JAXB generally doesn't like interfaces too much. In general, we
definitely suggest using concrete classes.
That said, one major issue is that your interface doesn't have setter
methods on it. There's no way there's any chance of it working without
that. JAXB would only expose properties that have bother getters and
setters. That said, I still doubt it will work as interfaces. The
jaxws spec really doesn't allow for that at all. Just concrete data
objects.
