I have NOT set the transaction to rollback only in the code. I guess its set by default.I want to change it and not set it to rollbackOnly. Also, I am explicitly calling commit() after the transaction. Why is it that i am still getting this exception? How do i ensure that the transaction gets committed?

Answer 1

Solved the issue!! Here is what worked for me:

1. Open the Web Deployment Descriptor
2. Select the Servlet which initiates the transaction.
3. For the Servlet, seletec the Websphere Extensions > Local Transaction.
4. Set the Resolver as "ContainerAtBoundary" and Unresolved Action: Rollback.
5. Save and RePublish.

Voila...I can commit the transaction now!!
