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

[manemannen]

I get a ClassCastException when trying to cast to a remote interface of stateful session bean (for some reason it works for the stateless ones..). To really pinpoint the problem I made the easiest project possible.

At the server application I have the following bean

@Stateful
  | public class SimpleStatefulBean implements SimpleStatefulBeanRemote, SimpleStatefulBeanLocal {
  | 
  | 	public SimpleStatefulBean() {
  | 	}
  | 
  | 	@Override
  | 	public boolean isSimple() {
  | 		return true;
  | 	}
  | }

The remote interface looks like this:

@Remote
  | public interface SimpleStatefulBeanRemote {
  | 	public boolean isSimple();
  | }
  | 

On the client side I have a web application. It is running on the same JBoss AS but is not deployed in the EAR as the bean above. I created a servlet to access the bean. 
In the doGet methods of the servlet..

  | 	try {
  | 			Properties p = new Properties();
  | 			p.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
  | 			p.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
  | 			p.put("java.naming.provider.url", "localhost");
  | 			Context ctx = new InitialContext(p);
  | 			SimpleStatefulBeanRemote o = (SimpleStatefulBeanRemote) ctx.lookup("simpleserver/" + SimpleStatefulBean.class.getSimpleName() + "/remote");
  | 		} catch (Exception e) {
  | 			e.printStackTrace();
  | 		}

Now it does not work to cast it to the remote interface! I get the following error:

19:53:27,164 ERROR [STDERR] java.lang.ClassCastException: $Proxy90 cannot be cast to com.test.SimpleStatefulBeanRemote
