Claus Ibsen commented on CAMEL-4185:
------------------------------------
Please use the mailing list first to get help with using Apache Camel as we
encourage people to do
http://camel.apache.org/support
Then after a bit of mails and suggestions on the mailing list, and if indeed
there is an issue in Camel, then at that time, a JIRA can be created.
> CXFRS can't find my JAX-RS resource classes
> -------------------------------------------
>
> Key: CAMEL-4185
> URL: https://issues.apache.org/jira/browse/CAMEL-4185
> Project: Camel
> Issue Type: Bug
> Components: camel-cxf
> Affects Versions: 2.7.2
> Environment: Ubuntu 10.10 | Server Camel-JOnAS 1.7.0
> Reporter: Miguel González
>
> I'm trying doing some testing to expose an OSGi/iPOJO component with a REST
> interface too. When I install the bundle on Camel-JOnAS, CXFRS can't build
> the route because it can't find any resource classes, even if I indicated it
> properly in the URI. To test, I'm using the classes found in
> https://svn.apache.org/repos/asf/camel/tags/camel-2.2.0/components/camel-cxf/src/test/java/org/apache/camel/component/cxf/jaxrs/testbean/
> and launching with the following one:
