PROBLEM SUMMARY

USERS AFFECTED:
Users of IBM WebSphere Application Server
version 6.0.2 at level 6.0.2.19 or 6.0.2.21.

PROBLEM DESCRIPTION:
Performing a save operation after
uninstalling an application throws a
NullPointerException.

RECOMMENDATION:
None

After uninstalling an application, attempting to save
changes causes a NullPointerException to be thrown.

During a save operation for application related files, the name
of the application is retrieved from the URI of the changed
files.  Application delta file URIs will have a ".ear" suffixed
to the application name.  While retrieving the application name,
the ".ear" suffix is not truncated.

Since the application name is retrieved with the ".ear" suffix
we interpret it as a different application and try to handle it
separately, which leads to a NullPointerException.

PROBLEM CONCLUSION:                                             
The code was changed to properly retrieve the application name  
from the application file URIs.                                 
                                                                
The fix for this APAR is currently targeted for inclusion in    
fixpack 6.0.2.23.

http://www-1.ibm.com/support/docview.wss?rs=180&uid=swg21205400

1) Copy PKxxxxx.pak file directly to the maintenance directory

2) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that maintenance is being applied to.

* YOU MAY REAPPLY 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) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that uninstall is being run against.

2) Start Update Installer

3) Enter the installation location of the WebSphere product you want to remove the fix.

4) Select  "Uninstall maintenance package" operation.
