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:
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";;
/**
* The logger.
*/
private Log logger = LogFactory.getLog(this.getClass());
private ICamelService camelService;
/**
* HTTP port number.
*/
private String httpPort = "9000";
/**
* 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.
*/
@Override
public void start() throws Throwable {
ClassLoader cl = Thread.currentThread().getContextClassLoader();
System.out.println("Current thread class loader = " + cl);
try{
Thread.currentThread().setContextClassLoader(ExampleCXF.class.getClassLoader());
System.out.println("Bundle class loader = " +
ExampleCXF.class.getClassLoader());
super.start();
}finally {
Thread.currentThread().setContextClassLoader(cl);
}
}
@Override
public void stop() throws Throwable {
super.stop();
logger.debug("Going down.");
}
/**
* Add routes to the CAMEL context.
*/
@Override
public void configure() throws Exception {
super.configure();
from(CXF_RS_ENDPOINT_URI).process(new Processor() {
public void process(Exchange exchange) throws Exception {
Message inMessage = exchange.getIn();
// Get the operation name from in message
String operationName =
inMessage.getHeader(CxfConstants.OPERATION_NAME, String.class);
if ("getCustomer".equals(operationName)) {
String httpMethod =
inMessage.getHeader(Exchange.HTTP_METHOD, String.class);
if(!"GET".equals(httpMethod)) {
throw new IllegalAccessException("Get a wrong http
method");
}
String path = inMessage.getHeader(Exchange.HTTP_PATH,
String.class);
// The parameter of the invocation is stored in the body of
in message
String id = (String) inMessage.getBody(String.class);
if ("/customerservice/customers/126".equals(path)) {
Customer customer = new Customer();
customer.setId(Long.parseLong(id));
customer.setName("Willem");
// We just put the response Object into the out message
body
exchange.getOut().setBody(customer);
} else {
if ("/customerservice/customers/123".equals(path)) {
// send a customer response back
Response r = Response.status(200).entity("customer
response back!").build();
exchange.getOut().setBody(r);
return;
}
if ("/customerservice/customers/456".equals(path)) {
Response r = Response.status(404).entity("Can't
found the customer with uri " + path).build();
throw new WebApplicationException(r);
} else {
throw new RuntimeCamelException("Can't found the
customer with uri " + path);
}
}
}
if ("updateCustomer".equals(operationName)) {
if(!"header1;header2".equals(inMessage.getHeader("test"))) {
throw new IllegalAccessException("Get a wrong customer
message header");
}
String httpMethod =
inMessage.getHeader(Exchange.HTTP_METHOD, String.class);
if(!"PUT".equals(httpMethod)) {
throw new IllegalAccessException("Get a wrong http
method");
}
Customer customer = inMessage.getBody(Customer.class);
if(customer != null) {
throw new IllegalAccessException("Customer should not
be null");
}
// Now you can do what you want on the customer object
if(!"Mary".equals(customer.getName())) {
throw new IllegalAccessException("Get a wrong customer
name.");
}
// set the response back
exchange.getOut().setBody(Response.ok().build());
}
}
});
}
}

The ICustomerService it's just an interface containing all methods from the
original CustomerService and its JAX-RS annotations. This CustomerService has
been exposed as an OSGi component as follows:
<ipojo xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns="org.apache.felix.ipojo"
xsi:schemaLocation="org.apache.felix.ipojo
http://felix.apache.org/ipojo/schemas/1.4.0/core.xsd";>
<component classname="org.ow2.jonas.sample.jaxrs.impl.ExampleCXF"

</requires>
<callback transition="validate" method="start" />
<callback transition="invalidate" method="stop" />
</component>
<instance component="ExampleCXF" />
</ipojo>

I suspect this has something to do with setting the adequate resource classes
properly, but I'm kind of clueless right now.
