/. If you want to see an example of a custom distribution, take a look at these links: <code>https://github.com/apache/karaf/tree/main/examples/karaf-docker-example https://github.com/yupiik/esb </code> Another possible alternative is to have an instance of Karaf already configured on your server and deploy your application as a KAR file. The KAR files can include bundles and/or features and all the dependencies required. You can deploy the KAR file by moving it to the /deploy folder.

Essentially, the connection factory determines the approach; and the default connection factory will disconnect and reconnect regularly. For clarity, it is the Spring JMS code, not the connection factory, that is doing the disconnect and reconnect. In fact, it still does this even when using the solution outlined below. The caching connection factory vends a proxy to Spring JMS and keeps the connection open. Thanks to Doug Grove in the comments for pointing this out. To fix this, use a <code>SingleConnectionFactory</code> or its subclass, <code>CachingConnectionFactory</code> instead. Now, these can't accept user/password like the standard AMQ one can, and so you need to use a <code>UserCredentialsConnectionFactoryAdapter</code> to provide those. Simple, right? Here's some code: <code>ActiveMQComponent amqComponent = new ActiveMQComponent(); ActiveMQConnectionFactory cf = new ActiveMQConnectionFactory(); cf.setBrokerURL(';tcp://'; + amqServer + ';:'; + amqPort + '; jms.watchTopicAdvisories=false';);        UserCredentialsConnectionFactoryAdapter uca = new UserCredentialsConnectionFactoryAdapter(); uca.setUsername(amqUser); uca.setPassword(amqPassword); uca.setTargetConnectionFactory(cf);             CachingConnectionFactory ccf = new CachingConnectionFactory(uca); ccf.setClientId(amqClientID);             amqComponent.setConnectionFactory(ccf); amqComponent.setMaxConcurrentConsumers(1);             context.addComponent(';activemq';, amqComponent); </code> Note also, with this approach, you can only have one Camel Route using this Caching Connection Factory. If you try to add more than one, you'll get errors on the other routes. To fix this, you'll need to use a whole new Camel Context for each Route, and configure these connections factories on each.

I have tried searching online for information on how to set this option, but I haven't been able to find a solution,the results were either not relevant to camel based configuration or those were outdated.

Essentially, they key to using <code>AdviceWith</code> is to make sure that you are disabling the route builder: <code>@Override public boolean isUseAdviceWith() {    return true; }@Override public boolean isUseRouteBuilder() {    return false; } </code> According to dkulp's ';Apache Camel: Camel Test'; page, you need to disable the route builder in order to give Apache Camel time to apply the advised routes to the context: Method name: boolean isUseRouteBuilder() Description: If the route builders from returned from createRouteBuilder() or createRouteBuilders() should be added to the CamelContext used in the test should be started. If the CamelContext use in the test should be automatically started before test methods are invoked. Override when using advice with and return true.  This helps in knowing the adviceWith is to be used, and the CamelContext will not be started before the advice with takes place. This delay helps by ensuring the advice with has been property setup before the CamelContext is started. I haven't been able to run <code>./mvnw clean test</code> on the project with this, though, because I end up suffering from the same error. In order to be able to do that, I still need to put <code>@TestProfile(TestClassName.class)</code> in the test class's annotation: To force Quarkus JUnit Extension to restart the application (and thus also CamelContext) for a given test class, you need to assign a unique @io.quarkus.test.junit.TestProfile to that class. Check the Quarkus documentation for how you can do that. (Note that @io.quarkus.test.common.QuarkusTestResource has a similar effect.)

But I'm having an issue. For some wild reason, when some-entry-point sends the message to the file-upload endpoint, instead it ends up at the streaming-upload endpoint, where it will crash because it was expecting a file handle and got a byte array. I have done all I can with logging and breakpoints, and for all I can tell, this is indeed what happens. The message never arrives at file-upload, and it never arrives at do-the-other-thing, even though the conditions for that to happen are given. I've also verified that do-the-other-thing is the only route that forwards to streaming-upload. The only way I can explain the behaviour is that the message forwarded to file-upload ends up at the wrong endpoint. Can anybody tell me why? EDIT: Some new insights: The behaviour of messages being sent to the wrong queue is not consistent. In fact, it appears to be entirely random. I send a messages to any SEDA-queue endpoint, it's a cointoss which one will actually receive the message. Judging by the behaviour, I suspect that I'm completely misunderstanding hte underlying architecture here. It appears that there's only one SEDA-queue instance in my application, and the endpoints are both polling the same one. The first one to poll is the one that gets the message. That is not the behaviour I'd expect intuitively from something named ';endpoint';, but it would explain a lot. Any people here that actually know camel that can explain this to me? ",360    "Output": "It turns out that both those endpoints were backed by the same queue. My understanding of how camel works was woefully inadequate. When sending something to a SEDA-endpoint, it gets put on the designated queue, and SEDA endpoints will poll their queue at certain intervals. If two endpoints share the same queue, you have no control over which one will be first and receive the message. So if you want two different endpoints that are actually independent endpoints, you need to give them their own queue by making a bean for it and then injecting that into camel, like so: <code>@Configuration class QueueConfig(    @Value(';\\${capture.queueSize}';) private val queueSize: Int,    private val eventPublisher: ApplicationEventPublisher ) {    @Bean(';FirstBlockingQueue';)    fun createFirstQueue(): BlockingQueue<Exchange>; =        TODO(';instantiate queue here';)    @Bean(';SecondBlockingQueue';)    fun createSecondQueue(): BlockingQueue<Exchange>; =        TODO(';instantiate other queue here';)} </code> In the route builder: <code>from(';seda:first-enpoint?queue=#FirstBlockingQueue';)    // do thingsfrom(';seda:second-endpoint?queue=#SecondBlockingQueue';)    // do things </code> Now both endpoints are backed by their own queue, and will not steal each others messages.

