Dr. Jung, Thank your for your help. That was the problem. However, I can't really change the Javabeans since they are being created by XDoclet. Now, xdoclet 1.1.2's dataobjects conform to the JavaBeans spec - however 1.2.0cvs valueobjects do not. I need to use cvs' valueobjects because it creates getters and setters for my relationships. Unfortunately, is also adds some gets that don't have sets.
Sooo, it looks like I need to write my own serializers and deserializers. I see the docs at: http://xml.apache.org/axis/ , however my question to you is where do I put the de/serializer classes? In the .wsr?
