Error description

• The following error can be seen:
  
  8/23/11 11:32:50:781 EDT] 00000078 ConfigFileHel W   exception

  ------------------------------------------------
  
  Also - A second problem exists for this same APAR:
  
  After creating the server template from adminconsole and
  navigating through the created template server we are asked to
  save the configuration changes even when no changes are made.
  
  The following steps can be used to recreate the problem.
  
  1. Create a template from an existing server through the console
     panel Servers -> Server Type -> WebSphere application
     servers -> click on "Templates" button to create a
     server template using existing server.
  2. Save the configuration
  3. Navigate to Servers -> Server Type -> WebSphere application
     servers. Click on "Templates" and select the created
     server template to navigate into the template.
  4. When you navigate out of that page you are required
     to save configuration changes even if there were no changes.
     When you Review which files are going to be updated they are:
  templates / servertypes / APPLICATION_SERVER / hpelModel.xml
  templates / servertypes / APPLICATION_SERVER / server.xml

Problem summary

• ****************************************************************
  * USERS AFFECTED:  All users of the Administrative Console     *
  *                  managing Application Servers other than IBM *
  *                  WebSphere Application Servers.              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Error message reporting                 *
  *                      NullPointerException appears on the     *
  *                      Troubleshooting page for non-WebSphere  *
  *                      Application Servers                     *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Accessing Troubleshooting page for a non-WebSphere Application
  Server results in NullPointerException reported on the page
  and in the WrappedException for FileNotFoundException
  in the log files reporting hpelModel.xml file not being found.
  

Problem conclusion

• The fix ensures that if Application Server does not have a
  hpelModel.xml configuration file it is treated as an
  Application Server without HPEL capabilities.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.0.0.2.  Please refer to the Recommended Updates
