org.apache.camel.NoSuchEndpointException

[larsroediger]

I've tried to set up a Camel-Route in the following way:

extract from class com.larsroediger.activemqtest.RouteToQueueA

public void configure() throws Exception {  

  from(file:/in/)

    .convertBodyTo(String.class)

      .to("activemq:queue:QueueA");

}

and the corresponding XML under META-INF/spring is:

When I deploy the Bundle in Fuse ESB then I get the following Error:

org.apache.camel.NoSuchEndpointException: No endpoint could be found for: activemq:queue:QueueA, please check your classpath contains the needed camel component jar.

        at org.apache.camel.util.CamelContextHelper.getMandatoryEndpoint(CamelContextHelper.java:55)

        at org.apache.camel.model.RouteType.resolveEndpoint(RouteType.java:99)

...

The camel component is supposed to be on the classpath, the corresponding Bundles (camel-jms, camel-spring, camel-osgi, camel-core) are active. Camel's Java DSL automatically creates Destinations (Queues and Topics), when I use the from method, does it?

Any suggestions, what might be the problem here?

Hi

In your route you have activemq defined here:

.to("activemq:queue:QueueA");

it is the scheme of the URI (the text before the first colon).

So Camel expects to find a component with this name. As the name suggests its a AMQ broker, you need to define it as well.

In your configuration below, you have define a generic JMS component. What you can do is either:

1) change this generic from jms to activemq

2) or change the activemq in your route to jms

3) Or use ActiveMQ directly

If you want to use AMQ broker then there is a better component provided in the

activemq-camel.jar that is optimized for AMQ-Camel.

You can find this jar in the FUSE maven repo

For instance the latest release is here:

http://repo.fusesource.com/maven2/org/apache/activemq/activemq-camel/5.3.0.0-fuse/

And then you need to define a spring bean with the name activemq

And there is a bigger tutorial on Camel in FUSE ESB 4.x (OSGi) here:

The author is currently in the writing of a 2nd part with more to come.

Thanks a lot, the first hint worked out. Didn't try the other ones.
