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).

Hi,
The EJB connector should not have to be explicitly referenced on the endpoint (at least, not according to http://mule.mulesource.org/display/MULE2USER/EJB+Transport) unless you have more than one connector declared.

hi,
I modified the endpoint but the problem still exists. <endpoint address="ejb://localhost:1099/SessionEJB/remote?method=sayHello2"/> Mule EJB provider can only invoke EJB 2.x methods. a new provider (http://www.muleumo.org/display/EJBTHREE/Home) This provider supports invoking EJB3.0 methods. But i don't know how to implement this ? just copying the jar file ti MULE_HOME/lib/user ? Thanks in advance. Nabil

Hi,
If you need EJB3, then that transport is the one you need. Unfortunately, it looks like there hasn't been much work on it. You could take a look at the source (if any) http://www.mulesource.org/display/EJBTHREE/Source and perhaps extend it yourself. Or you could try and subscribe to their mailing list and see if there's any info about it. http://admin.muleforge.org/projects/ejb3-transport/lists HTH Antoine Borg, Senior Consultant | Tel: +32 28 504 696 ricston Ltd., BP 2, 1180 Uccle, Brussels, BELGIUM email: antoine.borg@... | blog: blog.ricston.com | web: ricston.com -----Original Message----- From: NabiL [mailto:elaomari.nabil@...] Sent: Friday, September 26, 2008 11:26 AM To: user@...
