EJB question

[Kit]

Hi all

I am trying to build a servlet client to look up an ejb.

But, i got the following error.


500 Internal Server Error

java.lang.ClassCastException: CartHome_StatefulSessionHomeWrapper1
        at
javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java, Compiled
Code)
        at testCart.doGet(testCart.java, Compiled Code)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java,
Compiled Code)
        at javax.servlet.http.HttpServlet.service(HttpServlet.java,

        at com.evermind.server.http.d5.rw(JAX)
        at com.evermind.util.f.run(JAX, Compiled Code)



this is what i did to do the look up.

  
final Properties properties = new Properties();

properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.ApplicationClientInitialContextFactory");
                        
properties.setProperty(Context.PROVIDER_URL,"ormi://localhost/ejbsamples");
                       
properties.setProperty(Context.SECURITY_PRINCIPAL,"username");

properties.setProperty(Context.SECURITY_CREDENTIALS, "password");


Context context = new InitialContext(properties);

                        
Object homeObject = context.lookup("MyCart");

                        
CartHome home = (CartHome)PortableRemoteObject.narrow(homeObject,CartHome.class);

                        
Cart cart = (Cart)PortableRemoteObject.narrow(home.create(), Cart.class);



Can anyone tell me why it failed ?

Thanks a lot.
