I have a sessionFactory and my webapp works fine in jetty. However, When I copy the war file and deploy into jboss, it is throwing the above exception. I checked through the code in AnnotationConfiguration and it is doing,
newListeners[length-1] = (PostInsertEventListener) searchEventListener;

Can someone tell me if i am missing something here? The sessionFactory is just an annotation based one (working perfectly fine in jetty)
