HI Wolfgang,

Thanks a lot, I could see deployed EJBs in jmx-console. Now face problem with client -

*My Code* :

          Object obj = ServiceLocator.getEJB(AuthenticationBean.RemoteJNDIName);
            System.out.println("EJB Look up successfull ");    
            
            AuthenticationRemote authEjb = (AuthenticationRemote)PortableRemoteObject.narrow(obj, AuthenticationRemote.class);

*Error* :
