JAX-WS in JBoss AS7, getting cast exception

Question

I created a simple webservice with JAX-WS, but I expecting a anoying issue.

My webservice code is something like this:

@WebService
public class UpdateList implements IUpdateList {

    public UpdateList() {
    }

    @Override
    public Collection<Long> getFrom(Long version) {
        System.out.println("test");
        return new ArrayList<Long>();
    }

}

I generated the client code with wsimport and created a simple main for it:

public class App {

    public static void main(String[] args) {
        System.out.println(new UpdateListService().getUpdateListPort().getFrom(183L));
    }
}

But, when I run it, I got a unexplainable class cast exception:

Exception in thread "main" java.lang.ExceptionInInitializerError
    at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(Unknown Source)
    at com.sun.xml.internal.ws.client.sei.SyncMethodHandler.invoke(Unknown Source)
    at com.sun.xml.internal.ws.client.sei.SEIStub.invoke(Unknown Source)
    at $Proxy29.getFrom(Unknown Source)
    at com.test.App.main(App.java:8)
Caused by: java.lang.ClassCastException: com.sun.xml.bind.v2.runtime.JAXBContextImpl cannot be cast to com.sun.xml.internal.bind.api.JAXBRIContext
    at com.sun.xml.internal.ws.fault.SOAPFaultBuilder.<clinit>(Unknown Source)
    ... 5 more

Then I just realized that it could be some dependency conflict, so I run mvn dependency:tree, and it's clean, my only deps are hibernate, guava, guice and jaxws-rt. (you can see that in my webservice example, it is not using any of cited dependencies, but I'll do it soon, when I fix this issue).

Well, the complete list, for client:

I end this thinking that's some config or jar file missing in my jboss.. I do some research, but not found anything relevant.

Someone already passed througt this? Any suggestion? Thanks

Answer 1

It looks like you're bundling a JAXP implementation, com.sun.xml.bind:jaxb-impl:jar:2.2.6:compile. Try changing the scope to <scope>provided</scope>. Same for the com.sun.xml.ws:jaxws-rt:jar:2.2.6-2:compile.

In fact, most of those should be provided.
