JBossCache with Hibernate Transaction

[aashishvora]

Hello,
I am trying to develop an application with Hibernate for persistence, Spring for transaction demarcation. I am also using JBossCache for data replication across 2 members in a cluster.

The requirement is that the data should not be replicated unless the transaction is completed. Hence JBossCache is configured to use transaction and it is working fine as long as JBoss JTA transaction is being used.

With the change in requirement, we are being asked to use Hibernate's transaction management. I am not sure how to integrate JBossCache with Hibernate's TM. Is it possible to do so?

Any help is greatly appreciated.

JBoss Cache requires use of a JTA transaction manager; doesn't have to be JBoss', but must be JTA. Hibernate transactions are not JTA.

Thanks a lot for quick response.

Make sure both JBoss Cache and Hibernate are configured to use the same TM and then use the Hibernate transaction interfaces to begin/commit/rollback your transactions.

Behind the scenes, both interfaces delegate transaction orchestration to the TM configured; just make sure they are both configured to use the same TM.

Brian,

You can use JTA TMs with Hibernate:

Yep, I know. I interpreted the question as meaning he didn't want to use JTATransactionFactory as the hibernate.transaction.manager_lookup_class, but rather wanted JDBCTransactionFactory. But as I reread it I see that's not what he said. Thanks for clarifying :)

Just one more question, will JBossCache work if I configure with JTA but the Transaction Management suports only one-phase and does not support 2 Phase(XA) protocols.

Your understanding of my problem is correct. I wanted to use JDBCTransactionFactory as my transaction lookup class. And as I understood it, cannot be done with JBossCache.

Just to clarify further, I still have Hibernate participating in the same transaction with the help of non XA datasource, hence I have two transactional resource(Hibernate and JBossCache) and both are committing or rolling back together.

Thanks
