Hi!

I'm currently working on a simple EJB application using EJB 3.0. One design goal is \
to not have any EJB-related code on the client - not even the remote interfaces! But \
for some reason, dynamic classloading does not work as expected.

The idea is to have a general (non-remote) interface (let's say "Calculator") that is \
extended by the remote interface (let's say "CalculatorRemote") that does not declare \
any additional methods. The implementation of the "CalculatorRemote" interface is the \
session bean "CalculatorBean". When packaging the client, it only contains the \
Calculator interface (and the client-implementation of course). But when I try to \
lookup the CalculatorBean inside the client, I get a "ClassNotFoundException: \
CalculatorRemote".

  | /* Calculator */
  | public interface Calculator {
  |   public int add(int a, int b);
  | }
  | 
  | /* CalculatorRemote */
  | @Remote
  | public interface CalculatorRemote extends Calculator { /* empty */ }
  | 
  | /* CalculatorBean */
  | @Stateless
  | public class CalculatorBean implements CalculatorRemote {
  |   public int add(int a, int b) { return a + b; }
  | }
  | 
  | /* client code */
  | ...
  | Calculator calc = (Calculator)ctx.lookup("CalculatorRemote");
  | int sum = calc.add(3, 5);
  | ...
  | 
Shouldn't the CalculatorRemote interface be dynamically loaded from the server? Is \
dynamic classloading enabled by default or do I have to change some configuration \
files on JBoss?

Thanks,
  Tex
