2. Specification violation EJB3 JPA    seamframework.org

I think the way you configure it would be OK with JPA outside an application server, you should use a datasource instead. Moreover the Hibernate transaction factory class you chose talks about JTA, and you have to run within an application server to have JTA available, so I understand it expects a JTA datasource.