Kafka Component path parameter For example, suppose you have the following topics:a/b/c0 a/b/c1 a/b/.. a/b/c40but you are interested in all topics except topic a/b/c40. One option is to use MQTT topic wildcards and drop the events from topic a/b/c40. However, the problem is that c40 takes up a lot of bandwidth (95+ %) and this extra load should be avoided. Another option is to create a consumer route for each topic and connect these routes to the same destination route. However, creating and managing 40 mqtt clients does not seem ideal to me or is the overhead negligible? A third option is to initialize the MQTT client with client.subscribe(topiclist) before starting the route and then pass the MqttClient via the advanced option 'client'. Paho Component client option But I am unsure when the client.connect(connectOptions) method should be executed. If this connect method is not executed before starting the route, I receive a 'client not connected' error. But when I execute it before starting the route, then it seemed that the route was no longer receiving all messages. Which option do you think is best? In the case of the 3rd option, when should the client.connect method be called? Before/After starting the route, in the route ... ? ",405    "Output": "In my case I went with the second option. It is unfortunate but yes the Paho MQTT client on Camel does not support multiple topics in the same route. I have had this exact issue few months back where I had data coming in over MQTT from multiple (10+) production lines and around 5-6 topics per line with decent sized messages (don't remember the exact size but around 2 - 3 KB per message). I created a configuration CSV and a small gawk script to generate the camel blueprint, this made the management of the routes very simple. I used one camel context per production line. This data was later processed in one destination topic. Performance was not an issue and the application was able to handle messages coming in every 10 - 15 ms. I usually keep two settings in mind when dealing with high frequency large payloads:set the maxInflight property to a high value like 500, 1000 depending on your needs. This ensures no messages are lost due to too many in flight messages. Use a lower qos, like 0 or 1. This ensures that the broker does not get backed up too much and its very rare that a message is lost/not delivered.Only draw back when having so many routes and contexts is that they take some time to start up, but that is not something you would have to do often so its acceptable.

The url looks like this: <code>http://baseOdataUrl/Customer('23 abc')/Orders</code> where <code>Customer</code> is a collection and <code>Orders</code> is a <code>NavigationProperty</code> with type <code>Collection(NAV.Orders)</code>. My camel route looks like this: <code>from(';timer:mytimer?period=1000';) .to(';olingo4://read/Customer('23 abc')/Orders?serviceUri=baseOdataUrl&;httpAsyncClientBuilder=#myHttpClientBuilder';); </code> which is failing with error: Illegal character in url which indicates, it's not being parsed properly at the position of the space.

So I just want to execute the working browser query from the beginning in camel and get the same correct results there. The httpClientBuilder is only being used for the NTLM authentication. I think, it's an easy query, which is running perfectly fine in browser, so there must be an issue with my syntax in camel.

First time this error happens to me ",435    "Output": "When you see the error <code>the trustAnchors parameter must be non-empty</code>, it usually means that the <code>KeyStore</code> could not be found. What's probably happening is that Camel is trying to look up your <code>KeyStore</code> file from the classpath. For this to work in native mode, the file needs to be added as a resource on the native image. You can do that with some configuration: <code>quarkus.native.resources.includes=*.jks </code> Here's the relevant section in the Camel Quarkus user guide: https://camel.apache.org/camel-quarkus/3.0.x/user-guide/native-mode.html#embedding-resource-in-native-executable Alternatively, if you want to read directly from the filesystem then you must prefix the resource string with the <code>file:</code> scheme.

It will look like below: <code>from(';jms:request.queue';)    .routeId(';my-route';)    .process(myProcessor)    .to(';jms:response.queue';).id(';response';)    .log(';work done';) </code> No need to say that the above example is heavily simplified. In reality it is relatively complex using some <code>filter</code> and <code>choice</code> constructs as well as two internal <code>direct</code> sub routes. The complexity makes you want to have unit tests in place to make sure the expected functionality is there. To avoid connecting to a JMS broker and have the test still verify the end to end flow the easiest way would be to mock the entry and the output endpoints using <code>AdviceWith</code> provided by Camel. Our environment configuration is driven from <code>yaml</code> files, and our unit tests looks like below: <code>@CamelSpringBootTest @ContextConfiguration(classes = {    CamelConfig.class,    JmsConfig.class    ...    // many other classes required to build the application context for this route }, // The initialiser below is needed to load yaml configuration  initializers = ConfigDataApplicationContextInitializer.class) @EnableConfigurationProperties(value = IbmMqConfig.class) @ActiveProfiles(';test';) @DirtiesContext(classMode = DirtiesContext.ClassMode.AFTER_EACH_TEST_METHOD) @UseAdviceWith class MyRouteTest {        @Autowired    private MyRouteBuilder myRouteBuilder;    @Autowired    private CamelContext camelContext;    @EndpointInject(uri=';mock:response-queue';)    private MockEndpoint mockResponseQueue;    @Produce(';direct:start';)    private ProducerTemplate producerTemplate;    @Test    void shouldWorkAsExpected() {        AdviceWith.adviceWith(';my-route';), camelContext,  new AdviceWithRouteBuilder(camelContext) {            @Override            public void configure() throws Exception {                replaceFromWith(';direct:start';);                weaveById(';response';).replace().to(mockReesponseQueue);            }        });        // The rest of the test goes here    }} </code> In other words what I done above was to follow the Apache Camel Spring testing documentation . The only difference I had was that rather than specifying the configuration via <code>@SpringBootTest</code> annotation I used <code>@ContextConfiguration</code> instead. This was because I wanted to to be able to load <code>yaml</code> config file. My problem is that when trying to run the test the camel context is not started and the route is not configured. It is only when explicitly calling <code>camelContext.start()</code> that the route is actually started. When using jUnit 4 and the old <code>RunWith</code> approach we never had to do this and everything worked perfectly. So my question is what I am doing wrong and how can I fix it?

Second created separate processor per each task(had to create long constructor to inject them all). Like: <code>from(';direct:someUrl';)  .process(myParseProcessor)  .process(myValidationProcessor)  .process(mySaveToDbProcessor)  .process(myPublishEventProcessor) </code> And in third one routes were calling each other(was super hard to see the full flow, because you had to jump across multiple classes).

