Cannot get a simple EJB 3 working

Question

Hi all !
I'm porting an older EJB 1.1 application to Weblogic 10.3. I'm upgrading the EJBs to EJB 3.0, for example the following:
@Stateless(mappedName = "ServiceSessionManager")
@Remote()
public class ServiceSessionManagerBean implements ServiceSessionManager {
Once deployed I have observed two entries in the JNDI tree:
ServiceSessionManager#irma
irma-ejbirma-ejb_jarServiceSessionManagerBean_ServiceSessionManager
However, trying to look up any of the two bindings results in an exception :
#1
ServiceSessionManager objServiceSessionManager = (ServiceSessionManager) ctx.lookup("ServiceSessionManager#irma");
java.lang.ClassCastException: weblogic.corba.j2ee.naming.ContextImpl cannot be cast to irma.ejb.serviceSessionManager.ServiceSessionManager
*     at irma.serviceLocator.ResourceLocator.remoteService(ResourceLocator.java:106)*
*     at irma.loginClient.LoginGUI.loadProfile(LoginGUI.java:287)*
#2
ServiceSessionManager objServiceSessionManager = (ServiceSessionManager) ctx.lookup("irma-ejbirma-ejb_jarServiceSessionManagerBean_ServiceSessionManager");
java.lang.ClassCastException: irma.ejb.serviceSessionManager._ServiceSessionManagerBean_6bu45c_ServiceSessionManagerIntf_Stub cannot be cast to irma.ejb.serviceSessionManager.ServiceSessionManager
I'm running the cllient using Sun JDK 1.6.20 and adding in the classpath wlclient.jar and the Server Project as well.
Any Help
Thanks
Frank

Hi Jay,
I've added deployment descriptors as suggested but now I get the following error:

Do you think this error can be caused by different JVM ? the server is running Java(TM) SE Runtime Environment (build 1.6.0_05-b13) while the client is running 1.6.20 ??
thanks again
