I have few doubts.
1) Can the XA transactions can be manipulated just with JAVA MQ Base class.?
2) javax.transaction.xa.* & javax.sql.XADataSource; were actually JTA.?
pls give some light on this subject pls.

| The base Java classes allow WMQ to be transaction manager for an XA transaction involving WMQ and a supported database. For example, you could write code to consume a message and update a database table; if the database update failed, the transaction would be backed out and the message would be rolled back on to a queue. No external transaction manager is required (or, for that matter, supported). |

As far as I remember the only external TM's supported are
- Mainframe IBM TM's like CICS (IMS?) etc...
- WAS : Websphere Application Server (using J2EE and JTA)
- WebLogic (using J2EE and JTA)
I hope somebody from Big Blue can correct me and add a few more.

From base Java, none of the above 
With JMS it was WAS and WebLogic, as of last friday it's a bit different. |

We're trying to use XA-transaction with our JAVA code in the following way...
1) If we STOP the queue manager manually( to test), our server will continously listening, and when the Q-Mgr is active... will Re-connec t to the Quemanager and continue the transaction..
But the problem we're facing is that...
When we manually stop the Qmgr & try to re-connect it, the QMgr shows AMQ8041 & AMQ 7018,saying that the Process is not complete.!
How this scenario could be avoided.?
Or what are the points to take care,when we're using XA-Transaction.?
