Ok sorry, I jumped the last part of your answer... That could be it because that thing of lookup is not very clear to me.

My interface :

  | package org.eu.nuadu.cuore.bd.query; 
  | import datamodel.DAO.SystemUser;
  | 
  | public interface QueryInt {
  | public abstract SystemUser AuthenticateUser(String uid, String pwd);
  | }
  | 

And code which uses the EJB:

  | package ws.process;
  | 
  | import org.eu.nuadu.cuore.bd.query.Query;
  | import org.eu.nuadu.cuore.datamodel.DAO.SystemUser;
  | 
  | public class Authentication {
  | 	
  | 	public void authenticate(){
  | 					
  | 		SystemUser _SystemUser = new Query().AuthenticateUser("july","1234");
  | 		if (_SystemUser != null)
  | 			System.out.println(_SystemUser.getIdSystemUser());		
  | }
  | }
  |
