After clustering Portal, all ConfigEngine scripts end with a "NullPointerException"

Troubleshooting


Problem

After clustering IBM® WebSphere® Portal v6.1, all ConfigEngine scripts end with a "NullPointerException" regardless of whether or not you receive a BUILD SUCCESSFUL.

Symptom

This error message will only display in the console window where you ran the ConfigEngine script and will not log anywhere.The full message is:

=================================

Cause

Required files were not copied over to the Deployment Manager prior to clustering. In the Information Center instructions for setting up the Deployment Manager, you are required to run a ConfigEngine script:

    ConfigEngine.bat collect-files-for-dmgr

This script collects the following files:
    AppServer/lib/wkplc.comp.registry.jar
    AppServer/lib/wp.wire.jar
    AppServer/plugins/com.ibm.ws.portletcontainer.deploytask_6.1.0.jar
    AppServer/profiles/Dmgr01/config/.repository/metadata_wkplc.xml
Failure to copy these files to the corresponding locations in your DMGR server, in particular the com.ibm.ws.portletcontainer.deploytask_6.1.0.jar file, will cause this exception to occur after every ConfigEngine script you execute.

NOTE:This failure will not cause any functional problems nor will it specifically cause a ConfigEngine script to fail. If you receive a BUILD FAILED and this exception occurs, this exception has nothing to do with why the ConfigEngine script failed.

Resolving The Problem

To prevent this error from displaying, follow these steps:

1. On the Portal node, run the following ConfigEngine script:

    ConfigEngine.sh|bat collect-files-for-dmgr

2. Extract the collection to some temporary directory. You should get a file structure that includes the following:
    AppServer/lib/wkplc.comp.registry.jar
    AppServer/lib/wp.wire.jar
    AppServer/plugins/com.ibm.ws.portletcontainer.deploytask_6.1.0.jar
    AppServer/profiles/Dmgr01/config/.repository/metadata_wkplc.xml

3. Ensure that the four files listed in Step 2 are copied to your DMGR.

4. Restart the DMGR
