There is nothing that i know of "out of the box" to help you do this
with JAXB, or for that matter any other XML-based Java API.
The NetBeans RESTful Web services plugin generates JAXB beans that
nicely handles links (that are mapped to ID fields of entity beans). You
could look at that generated code for tips/tricks.
I think this is an area we need to look more closely at as the
"connectedness" property is probably the one area where there is least
support, but i suspect is rather hard to get right with a good balance
of flexibility without being too imposing (and i suspect tooling could
play a really helpful modeling role). Currently we only have easy ways
to safely build URIs.
There might be a way to consider the JAXB tree a model and to have a
template engine approach, but we need to make some serious refactoring
work in the 0.6 version before we can experiment with that approach.
Paul.
