Resolution: Not A Problem
> 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:
> {code:title=ExampleCXF.java|borderStyle=solid}
> public class ExampleCXF extends RouteBuilderComponent {
> private static final String CXF_RS_ENDPOINT_URI =
>
> "cxfrs://http://localhost:9000/customerservice?resourceClasses=org.ow2.jonas.sample.jaxrs.api.ICustomerService";;

> private Log logger = LogFactory.getLog(this.getClass());
> private ICamelService camelService;
> /**

> /**
> * Name of files exchanged in CXF. Used by the second route.
> */
> private Map<String, String> filenames = new HashMap<String, String> ();
> /**
> * Constructor: saves the BundleContext.
> */
> public ExampleCXF(final BundleContext bundleContext) {
> super(bundleContext);
> }
> /**
> * Adds the OSGi HTTP service port and the
> * <code>target/fileToHelloService</code> directory into
> * {@link RouteBuilderComponent#registryReplacements}, calls
> * {@link RouteBuilderComponent#start()} and launches a self-test.
