Error description

  • When using the WebSphere MQ Version 6 Resource Adapter within
    a J2EE 1.4 compliant application server, messages are not being
    rolled back if a message-driven bean's onMessage() method
    throws a runtime exception. The messages are being consumed
    instead.
    
    When the runtime exception is thrown from onMessage(), the
    following warning message will be seen in the application
    server's log file:
    
    MQJCA4004: Message delivery to an MDB failed. See the linked
    exception for details.

Problem summary

  • ****************************************************************
    USERS AFFECTED:
    This issue affects users of the WebSphere MQ Version 6 resource
    adapter.
    
    Platforms affected:
    All Distributed (iSeries, all Unix and Windows) +Java
    ****************************************************************
    PROBLEM SUMMARY:
    The WebSphere MQ Version 6 resource adapter swallowed up the
    RuntimeException thrown from the message-driven bean's onMessage
    () method, rather than allowing it to reach the application
    server. This meant that the server thought the message had been
    consumed successfully, and did not attempt to roll back the
    transaction in which the message was processed.
    

Problem conclusion

  • The resource adapter has been changed to allow any Runtime
    Exceptions thrown from onMessage() to propagate back up to the
    application server.
