Remove anything from your constructor in Account. You have a circular dependency. And Hibernate uses the public no args consructor for its beans

1. HibernateUtil loads
2. That forces the static to run buildSessionFactory
3. Hibernate instantiates Account via no args
4. That in turn calls HibernateUtil.....

Trust me: public no arg constructor with NO code, except POJO setters. Nothing else.
