My code is executing on standalone Tomcat but its giving me a strange exception on jboss.

Configuration cfg = new Configuration();

SessionFactory factory = cfg.configure().buildSessionFactory();
Session sessions = factory.openSession();

Transaction t = sessions.beginTransaction();

sessions.save(c);
sessions.save(p);
t.commit();
sessions.close();

Plz I dont have any clue about that, and im stuck in the middle of project.
