Answer 1

RESOURCE_LOCAL only applies to JPA EntityManager, not to a Hibernate SessionFactory. Hibernate’s Spring integration is rather smoother than it is with JPA, and so the only thing that determines the transactional behaviour is which transaction manager you use with it (either HibernateTransactionManager or JtaTransactionManager). It’ll work with either one without you having to explicitly configure the SessionFactory.
