@Richard At the end of the day you might find that it saves you a lot of time using jbossxb instead of writing your own unmarshalling layer. This is time you can spend on your main project instead ;-) Alexey, is indeed very responsive when it comes to resolving technical issues. jbossas uses jbossxb for all its configuration tasks (which are non-trivial in places). Please also remember that we used jbossxb for the jax-rpc part in jbossws. We could never have delivered on time if we had to do our own XML marshalling layer. I agree that the entry to jbossxb is high because of it sucks in documentation. Which is probably the root of your jbossxb adoption problem. You can monitor https://jira.jboss.org/jira/browse/JBXB-208 for this issue. Anyway, good luck with your (main) project.
