Cause

This is a known issue cause by two old data tool plugins that existed in "deploytools/itp/plugins/" directory.
Since a new version of the faulty data tools plugins were installed in WebSphere Application Server [7.0.0.13, 7.0.0.19] range:

  • com.ibm.datatools.core_3.0.101.v200811190853.jar
  • org.eclipse.datatools.modelbase.sql.query_1.0.1.v200811050430.jar

Resolving The Problem

Update WebSphere Application Server to at least 7.0.0.21 where this issue was fixed.
Note: After upgrading to WAS 7.0.0.21 you may need to clear the Eclipse OSGI cache as per instructions provided in the following technote:

http://www-01.ibm.com/support/docview.wss?uid=swg21382867

WORKAROUND:

Remove the old data tool plugins:

  1. Navigate to "<WAS install Dir>/deploytools/itp/plugins/" directory

  2. Back up the following jar files:
    • com.ibm.datatools.core_3.0.101.v200811190853.jar
    • org.eclipse.datatools.modelbase.sql.query_1.0.1.v200811050430.jar

  3. Remove the jar files from step #2 in the " <WAS install Dir>/deploytools/itp/plugins/" directory

  4. Navigate to "/opt/IBM/WebSphere/AppServer/deploytool/itp/configuration"

  5. Back up the "/configuration" directory

  6. Delete all the files and directories within "/configuration" directory

    Note: Except "config.ini" if present.

  7. Run wcbd-build again and verify the result.
