[jboss-user] [EJB 3.0] - Re: java.lan.ClassCastException when casting to remote bean

[manemannen]

Thanks for the replies!

Yes, I figured that it was the class loading issue after reading a bunch of other posts (before posting the original topic). Sadly, I do not know how to remedy the problem.

When I look in the unpacked war I can see the interfaces the simple-ejb.jar file and there is another one unpacked in the .ear directory, The interface is identical although defined in two places and as far as I understand loaded by different class loaders - which is the root problem.

I tried your suggestion Wolfgang but can't see how it would help (I got the same exception). The problem is still the same.

Object o = ctx.lookup("simpleserver/" + SimpleStatefulBean.class.getSimpleName() + "/remote");
  | SimpleStatefulBeanRemote x = (SimpleStatefulBeanRemote) PortableRemoteObject.narrow(o, SimpleStatefulBeanRemote.class);

  | 08:48:36,062 ERROR [STDERR] 	at javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:137)

Could you give me some pointers on how to proceed?