Your first and second solution utilize a singleton pattern within Spring Boot while maintaining route visibility and transparency. Both is good and desirable. Thus, both ways are fine as far as I can tell. Whether you should use a service layer or Processor objects depends imho a bit on their respective purpose. Thus, if you can identify shared functionalities among different processing steps those steps could be organized in a service and called by whatever route needs them.

This causes a big problem with duplicates in our database. My understanding is the following:a file is put one the ftp server and is picked up by Camel a transaction is started the file is sent to the broker via JMS and is successful camel tries to ';rename'; the file to move it to the <code>completed</code> folder renaming fails and <code>GenericFileOperationFailedException</code> is thrown file is put back into the processing folder and reprocessed again from step 1.I created an integration test using the Spock Framework and MockFtpServer library. I have the following successful happy scenario: <code>def 'happy scenario'() {        given: 'one original file destination, one completed file destination'        fileSystem.add(new FileEntry(';/upload/mockFile.txt';, ';test';))        fileSystem.add(new FileEntry(';/upload/completed/mockFile.txt';, ';test';))        and: 'start the server'        ftpServer.start()        camelContext.start()        when: 'the file is actually sent to the ftp server'        remoteFile.storeFile(';src/test-integration/resources/files/mockFile.txt';, ';/upload/mockFile.txt';)        then: 'assert that it was'        // assert that the file is put on the ftp        ';test'; == remoteFile.readFile(';/upload/mockFile.txt';)        and: 'receive the file on the other end of the route'        def receivedMessage = jmsMessagingTemplate.receive(jmsDestinationQueue)        then: 'assert that that it is the correct file'        ';test'; == new String(receivedMessage.getPayload())    } </code> In the error scenario, I am stubbing the RENTO ftp command to throw GenericFileOperationFailedException <code>    def 'failed scenario - GenericFileOperationFailedException'() {        given: 'an original file location on the FTP'        fileSystem.add(new FileEntry(';/upload/mockFile.txt';, ';test';))        fileSystem.add(new FileEntry(';/upload/completed/mockFile.txt';))        and: 'a custom ERROR code for the RNTO command'        ftpServer.setCommandHandler(CommandNames.RNTO, new ExceptionCommandHandler())        and: 'start the server'        ftpServer.start()        camelContext.start()        when: 'the file is actually sent to the ftp server'        remoteFile.storeFile(';src/test-integration/resources/files/mockFile.txt';, ';/upload/mockFile.txt';)        then:'assert that it was'        ';test'; == remoteFile.readFile(';/upload/mockFile.txt';)        and: 'assert that message was received in the destination queue'        def receivedFromDestinationQueue = jmsMessagingTemplate.receive(jmsQueueName)        assertNotNull(receivedFromDestinationQueue.payload)        and: 'try to poll DLQ, original message should be sent there'        def dlq = StringUtils.substringAfterLast(errorUri, ';:';)        def receivedFromDLQ = jmsMessagingTemplate.receive(dlq)        assertNotNull(receivedFromDLQ)    } </code> This test fails: the message is never received from the DLQ where the message should have been sent because of the GenericFileOperationFailedException. I am polling both the destinationQueue, then the errorQueue because I noticed that the file WAS sent to the destination queue and processed. What I'm trying to achieve is to be certain that the file is only delivered once to the JMS broker, in all circumstances. If there are retries or errors anywhere in the process, the messages should be sent to the DLQ.

To get the original Exception you can use <code>template.send</code> and get the resulting exception from the resulting exchange through <code>.getException().getClass()</code>. <code>// Remove the onException blocks from route with this  // or getException() will return null Exchange result = template.send(';direct:example';, new DefaultExchange(context)); assertEquals(ExceptionB.class, result.getException().getClass());  </code> "616  },617  {618    "Instruction": "apache-camel",619    "Input": "I have a camel application running with Spring Boot.

In your example, <code>direct:products.create.validate.interceptor</code> and <code>direct:listAccountsPostHook</code> are both direct endpoints. In Apache Camel, direct endpoints are in-memory endpoints that allow you to send messages directly to another endpoint in the same JVM. The mapping between the endpoint and the method that consumes the messages is done by Camel's routing engine. More on Camel Direct endpoints you can read here. To understand how the messages are being consumed, you should look at the Camel routes that are defined in your project. In a Spring Boot project, you can define your Camel routes in a <code>RouteBuilder</code> class. This is where you would specify the mapping between the direct endpoint and the method that will consume the messages. For example, if you have a <code>RouteBuilder</code> class that looks like this: <code>public class MyRouteBuilder extends RouteBuilder {  @Override  public void configure() {    from(';direct:products.create.validate.interceptor';)      .to(';bean:myBean?method=executeCreate';);  } } </code> In this example, the direct endpoint <code>direct:products.create.validate.interceptor</code> is mapped to the <code>executeCreate</code> method in the <code>myBean</code> bean. The <code>?method=executeCreate</code> part of the to URI tells Camel to call the executeCreate method on the myBean bean when a message is received at the endpoint. So, in short, you should look for the Camel routes in your project that define the mapping between the endpoint and the method that consumes the messages.

For example, if file-watch-1 was added first, then the expression in file-watch-2 will evaluate to the value 3 instead of 1. I debugged my code and saw that camel uses an expressions cache which returns the upper value for the second route - but only for the expression used in the completionSize definition. Other expressions have the right value. I already took a look on the official documentation which isn't exactly stating that this is common behaviour for the way i specified the templateParameter.

