Error when using Toplink Ant tasks - Several [3] SessionLoaderExceptions

Question

Hi,
I'm trying to integrate toplink's session exports with my build process (Apache Ant). I've been working from the example here:
http://download.oracle.com/docs/cd/E14571_01/web.1111/b32441/mw.htm
My Ant init target and the session validation target are shown below:

When I turn on verbose mode in ant I can see more details of the error:

Help

The 3 errors shown above correspond to the 3 tags at the same level in the session.xml file. I have tested this validation process with a session.xml file generated from the workbench and that failed too. Since its a NoSuchMethodException it looks like my ant process isn't finding the oracle.toplink.tools.sessionconfiguration.XMLLoader class, but that is in toplink.jar which is in the class path.
Any help appreciated

Dear Arun,
The WLS server is the same for (integrated WLS and Production) . For JRF template I'm sure it is the same. I have deploy another application that used BC, and it work fine in production.
