EJB Connector

Hi All,

I'm having problems (NullPointerException) invoking a  SessionBean
from Mule.

Environment:
 JDK: 1.5
 OS: Windows XP - Service Pack 2 (5.1, x86)
 jboss-4.2.2.GA

The SessionBean is an EJB 3.0 one:

package com.test1.model;

import javax.annotation.PostConstruct;
import javax.ejb.Stateful;
import javax.interceptor.Interceptors;

@Stateful(name="SessionEJB")

public class SessionEJBBean implements SessionEJBRemote , SessionEJBLocal {
    private String desc = null;
   
    public SessionEJBBean() {
       
   
    }
        public void setDesc(String desc) {
            this.desc=desc;
        }
       
        public String sayHello(String name) {
            return "hello  :"+desc+" "+name;
        }
       
        @PostConstruct
        public void onConstruct(){
            System.out.println("onConstruct est invoquée !!");
        }
}


The JNDI stuff is working ok (i'm not getting NameNotFoundException any more).
I can successfully invoke this EJB from a standalone client.