To send a message to the Queue I use Postman and the Solace REST API. In order to differentiate the message type I add Content-Type to the header of the Http request in Postman. I used SDKPerf to check the message header consumed from solace and the message header is found under ';HTTP Content Type'; along with other headers. However, I can't seem to find a way to get this Content-Type from Camel Side. In the documentation it says <code>String header = exchange.getIn().getHeader(Exchange.CONTENT_TYPE, String.class); </code> However this always produces null. Any Ideas how to get the message properties in Camel? ",730    "Output": "EDIT: I think it's actually due to the fact that Camel is using QPid JMS, and there is no JMS API way of getting the Content Type, it's not in the spec.  Even though AMQP 1.0 does support <code>content-type</code> as a property.  But yeah, my suggestion of a custom property below is still probably the way I would go.https://camel.apache.org/components/3.20.x/amqp-component.html https://www.amqp.org/sites/amqp.org/files/amqp.pdf Edited for clarity &; corrections.  TL/DR: use a custom user property header. The SMF Content Type header in the original (REST) message is passed through to the consumed AMQP message as a property <code>content-type</code>, however the JMS API spec does not expose this; there is no way in standard JMS to retrieve this value.  It is, however, used by the broker to set the type of message (e.g. TextMessage).  Check ';Content-Type Mapping to Solace Message Types'; in the Solace docs. Using Solace's SDKPerf AMQP JMS edition to dump the received message to console (note this uses QPid libraries): <code>./sdkperf_jmsamqp.sh -cip=amqp://localhost:5672 -stl=a/b/c -md -qcurl http://localhost:9000/TOPIC/a/b/c -d 'hello' -H 'Content-Type: text'^^^^^^^^^^^^^^^^^^ Start Message ^^^^^^^^^^^^^^^^^^^^^^^^^^^ JMSDeliveryMode:                        PERSISTENT JMSDestination:                         a/b/c JMSExpiration:                          0 JMSPriority:                            4 JMSTimestamp:                           0 JMSRedelivered:                         false JMSCorrelationID:                       null JMSMessageID:                           null JMSReplyTo:                             null JMSType:                                null JMSProperties:                          {JMSXDeliveryCount:1;} Object Type:                            TextMessage Text:                                   len=5  hello </code> The header does not get mapped through, but does get used to set the message type.  If I remove that HTTP header, the received AMQP message is binary.  But since other types of Content-Types also map to TextMessages (e.g. <code>application/json</code>, <code>application/xml</code>, etc.), the fact you're receiving a TextMessage is not enough to infer exactly what Content-Type you published your REST message with. For completeness, I used WireShark with an AMQP decoder, and you can see the header present on the received AMQP message: <code>Frame 3: 218 bytes on wire (1744 bits), 218 bytes captured (1744 bits) on interface \\Device PF_Loopback, id 0 Null/Loopback Internet Protocol Version 4, Src: 127.0.0.1, Dst: 127.0.0.1 Transmission Control Protocol, Src Port: 5672, Dst Port: 60662, Seq: 2, Ack: 1, Len: 174 Advanced Message Queueing Protocol    Length: 174    Doff: 2    Type: AMQP (0)    Channel: 2    Performative: transfer (20)    Arguments (5)    Message-Header        Durable: True    Message-Annotations (map of 1 element)        x-opt-jms-dest (byte): 1    Message-Properties        To: a/b/c        Content-Type: text                       <----------    Application-Properties (map of 1 element)        AaronEncoding (str8-utf8): CustomText    AMQP-Value (str32-utf8): hello </code> So my suggestion is this: Set an additional custom header, a User Property, which will get passed through to the AMQP message: <code>curl http://localhost:9000/TOPIC/a/b/c -d 'hello' -H 'Solace-User-Property-AaronEncoding: CustomText' -H 'Content-Type: text'JMSDestination:                         a/b/c JMSProperties:                          {AaronEncoding:CustomText;JMSXDeliveryCount:1;} Object Type:                            TextMessage Text:                                   len=5  hello </code> My always-goto guide for Solace REST interactions: https://docs.solace.com/API/RESTMessagingPrtl/Solace-REST-Message-Encoding.htm Hope that helps!

If incoming message already has JMSCorrelationID, Camel will not change it, and will copy that value to the reply.(I guess that if you manually set JMSCorrelationID in client side, Camel will stop setting it for you). So basically, message without JMSCorrelationID means it's new message which hasn't passed through my client application. I think only client side should set it, especially in my case where original message and replies are put into the same queue, where client needs a mean to filter out replies. Also, to stop Camel from ';capturing';, you need to make sure other two things:no concurrent consuming is happening the queue is empty before your test(no leftover from previous test), as all my tests are running in sequential order with <code>@Order</code>.For 1, set <code>replyTo(Max)ConcurrentConsumer</code> both to <code>1</code>, so that no concurrent consuming is happening; only one thread process this message. <code>ActiveMQComponent component = ActiveMQComponent.activeMQComponent(url); // we use request-reply mode so (max)ConcurrentConsumers are not taken into account; must set ';replyTo(Max)ConcurrentUsers';. // see https://camel.apache.org/components/3.20.x/activemq-component.html component.setReplyToConcurrentConsumers(1); component.setReplyToMaxConcurrentConsumers(1); // seems every pod will have max consumers </code> For 2, if last test rollbacked one message and put it back to the queue, I need to consume it before running the next test.At the very last, we separate the queues so even capturing is happening, it does not matter any more.

