  • Closed as program error.

Error description

  • A shared library that is imported as an asset to a business
    level application (BLA) is not created and associated until
    the composition unit is started when the BLA is started.
    It is possible that an enterprise application archive (EAR)
    may depend on that shared library, but because both the EAR
    and shared library have the same starting weight by default,
    the shared library may be started after the EAR has started.
    This means that the EAR cannot load classes from the shared
    library until the BLA is restarted.

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  All users of IBM WebSphere Application      *
    *                  Server V7.0                                 *
    ****************************************************************
    * PROBLEM DESCRIPTION: When BLA shared libraries and EARs      *
    *                      have the same starting weight, it is    *
    *                      possible for the shared libraries to    *
    *                      be started and created after the EAR    *
    *                      application that depends on it.         *
    ****************************************************************
    * RECOMMENDATION:                                              *
    ****************************************************************
    The server runtime starts all BLA composition units with the
    same starting weight at the same time - regardless of declared
    dependencies between assets such as BLA EAR assets depending
    on BLA shared library assets.
    

Problem conclusion

  • This APAR resolves this problem by starting BLA shared library
    assets before BLA EAR applications when both have the same
    starting weight.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 7.0.0.17.  Please refer to the Recommended Updates
