Spring + Hibernate +JTA - HibernateTransactionManager or JTATransactionManager

I want to Integrate Spring and H开发者_如何学Goibernate and use JTA for managing the transactions. I would also like to delegate transaction handling to the App server, which in my case is JBoss. I have a query regarding the configuration of the "transactionManager" bean in Spring:

1) Can we use HibernateTransactionManager and set the the properties hibernate.transaction.factory_class and hibernate.transaction.manager_lookup_class in hibernate.properties file? If not, why?

2) Or, should we use JTATransactionManager?

In option (2), do we still need to set the properties("hibernate.transaction.factory_class", "hibernate.transaction.manager_lookup_class") in hibernate.properties?

Thanks.

If you want to delegate to the appserver, you have to use JTATransactionManager to my knowledge, HibernateTransactionManager is not a JTA transaction manager.

PlatformTransactionManager implementation for a single Hibernate SessionFactory. Binds a Hibernate Session from the specified factory to the thread, potentially allowing for one thread-bound Session per factory. SessionFactoryUtils and HibernateTemplate are aware of thread-bound Sessions and participate in such transactions automatically. Using either of those or going through SessionFactory.getCurrentSession() is required for Hibernate access code that needs to support this transaction handling mechanism.