Why? I see this part in <code>SimpleMainShutdownStrategy</code> class: <code>    @Override    public boolean isRunAllowed() {        return !completed.get();    }    @Override    public void addShutdownListener(ShutdownEventListener listener) {        listeners.add(listener);    }    @Override    public boolean shutdown() {        if (completed.compareAndSet(false, true)) {            LOG.debug(';Shutdown called';);            latch.countDown();            for (ShutdownEventListener l : listeners) {                try {                    LOG.trace(';ShutdownEventListener: {}';, l);                    l.onShutdown();                } catch (Throwable e) {                    // ignore as we must continue                    LOG.debug(';Error during ShutdownEventListener: {}. This exception is ignored.';, l, e);                }            }            return true;        }        return false;    }    @Override    public void await() throws InterruptedException {        LOG.debug(';Await shutdown to complete';);        latch.await();    } </code> So maybe it is because in the 1st case, <code>ShutdownController</code> has no instance so the constructor is called, and wait for 10s; but in the 2nd test, the instance is created so it does not call constructor. But why shutdown is called before the integration test runs? In both cases, Quarkus app starts before Camel. Both tests have similar structure: <code>@QuarkusIntegrationTest @QuarkusTestResource(value = WiremockResource.class, restrictToAnnotatedClass = true) @QuarkusTestResource(value = InMemoryAMQResource.class, restrictToAnnotatedClass = true) @TestProfile(MyIntegrationTestProfile.class) class MyOutboundMessageFormatIT extends MyIntegrationTestSupport { // the base class have a lot of fields like connetion, session, etc., which are used in @BeforeAll and @BeforeEach, etc.     private static final Logger LOG = Logger.getLogger(MyOutboundMessageFormatIT.class);    @InjectInMemoryAMQ    protected BrokerService brokerService;    @InjectWiremock    protected WireMockServer wireMockServer;    @Override    WireMockServer getWiremock() {        return wireMockServer;    }    @Override    BrokerService getBroker() {        return brokerService;    }    @BeforeAll    protected static void start() throws Exception {        LOG.debug(';Connecting to AMQ';);        connectToAMQ();    }    @AfterAll    protected static void stop() throws Exception {        LOG.debug(';Stopping AMQ';);        session.close();        connection.stop();        connection.close();    }    @BeforeEach    protected void stub() {        // global stubs        stubAllFieldsOK();        stubOauthOK();    }    @AfterEach    protected void clearWiremockRequestsJournal() throws JMSException {        // clear reply queue for next test        consumeOnlineReply();        assertEmptyNonOnlineReply();        waitTillTokenExpires();        wireMockServer.resetRequests();    }    ... </code> ",760    "Output": "At last, at the end of the log I see the cause: <code>2023-01-05 14:13:52,530 INFO  [org.apa.cam.imp.eng.AbstractCamelContext] (main) Apache Camel 3.14.1 (camel-1) shutdown in 942ms (uptime:1s341ms) 2023-01-05 14:13:52,549 ERROR [io.qua.run.Application] (main) Port 8081 seems to be in use by another process.

The original issue is that I was reusing the JSON message body between tests, and somehow ActiveMQ is ignoring the message, so no message entered the queue, so 2nd test was not running; also, changing stubbing out of Wiremock resource class seems impossible(at first I let Wiremock return 200, but in the last test I want to simulate 404 case), that's why I wanted to separate the tests. Now, I use an id to mark the stub I want to change, and in test I call <code>wiremockServer.editStub()</code> to change the stub, also I stop tests from running in parallel with <code>@TestMethodOrder(value = MethodOrderer.MethodName.class)</code>, then things start to work.

So I want to try set no destination; however, seems that Camel expects the body to be the incoming message POJO. How can I send the modified body? https://camel.apache.org/components/3.19.x/eips/requestReply-eip.html has an illustration, where the request and reply have different color. I suppose they are different message, which makes sense; who wants the original message?In the last step of my route I did: <code>exchange.getIn().setBody(myString);</code>; also tried <code>exchange.getMessage().setBody(myString);</code> but I got error:Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: java.lang.String to the required type: com.example.IncomingMessage with value {';failedEndpointsAndCauses';:{},';message';:';Message does not contain some ID field';,';status';:';ERROR';}which is exactly what I want to put into the response. <code>IncomingMessage</code> is the POJO coming in in the first place from ActiveMQ. Seems that Camel expects my outgoing response POJO to be the same type as incoming message. I cannot <code>getOut().setBody()</code>, as this is deprecated. I don't know why(maybe I know, that it's better just to <code>getIn()</code> and <code>setBody()</code>, because we need to copy everything from IN to OUT; but in the annotation of <code>@Deprecated</code> there are no explanations. ) Similar question: How exactly is JMSReplyTo handled by Apache Camel? When does camel implicitly utilises the destination? which suggests set <code>disableReplyTo</code>. But why Camel is not following the EIP of Request and Reply? I want a different body as response.

I also have to <code>.marshal().json(JsonLibrary.Jsonb, OutboundMessage.class)</code> before sending the reply to make sure the message body is a valid string message.But then, a similar error happens where it is like <code>Caused by: org.apache.camel.NoTypeConversionAvailableException: No type converter available to convert from type: byte[] to the required type: com.example.IncomingMessage with value [Bxxxxxxx</code>. I notice that it is now a byte array, meaning that it is already marshalled correctly, but Camel continues to try to process it even after sending. So, after trying all possible, I add <code>.stop()</code> after sending, and this error is gone. Notice that <code>.stop()</code> also ensures the callback(sending reply to reply queue in <code>JMSReplyTo</code> header) is executed, so you will always want to call <code>stop()</code> in request/reply mode. So, make sure you:return the same POJO at the end of each logic path/branch, especially after a short circuit/premature return one stop the route at the end, to stop Camel to do further conversion.

We have config in a Map, organized by ';agentId'; as key, and list of ';customerConfigs'; as value.By one field in the message, we decide which agent this message should send toAnd then, we iterate all customers under that agent, checking what fields each one need, and remap message accordinglyWe also filter by checking if the message content meets customer's criteria. If yes, we do OAuth against the OAuth url of that customer, and send message to them. If not, skip. We are doing it with Camel, and by now, all steps from receiving to mapping and retrieving configs and so on, is defined in a bean.(<code>.bean(GeneralBean.class)</code>). It works. But now, we want to retry against customer endpoints, and I decide to separate steps into several Camel steps, because I don't want to retry the whole receiving/remapping/retrieving configs like now. I just want to retry last step, which is sending. Now comes the question: which Camel component should I use?I think recipient list is good, but not sure how. Maybe ';Dynamic router'; is better?When defining steps, when I am retrieving the config of each customer, one object in the exchange body(let's call it <code>RemappedMessage</code>) becomes two (<code>RemappedMessage</code> and a list of <code>CustomerConfig</code>). They have one to many relationship. How do I pass down these two objects to next bean? Or should I process them together in one bean? In the <code>Exchange</code>? In <code>@ExchangeProperties Map<String, Object>; properties</code>? The latter works, but IMO is not very Camel. Or define a tuple class to combine them? I use it a lot but think it's ugly.I don't think there is some syntax in Camel to get some properties of object in the Exchange and put it into the <code>to()</code> as url and as basic credentials username and password? In general, I want to divide the process into several steps in a Camel pipeline, but not sure how to deal with ';one object split into more objects and they need to go hand in hand to downstream'; problem.

