Hi,

I am using hibernate 2.1.8.My application is deployed on WAS 6.0

I am using query caching and second level caching.Cache concurrency strategy is READ ONLY.
Appliaction is running fine for 1 week.But after that following exception is comming :

net.sf.hibernate.TransactionException: could not register synchronization with JTA TransactionManager
at net.sf.hibernate.impl.SessionImpl.connect(SessionImpl.java:3369)
at net.sf.hibernate.impl.SessionImpl.connection(SessionImpl.java:3333)

I am working on the same.It will be of great help if someone can tell why it is happening.It is very critical.

The very possible cause of this Exception is the Transaction is not active(may be is timed out n is marked for ROLLBACK) and the application is attempting to join to the transaction.

Thanks for the quick response...

What you are saying is correct..But i am using a container managed transaction..when a new request comes container starts a new transaction..
In my code i am not providing any transaction demarcation...I am not beginning the transaction..neither committing it....

The application is working fine on WAS 5. But when deployed on WAS 6 the problem is occuring..

Is there some integration problem with WAS 6.0..
