APAR status

• Closed as program error.

Error description

• Log factory class conflicts are causing problems accessing the
  admin console, if the same log factory class is loaded by
  another jar.
  The following message might be seen in the log:
  Error Message: javax.servlet.UnavailableException:
  SRVE0203E: Servlet [action]:
  org.apache.struts.action.ActionServlet was found, but is missing
  another required class.
  

Local fix

• To avoid class conflicts the respective classes can be placed in
  a shared library which is then associated with the applications
  that need it.

  org.apache.struts.action.ActionServlet was found, but is
  missing
  another required class.
  

Problem conclusion

• A configuration file was added in the class path of the
  console war to ensure that the console application only loads
  its respective commons logging class regardless of what's
  defined outside of it.
  
  The fix for this APAR is currently targeted for inclusion in
  fix pack 8.5.5.17 and 9.0.5.0.2.  Please refer to the