But obviously I cannot return 2 objects together. ",820    "Output": "Recipient List is ideal when you want to send the same message to multiple endpoints and you know what those endpoints are before entering the Recipient List. The Dynamic Router can route messages to a number of endpoints, the list and order of which not necessarily known at the time the router is entered. Since you have a one-to-many situation, Dynamic Router may be a better fit. A simpler approach that might work is to prepare a List of tuples. Each tuple would contain a <code>CustomerConfig</code> and a <code>RemappedMessage</code>. You would then split the list and in the splitter send the message to the agent. For the tuple you could use something like ImmutablePair, a <code>Map</code>, or just a two-element <code>List</code>. As for setting a url and username/password, I'll assume you're using Camel's HTTP component. It's probably best to provide these values as headers since the http component allows this. The URL can be set with the CamelHttpUri header. And the HTTP component will generally pass message headers as HTTP headers, so you can set things like the <code>Authorization</code> header just by setting a message header with the same name. And there's definitely support for setting headers from values in the exchange and message. E.g. <code>// assumes the body is a List in which the first element is a CustomerConfig .setHeader(';Authorization';, simple(';${body[0].authValue}';)) </code> In reality, you'll probably have to do a little bit more work for authorization. E.g, if it's basic auth, you'll have to compute the value you want to use. I'd set that in a header or property and then refer to it like: <code>.setHeader(';Authorization';, simple(';${header.basicAuthValue}';)) // or .setHeader(';Authorization';, simple(';${exchangeProperty.basicAuthValue}';)) </code> "821  },822  {823    "Instruction": "apache-camel",824    "Input": "I am trying to call an external API with an access token parameter in query, by taking it from header, however for some reason it doesn't work, API returns error <code>Access token not configured</code>.

I've read on top of that, that we should a connection pool but I have only seen an example of this in the first approach (1st code sample). I guess it does the same when done with the DataSource as a service since I can call it from multiple bundles. Thanks for regarding, best regards ",850    "Output": "In Apache Karaf versions 4.2.x - 4.4.x it's generally a good practice to use OSGi Services to share DataSource type objects. This makes your bundles more loosely coupled and when making changes to connection parameters you'll only need to change them for the service instead of having to reconfigure every bundle that uses the said DataSource. You can also create your own shared resources and expose them as services using blueprints, declarative service annotations or the ';hard way'; using activator and bundle context. I also recommend to checkout features pax-jdbc-config and pax-jms-config features as they allow you to create DataSource and ConnectionFactory type services from config files. These look for config files using <code>org.ops4j.datasource</code> <code>org.ops4j.datasource</code> prefixes in their name e.g <code>org.ops4j.datasource-Example.cfg</code> Only downside for using services is that they're specific to Karaf and OSGi so if you ever need to move your integrations to non-osgi environment you'll have to figure out another way to inject data sources to your integrations. [edit] With shared resources I mean resources you might want to access from multiple bundles. These can be anything from objects that contain shared data, connection objects for cloud blob storages, data access objects, slack or discord bots, services for sending mails etc. You can publish new services using blueprints from beans using service tag. Below is example from OSGi R7 Specification <code><blueprint>;   <service id=';echoService';             interface=';com.acme.Echo'; ref=';echo';/>;   <bean id=';echo'; class=';com.acme.EchoImpl';>;     <property name=';message'; value=';Echo: ';/>;   </bean>; </blueprint>;  </code> <code>public interface Echo {  public String echo(String m); } public class EchoImpl implements Echo {  String message;  public void setMessage(String m) {    this.message= m;  }  public void echo(String s) { return message + s; } }  </code> With OSGi Declarative services (DS) / Service Component Runtime (SCR) annotations you can publish new services with java. <code>@Component public class EchoImpl implements Echo {  String message;  public void setMessage(String m) {    this.message= m;  }  public void echo(String s) { return message + s; } }  </code> Another example can be found from Official Karaf examples in github.

The problem starts when I try to deploy this project on Karaf. mvn:install generates the required jar with blueprint files and manifest file correctly formed. I copy this over to the deploy folder in Karaf. The bundle installation is successful. But it does not start. I get an exception saying that the bundle was not able to detect the MariaDB java client. This does not make sense to me because I have it installed (using bundle:install -s mvn:...) on Karaf. I did this for all other dependencies like fasterxml, dbcp2 etc. My requirement is strict: I need to be able to define the data source in my blueprint file.

Indeed, in the case of a bean, you could only specify the method to invoke, Camel is able to inject the body as a parameter of your method and automatically converts it into the expected type which is <code>String</code> in your case. Refers to https://camel.apache.org/manual/bean-binding.html#_parameter_binding for more details. Regarding the SQL producer, assuming that you did not change the default configuration, the proper way is to rather use the placeholder that is <code>#</code> by default, Camel will automatically use the content of the body as parameters of the underlying <code>PreparedStatement</code>. So you should retry with: <code><to uri=';sql:insert into dbo.table_example (OT) VALUES (#)';/>; </code> If you really want to explicitly refer to the body in your query, you can rather use <code>:#${body}</code> as next: <code><to uri=';sql:insert into dbo.table_example (OT) VALUES (:#${body})';/>; </code> Misuse of named parameter If you only use <code>#body</code> as you did, Camel interprets it as a named parameter so it will try to get the value from the body if it is a map by getting the value of the key <code>body</code> otherwise it will try to get the value of the header <code>body</code> but in your case, there are no such values, therefore, you end up with an error of type <code>Cannot find key [body] in message body or headers to use when setting named parameter in query [insert into developers (name) values :?body;] on the exchange </code> "891  },892  {893    "Instruction": "apache-camel",894    "Input": "I tried unit testing Apache Camel and I started out with a real basic case where my route looks like that: <code>public class TestRoute extends RouteBuilder {    @Override    public void configure() throws Exception {        from(';jpa:Data';).to(';jpa:Data';).id(';testId';);    } } </code> Now the following approach didn't work.

Use a more specific pattern that matches only with your to endpoint like <code>jpa:Data</code>.

