Abstract: java.lang.NoClassDefFoundError received from JNDI lookup

Description/symptom of problem:

     When executing a JNDI lookup on an object bound as a
     java.io.Serializable, javax.naming.Reference, or
     javax.naming.Referenceable, processing may fail because a class
     required to instantiate the returned object cannot be found.


Directions to apply e-fix:

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) Shut down WebSphere

5) Run the jar file with the following command answering questions/prompts
   as they appear:

      java -jar PQ51386/v4.0.1/PQ51386_eFix.jar

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/<e-fix> directories.  These files are
   required if an e-fix is to be removed.


Directions to remove an e-fix:

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 e-fix1, e-fix2, and e-fix3 applied in that order
          and e-fix2 is to be removed, e-fix3 must be removed first, e-fix2
          removed, and e-fix3 re-applied.


1) Change directory to the e-fix location
   (<WASHOME>/WebSphere/AppServer/eFix/PQ51386).

2) Shut down WebSphere

3) Run the backup jar file with the following command:

      java -jar PQ51386_eFix_backup.jar

4) Restart WebSphere


Directions to re-apply an e-fix:

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