    Some performance improvements for webservices in EJBs are
    implemented. The areas of improvement are classloader caching
    and reducing WebServiceContext updates.
    

Problem conclusion

  • The code is changed in the following areas to improve
    performance:
    1. WebServiceContext instances are not updated with a
    MessageContext for the current request unless needed
    for a proxy.
    2. A cached classloader from the AxisService object is used.
    
    The fix for this APAR is currently targeted for inclusion in
    fix pack 8.0.0.2.  Please refer to the Recommended Updates
