Not sure, if you can manage to catch RollbackException in the case of
CMT. Transaction commit/rollback happens after the business method has
finished its execution, so you can intercept. What you can do is,
implement SessionSynchronization call back, which will tell you whether
transaction has been committed or rolled back.
