    server endpoints, the following exception occurs:

Problem summary

  • ****************************************************************
    * USERS AFFECTED:  Users of WebSphere eXtreme Scale that have  *
    *                  multiple client applications that have the  *
    *                  embedded wsogclient.jar file and use IBM    *
    *                  eXtremeIO (XIO).                            *
    ****************************************************************
    * PROBLEM DESCRIPTION: More than one wsogclient.jar file in    *
    *                      an environment causes a                 *
    *                      ClassCastException exception when the   *
    *                      class is loaded in both applications.   *
    ****************************************************************
    * RECOMMENDATION:  Install WebSphere eXtreme Scale in the      *
    *                  WebSphere Application Server runtime        *
    *                  environment instead of embedding the client *
    *                  JAR file in the application.                *
    ****************************************************************
    When the embedded wsogclient.jar is loaded in a second
    application and calls for a class from eXtreme
    Scale, it uses an incorrect class that was loaded from the first
    embedded wsogclient.jar file.  These classes are not the same,
    since they have been loaded by different application class
    paths.
    

Problem conclusion

  • Corrected the class loader to accept both wsogclient.jar files
    embedded in multiple deployed applications.
