Configuring JTA to repair transactional issues

Most likely since the move to blitz, the transactional
security of service methods has been brittle if not
non-existent. The difference is most likely the use of
JTA in the container (JBoss).

One vital key to making this work was the transaction
factory_class property on the Hibernate SessionFactory?.
