I found it!
The hibernate.cfg.xml parameters doesn't work, so you can remove them.
In order to make you hibernate aware of the listeners you can add them directly to the configuration.
Below the code:
AnnotationConfiguration configuration = new AnnotationConfiguration();
AuditEventListener auditEventListener = new AuditEventListener();
configuration.getEventListeners().setPostInsertEventListeners(new PostInsertEventListener[]{auditEventListener});
configuration.getEventListeners().setPostUpdateEventListeners(new PostUpdateEventListener[]{auditEventListener});
configuration.getEventListeners().setPostDeleteEventListeners(new PostDeleteEventListener[]{auditEventListener});
sessionFactory = configuration.buildSessionFactory();
Session s = sessionFactory.openSession();
....
Good luck,
