  ****************************************************************
  * PROBLEM DESCRIPTION: Due to a programming error, an NPE      *
  *                      occurs when the application uses a      *

  * RECOMMENDATION:                                              *
  ****************************************************************
  Due to a programming error in the IBM JSF Portlet Bridge, an
  NPE occurs when the application uses a JSP instead of an XHTML
  facelet.
  

Problem conclusion

• It should be noted that use of JSPs instead of facelets
  for the view is back-level JSF technology and is supported for
  compatibility reasons only. Customers should be encouraged to
  move their applications to facelet technology.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 9.0.5.0.  Please refer to the Recommended Updates
