Dies,

thanks for your kind help. No deployment descriptor is used (want to get
rid of that now using EJB 3.0...).

This is the remote interface (extends EJBObject was added since spec
told me to do):

@Remote
public interface HelloServerRemote extends EJBObject {
    String greeting() throws RemoteException;
}

This is the remote home interface:

public interface HelloServerRemoteHome extends EJBHome {
    public HelloServerRemote create() throws RemoteException,
CreateException;
   // Spec says, in this particular case, I do not have to implement
ejbCreate in the client, since it is SLSB.
}

This is the bean class:

@Stateless
@RemoteHome(HelloServerRemoteHome.class)
@Remote(HelloServerRemote.class)
public class HelloServer {
    public String greeting() {
        return "Hello - Test";
    }
}

I cannot see any fault here.

Thanks
Markus
