Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of the default messaging provider for *
    *                  IBM WebSphere Application Server Version 7.0*
    ****************************************************************
    * PROBLEM DESCRIPTION: Messages sent by IBM Message Service    *
    *                      (XMS) clients cannot be received by     *
    *                      XMS or JMS applications due to a        *
    *                      MessageEncodeFailedException            *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    A com.ibm.ws.sib.mfp.MessageEncodeFailedException occurs
    as a result of a java.lang.NullPointerException within the
    messaging engine, when it attempts to deliver the message sent
    by XMS to another application over a network.
    
    This prevents messages sent by XMS clients from being received
    by any application that connects to the messaging engine over
    a network (including XMS clients).
    
    The exceptions are caused by the WebSphere Application Server
    Version 7.0 code assuming that messages sent by the XMS
    client contain a mandatory field within the internal
    representation of the message.
    The XMS client does not set this field, and a
    NullPointerException occurs. Previous versions of WebSphere
    Application Server tolerated the missing field in this scenario.
    

Problem conclusion

  • The fix for this APAR updates the default messaging
    provider code in WebSphere Application Server Version 7.0 to
    tolerate the missing field when delivering messages to
    applications over a network.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.9.  Please refer to the Recommended Updates
