Error description
While processing a message, a message-driven bean application throws an exception which results in that message being rolled back by the WebSphere MQ Resource Adapter. When the message-driven bean application processes subsequent messages, the WebSphere MQ Resource Adapter incorrectly rolls messages back even if the application does not throw an exception during message processing. . Additional keywords: roll back rollback

Problem summary
**************************************************************** USERS AFFECTED: This issue affects users of: - The WebSphere MQ V7 Resource Adapter. - The WebSphere Application Server V7 WebSphere MQ messaging provider. - The WebSphere Application Server V8 WebSphere MQ messaging provider. who have Message Driven Beans that may throw an Exception during their processing in the onMessage() method. Platforms affected: MultiPlatform **************************************************************** PROBLEM SUMMARY: When an exception is thrown by a Message Driven Bean (MDB) throws, the result is that the associated MDB transaction is marked as a failure, which leads to the transaction being rolled back. Depending on the sequence of actions performed by the Transaction Manager, the flag to indicate that the transaction was marked as a failure was not always reset when using the MQ V7 Resource Adapter. The result of this was that subsequent transactions were also rolled back instead of being committed, even when no failure occurred during that subsequent MDB processing.
Problem conclusion
The WebSphere MQ V7 Resource Adapter has been changed to reset the affected flag to its default value in all circumstances. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.0 7.0.1.12 v7.1 7.1.0.5 v7.5 7.5.0.4 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
