The only exception that I see in the trace you gave us is thrown by the spec implementation jar. I'm not looking at the source for that code, but my guess would be that the failure is happening because of a classpath error, such that OpenJPA is not available in the classloader that is visible to the Persistence class. Could you post your persistence.xml file and any details about how your classloader structure is set up?
