Thanks Mike. I included openjpa-1.2.1.jar in my client app and everything works great.

The short answer is that the client needs to have access to openjpa-1.2.1.jar so it can load the proxy classes. The larger question is whether OpenJPA should (or could) serialize to a non-proxy type to prevent this problem. I don't see the answer in the previous thread, but some additonal markmail or nabble searching may find it.
