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
