[jboss-user] [JBoss jBPM] - JBPM - EBJ

Hello
I'm a newbie to JBPM and i'm trying to use ejb stub client in a Action Handler.
I've created a very simple stateless session EJB 3.0 that replicates a  string through a remote interface.
I'm trying to instantiate this stub with the usual :

  | 		try {			
  | 			InitialContext ctx = new InitialContext();
  | 			kp = (dumKp) ctx.lookup("dumKP/dumKpBean/remote");
  | 		} catch (Exception e) {
  | 			System.err.println("Cannot find dumKP/dumKpBean/remote");
  | 			e.printStackTrace();
  | 		}
  | 
  |  
provided on top of the execute methode.
I'm facing a lot of pb .... 
Even though i've packed the interface dumpKp in a client jar
added to the jbpm project (in deployment too), when running i got :

After a look to various forum i got an hint regarding the fact that a Security Manager was missing,
So i added one and got Hibernate Transaction Error.

...... 
To make a long story short, does anybody knows if it is 
simply possible to use ejb stub in a jbpm workflow
and if yes is there some docs links somewhere.
......
Thanx to all ....
