Albert Lee commented on OPENJPA-384:
------------------------------------

>From ConfigurationImpl.java

    public LogFactory getLogFactory() {
        if (logFactoryPlugin.get() == null)
            logFactoryPlugin.instantiate(LogFactory.class, this);
        return (LogFactory) logFactoryPlugin.get();   <<<<< CastCastException
    }

Are you sure weblogic.kodo.WebLogicLogFactory implements LogFactory?  From the class name, it sounds like it should but the code detects otherwise.

> 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:
