Abstract:  Fix largebranch JSP compilation failure on WAS4.0.7

Description/symptom of problem:  Servlets in WebSphereŽ Application Server can throw exceptions during JSP compilation when the largebranch option is enabled in the JSP compiler. This is because the JSP compiler is not threadsafe. 


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.  It is important that you perform a controlled and complete shutdown of the server to ensure that all transactions have completed, before installing the fix.

4)Create a <WASHOME>/Fix directory if one does not already exist

5) Run the jar file with the following command answering questions/prompts as they appear:
   java -jar <jarfile name> -backupJar <WASHOME>/Fix/<jar file name>_backup.jar

6) Restart WebSphere

7) 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 directory.
   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 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) Change directory to the fix location (<WASHOME>/Fix).

2) Shutdown WebSphere

3) Run the backup jar file with the following command:
	java -jar <backup_fix#>

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.
