Re: New Warnings in Managed Environment with RC7
Hi Gary, Gary wrote: Armin: Thanks again for your help. Do you mean that I should close the PB before the commit is called? yep! If so, I tried it, with the same results. I am still confused as to what the correct ordering of PB opens/closes and commit/rollback operations are. This all worked great before I moved to RC7. I can't remember if I was on RC5 or RC6 before... we changed the internal connection handling between rc6 and rc7, because JBoss always warn about unclosed connections in JTA tx, thus we close the used connection handle on PB.close() call on the PB handle instance, but keep internal the real used PB instance. The PB.close() call have to be invoked before the tx commits. This means if container managed/declarative tx is used before the method quit, if bean managed/programmatically tx is used before the UserTransaction.commit() was called. On the commit of the JTA transaction OJB was notified by the tx to do the real cleanup and close of the real used PB instance. regards, Armin Gary --- Armin Waibel [EMAIL PROTECTED] wrote: Hi Gary, Gary wrote: No, I first commit or rollback the transaction, and then close the PB. ok, so I think this is the reason for the failure.

Re: New Warnings in Managed Environment with RC7
It appears as though beginTransaction() is called on the given PersistenceBroker instance when it is created. Then, when a JTA commit operation occurs, it tries to release the connection (as shown in the stack trace below) but thinks that a local transaction is active. I assume that with a JTA transaction, no local transaction should be involved. I see there were changes in this (these messages appear new). Is anyone else seeing this behavior?
