CMVC Defect:  PQ75451

Byte size of APAR:  1069843

Abstract:  When using a client on AEs, the client will not WLM to a WAS AE 4.0 or WAS 5.0 cluster.

Description/symptom of problem:  

A 4.0 AEs client bootstrapping to the WAS 4.0 AE Admin Server or a WAS 5.0 node agent or "foreign" cluster member.
Fails with NPE
In this scenario the WLM code also gets the request to route the request before any cluster information has been resolved.  Thus, it attempts to resolve to the AdminServer to get the information directly.  The AdminServer does not exist and messages WWLM0028 and WWLM0020 are logged.  An internal variable is not set in this path (and should not be) which shortly thereafter gets dereferenced (the bug) causing the NullPointerException in the EJSRepositoryClient.



Directions to apply fix:  

1) Create temporary "Fix" directory to store the jar file:
            UNIX: /tmp/WebSphere/Fix
         Windows: c:\temp\WebSphere\Fix

2) Copy jar file to the directory

3) Shutdown WebSphere

4) Run the jar file with the following command answering questions/prompts as they appear:
   java -jar <jar file name>

5) Restart WebSphere

6) The temp directory may be removed but the jar file should be saved.  Do not remove 
   any files created and stored in the <WASHOME>/Fix/PQ75451 directories.
   These files are required if a Fix is to be removed.





Directions to remove fix:  

NOTE:  FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE A FIX UNLESS
       ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY RE-APPLY ANY REMOVED FIX.

Example:  If your system has Fix1, Fix2, and Fix3 applied in that order and Fix2 is to be
          removed, Fix3 must be removed first, Fix2 removed, and Fix3 re-applied.


1) Change directory to the Fix location (<WASHOME>/Fix/PQ75451).

2) Shutdown WebSphere

3) Run the backup jar file with the following command:
   java -jar PQ75451_Fix_backup.jar

4) Restart WebSphere





Directions to re-apply fix:  

Follow the instructions for applying a Fix.  If the backup files still exist (from the 
previous Fix application), you will be prompted to overwrite.  Answer "yes" at the overwrite 
prompts.
