Abstract: The WebSphere classloader was not correctly picking up a jar file that was referenced by an EJB module's manifest.

Description/symptom of problem: 

The WebSphere classloader was not correctly picking up a jar
file that was referenced by an EJB module's manifest.
For example:
WAR -> EJB1 -> Dependent JAR
EJB2 -> EJB1
The above resulted in the dependent jar being improperly
handled resulting in ClassCastExceptions

   

Local Fix: 


Directions to apply efix:

1) Create temporary "efix" directory to store the zip/tar file:
             AIX: /tmp/WebSphere/efix
   Solaris/Linux: /tmp/WebSphere/efix
         Windows: c:\temp\WebSphere\efix

2) Copy zip/tar file to the directory

3) Unzip/untar the file

4) Shutdown WebSphere

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

6) Restart WebSphere

7) The temp directory may be removed but the zip/tar file should be saved.  Do not remove 
   any files created and stored in the <WASHOME>/WebSphere/AppServer/efix/PQ54151 directories.
   These files are required if an efix is to be removed.



Directions to remove an efix:

NOTE:  EFIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE AN EFIX UNLESS
       ALL EFIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY REAPPLY ANY REMOVED EFIX.

Example:  If your system has efix1, efix2, and efix3 applied in that order and efix2 is to be
          removed, efix3 must be removed first, efix2 removed, and efix3 re-applied.


1) Change directory to the efix location (<WASHOME>/WebSphere/AppServer/efix/PQ54151).

2) Shutdown WebSphere

3) Run the backup jar file with the following command:
   java -jar PQ54151_eFix_AEsServer_AEServer_backup.jar

4) Restart WebSphere

5) To enable view the additional information provided below.


Directions to re-apply an efix:

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