Using hibernate on ejb 2.X

I've created a simple application with ejb 2X and web module. App is packaged as EAR. I want to test hibernate on ejb, but i have some problems testing on ejb-module. Test on web module works fine and I can do CRUD operations with hibernate.

The problem is when I try list from Table.

The method test on EJB throws Exception

The code

SessionFactory sessionFactory = new Configuration().configure().buildSessionFactory();
Session session = sessionFactory.openSession();
java.util.List list = session.createQuery("from DatosIsla").list();

The Exception deploying app

 Session session = sessionFactory.openSession();
 //java.util.List list = session.createQuery("from DatosIsla").list();

Whats wrong?

I'm using eclipse helios jboss 3.2.8 jboss-tools

It seems to me that the hibernate libraries are not in the classpath of the application:

java.lang.NoClassDefFoundError: org/hibernate/Session

Check in your project configuration and your launcher, that the hibernate jars are referenced. Same to the ear, are the jars included. Also check that not multiple versions are deployed (from the application container as well as in the ear).
