Denis Forveille commented on HHH-2124:
--------------------------------------
Same problem for us (Hibernate v3.2.5 + Seam 1.2.1 + WebSphere v6.1.0.13)
The problem is occuring because an exception occured during the beforeCompletion method triggered by the Transacation.commit(0 method, When the beforecompletion method throws an exception, the commit() method may throw a RollbackException signifying that instead of commiting the transaction, it rollbacked it. At that point it is illegal to perform a rollback or setRollbackOnly on a transaction which is already rollbacked and is not active anymore
I personally implemented another workaround:
- didnt' changed CacheSynchronization.java
- remove the "throw new UnsupportedOperationException()" line in WebSphereExtendedJTATransactionLookup.TransactionAdapter.setRollbackOnly() method
I don't know whcih workaround is better...
However i don't understand why most of the method of the WebSphereExtendedJTATransactionLookup.TransactionAdapter class throw UnsupportedOperationException() ... Maybe it should be better to delegate the calls to the underlying UserTransaction if it exists..
