Weston M. Price commented on QPID-3625:
---------------------------------------
I have attached a patch QPID3625-XASession.patch that allows for setting the
ack mode for an XASession. This is need for JEE message listeners and JCA
adapters where the XATransaction is started/ended/comitted in the onMessage()
method. As a result, we need to be able to set the ackmode to
CLIENT_ACKNOWLEDGE so we can acknowledge the message in the onMessage
invocation rather than allowing the JMS client to do it after the method ends.
> XASessionImpl Incorrectly sets Session acknowledge mode to AUTO_ACKNOWLEDGE
> when it should be CLIENT_ACKNOWLEDGE

> When using distributed transactions (XA) message acknowledgement needs to
> occur prior to the XA transaction being started in order to consistently
> support the two phase commit protocol. In order for this to correctly occur,
> the XASessionImpl, a non-transacted Session (i.e. non JMS transacted session)
> should be configured to use CLIENT_ACKNOWLEDGE as this is the only mode that
> supports explicit message acknowledgement which again, is required to
> correctly participate in the distributed transaction.