I have a requirement to implement an FTP/FTPS/SFTP client, which would be used to fetch the files from the respective servers. I was looking into the possibility of using Apache Camel to do this but I am still confused after going through the examples and the tutorials. The requirement is to fetch the files from the FTP/SFTP servers when the request is received from the scheduler. Following is the route created using EndPoint-DSL <code>@Component public class FtpReceiveRoute extends EndpointRouteBuilder {@Override public void configure() throws Exception {    from(            ftp(';localhost:2001/home/admin';)            .account(';admin';)            .password(';admin12345';)            .recursive(true)        )    .routeId(';ftpReceive';)    .log(';From done!';)    .to(';log:ftp-log';)    .log(';To done!!';); } </code> } I am trying to use the above route by invoking it when the request is made to fetch the file like below. <code>@Override protected FtpResponse doMessage(String param, FtpRequest req) {    FtpResponse response = new FtpResponse ();    CamelContext ctx = new DefaultCamelContext();        ctx.addRoutes(##route); //FtpReceiveRoute, add the Routebuilder instance as EndpointRouteBuilder is acceptable.    ctx.start();    //Might need to induce sleep so that all the files are downloaded    ctx.stop();    return response; } </code> The confusion is around how to invoke the Camel process with the route. I have used EndpointRouteBuilder to create the route because of the type-safe creation of the endpoint URI. I am not getting an option to add this route to the CamelContext as it expects the RouteBuilder instance which is not type-safe. Further, the CamelContext is the engine and to invoke the route I would need to start and stop this engine. This I am not able to digest if I need to start and stop the engine to execute a route then I would need to induce some sleep in between so that all files are downloaded. Just to add there are more routes that I need to add with the implementation. Once the engine is started it would load and execute all the added routes which is not the requirement. Maybe I am not getting how to use this properly. Any resources aiding my situation are welcome. Thanks. ",900    "Output": "You should not create and start new camel context every time you want to fetch file from server. What you should do instead is start one when your application starts and use that for all your exchanges. You can use Spring-boot to initialize CamelContext and add annotated RouteBuilders to it automatically. Check the maven archetype camel-archetype-spring-boot for example. If you want to call camel routes from Java you can Inject CamelContext to your bean and use it to create ProducerTemplate. This can be used to invoke Routes defined in the RouteBuilder.

The type of message body is of type java.lang.Object so in order to access <code>getName</code> method of your <code>MyClass</code> you need to cast the body to MyClass. You don't really need extra variable for this but it's often cleaner to store the result of cast to a separate variable and do whatever with the variable after. Otherwise you'd have to do something like this every time you want access public methods and variables of the object: <code>// Using getBody(Class) (exchange.getMessage().getBody(MyClass.class)).getName();// Using basic Java syntax for casting ((MyClass)exchange.getMessage().getBody()).getName(); </code>to access the value present in MyClass.name, we have to do myClass.getName() inside ProcessorClass. Is this the only way to access model class data after unmarshalling ?No, you could also use bean with method with MyClass as parameter and camel will do the casting automatically when the method gets called. <code> from(';timer:timerName?period=3000';)    .setBody(constant(new MyClass(';Bob';)))    .bean(new MyBean());class MyBean {    public void someMethod(MyClass myClass) {        if(myClass != null) {            System.out.println(myClass.getName());        } else {            System.out.println(';Given MyClass instance was null..';);        }    } }class MyClass {    private String name;    public MyClass(String name) {        this.name = name;    }    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    } } </code> You could also access it using simple-language. Alternatively you could also access it with lamda + casting <code>.setHeader(';name';).exchange(ex ->; {    return ex.getMessage().getBody(MyClass.class).getName(); }) </code> Casting is pretty basic stuff when it comes to Object oriented programming so you might want to do a refresher on that before continuing with Apache Camel. Since message body of an exchange can hold pretty much anything you'll always need to cast it to actually use it. Either you do it in processor or camel does it automatically in background as with many of the examples above. Same goes for headers and exchange properties.

Aggregation Strategy is used to configure how you want camel to combine one or more exchanges. This means it can be used to combine current exchange to a incoming exchange with enrich or to group multiple exchanges in to one when when using split or aggregate.How can i know which one to use?They're completely different patterns, one is for enriching exchanges with new data and one grouping exchanges together. In terms of defining routes with Camel Java-DSL use of <code>.enrich()</code> is pretty uncommon as generally it's enough to call the endpoint directly with <code>to(';uri';)</code>. More common is <code>.pollEnrich(';uri';)</code> as with it one can use consumer endpoints like file, ftp or jms to enrich the exchange. Meaning if you need data from two or more files on a route you can use it to do so. When it comes to <code>.aggregate()</code> it's mainly used to group exchanges together and handle them as a group after some pre-determined condition has been met like for example every 100 exchanges or after 10 seconds of no new exchanges.

Why?The method above uses Camel Rest-DSL which allows you to define rest endpoints using java instead of fiddling URI Strings. The method below uses camel-rest component which works almost identically except for the fact that you use URI strings to configure it. It's possible that Rest-DSL uses this under the hood. The example you're referring to used camel version 3.14.0 but it seems both <code>.route()</code> and <code>endRest()</code> methods have been quietly removed from RestDefitinion which causes the exception <code>Cannot resolve method 'route' in 'RestDefinition</code>. Instead of <code>route()</code> you should use <code>to(';direct:endpointName';)</code> instead. My guess is that developers wanted to move most of the routing logic away from the RestDSL to keep it clean. Here's example for Camel 3.18.1 <code> // What I used to test this restConfiguration()    .component(';undertow';)    .host(';localhost';)    .port(8091);// http://localhost:8091/api/hello rest(';/api';)    .description(';Some description';)    .post(';/hello';)        .consumes(';text/plain';)        .produces(';text/plain';)        .to(';direct:someRoutePost';)    .get(';/hello';)        .produces(';text/plain';)        .to(';direct:someRouteGet';);from(';direct:someRouteGet';)    .routeId(';someRouteGet';)    .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(200))    .setBody(constant(';Hello world';));from(';direct:someRoutePost';)    .routeId(';someRoutePost';)    .setHeader(Exchange.HTTP_RESPONSE_CODE, constant(405))    .setBody(constant(';POST not allowed on this route';)); </code> Tested by generating project using maven <code>camel-archetype-spring-boot</code> archetype version <code>3.18.1</code>, added in following dependency. <code><dependency>;    <groupId>;org.apache.camel.springboot</groupId>;    <artifactId>;camel-undertow-starter</artifactId>; </dependency>; </code> "1011  },1012  {1013    "Instruction": "apache-camel",1014    "Input": "I'm trying to use the camel-bean-validator dependency in my project but I have a problem with group validation.

