I'm using the standard Hibernate and Hibernate JPA that comes with Netbeans 7.2.1. (Hibernate 3.2.5) I have mapped out my files, written junit tests which complete successfully. I'm now trying to implement Hibernate in out web environment which is Tomcat. When I execute the following statement:

Session session = HibernateUtil.getInstance().getCurrentSession() it fails when it executes sessionFactory = new AnnotationConfiguration().configure().buildSessionFactory();

This is the same HibernateUtil class that I use in the Junit tests. Here is some of the output and trace. Any help would be appreciated.
