ClassCastException when trying to load OpenJPA 1.0.0 based webapp in WebLogic 10

                 Key: OPENJPA-384
             Project: OpenJPA
          Issue Type: Bug
    Affects Versions: 1.0.0
         Environment: WebLogic 10
            Reporter: Simon Droscher

I am trying to deploy a web application which uses OpenJPA 1.0.0 into a WebLogic 10 environment.
The application deployment (and subsequent startup) fails with the following error:

{code}java.lang.ClassCastException: weblogic.kodo.WebLogicLogFactory

There doesn't seem to be any details or documentation on running apps based on newer versions
of OpenJPA under WebLogic 10 (which packages OpenJPA 0.9.7 as part of Kodo).