    long numberOfLines = 0;     if(oldExchange != null) {        sum = (Long) oldExchange.getProperty(';sum';);        numberOfLines = oldExchange.getProperty(';numberOfLines ';);     }       sum = sum + ((Line)newExchange.getIn().getBody()).getColumnValue();       numberOfLines ++;       newExchange.setProperty(';sum';, sum);       newExchange.setProperty(';numberOfLines';,numberOfLines);       oldExchange.setProperty(';CamelSplitComplete';, newExchange.getProperty(';CamelSplitComplete';)); //This is for the completion predicate       return newExchange;  } } </code> Route: <code> .split(body().tokenize(';\\r | ';),sumAggregationStrategy)   .completionPredicate(simple(';${exchangeProperty.CamelSplitComplete} == true';))   .process(';fileProcessor';).to(';file:your_file_name?fileExist=Append';);

By default, when an Exchange created using the File component's input completes its Route the file is moved to <code>$inputLocation/.camel/</code>. However, when using an Aggregator, after the Exchange goes through the aggregation step it goes on to complete the remainder of the Route outside of the Aggregation step (which there may or may not be).  This means that the Exchange finishes the Route and if a File Consumer was used it causes the file to be moved to  <code>$inputLocation/.camel/</code>. At some later time the Aggregator will complete and when it does so the aggregated File references will be invalid, because the file was moved on disk when the regular Exchange completed the Route. The following depicts a simple Route that shows the issue.  The referenced Processor <code>doSomethingWithTheAggregatedFiles</code> will find that the files in question do not exist at their stated location (as they have already been moved (to <code>workdirs/in/.camel/</code>): <code>  @Override  public void configure() throws Exception {    from(';file:workdirs/in/';)      .aggregate(constant(true), AggregationStrategies.groupedExchange())        .completionTimeout(10*1000) // 10 seconds        .process(';doSomethingWithTheAggregatedFiles';)        .end()    .log(';file completed route: $simple{header[CamelFileName]}';)    .end();  } </code> Is there something missing here?  Is there no way to get it to ';wait'; until the aggregated exchange completes? Looking at the <code>ZipAggregationStrategy</code> I see that it doesn't suffer this issue because it reads the content of the files during the aggregation step and adds it into the ZIP file - essentially taking a copy of the data as the aggregation step occurs.  Preferably I do not want to take a copy, as my input may be large. ",1085    "Output": "You could set the file consumer's noop to <code>true</code> and implement a simple processor to move the files after your aggregation is complete. <code>.process(e ->; {    String name = e.getIn().getHeader(';CamelFileNameConsumed';, String.class);    Files.move(        Path.of(name),        Path.of(';.camel';).resolve(';name';)); }) </code> Another solution that might work for you is to force the Aggregator to run in the same thread as its caller: <code>.aggregate(constant(true), AggregationStrategies.groupedExchange())    .executorService(new SynchronousExecutorService())    ... </code> This results in all aggregations completing prior to the File component being notified that the route is complete.

The Camel setup has property count which I set to <code>10</code>, and expect to get <code>10</code> new tweets in one poll, but the problem is that template offers only one tweet per Camel request: <code>for (int i = 0; i < 15; i++) {    // I would expect here List or stream, but I can get only single `Status`    final Status tweets = consumerTemplate.receiveBodyNoWait(String.format(';twitter-timeline://home?sinceId=%s&;count=10';, sinceId), Status.class);    // just to show that I change that property    if (nonNull(tweets)) {         sinceId = tweets.getId();    }} </code> So my question is why I get only one tweet per poll even if count is set (a value more than <code>1</code>). Is there any better way or running that template, or something I can use instead while respecting downstream Twitter rate limits? ",1190    "Output": "The <code>ConsumerTemplate</code> is based on a <code>PollingConsumer</code> under the hood, which as the name implies, pulls <code>Exchage</code>s one at a time hence why you are receiving only 1 <code>Status</code> (== 1 <code>Exchange</code>) even while setting a <code>count</code> endpoint option. It is almost hard (and error-prone) to implement tweets (or other <code>Exchange</code>s) consumption the right way. Indeed this is already offered out-of-the-box with the Apache Camel Twitter Component consumer. Here down a sample of a route to consume user public activity (timeline) using the twitter-timeline component: <code><routes xmlns:xsi=';http://www.w3.org/2001/XMLSchema-instance';        xmlns=';http://camel.apache.org/schema/spring';        xsi:schemaLocation=';            http://camel.apache.org/schema/spring            https://camel.apache.org/schema/spring/camel-spring.xsd';>;    <route id=';twitter-timeline'; autoStartup=';true';>;        <from uri=';twitter-timeline:USER?user=some-user&;amp;consumerKey=your-app-key&;amp;consumerSecret=your-app-key-secret&;amp;accessToken=your-app-access-token&;amp;accessTokenSecret=your-app-access-token-secret';/>;        <log message=';${body}';/>;    </route>;</routes>; </code> This will leverage the default polling configured delays which you can tweak based on your preferences to address any rate-limits. In your case for example, to respect 15 requests per 5 mins, you can set the consumer to poll each 20 seconds for one page: <code><from uri=';twitter-timeline:USER?user=some-user&;amp;count=100&;amp;numberOfPage=1&;amp;delay=20000';/>; </code> "1191  },1192  {1193    "Instruction": "apache-camel",1194    "Input": "I am using the camel-jaxb component to unmarshall xml zipped in the Artemis queue, but jaxb in my local is not able to find the <code>jaxb.index</code> file.
