The best solution will be probably testing if the class can be handled. I'm not sure if there is a way to check it using JAXB APIs.

We had to go through considerable gymnastics to get down to a usable set of classes in the JAX-WS support for Axis2.  Here's a pointer to part of what we had to do to determine whether a class was usable:

http://svn.apache.org/viewvc/webservices/axis2/trunk/java/modules/jaxws/src/org/apache/axis2/jaxws/message/databinding/JAXBContextFromClasses.java?view=markup

Specifically, the separate() and findBestSet() methods are the key.  The net is, if the class can be added to a JAXBContext, then the assumption is that the class is usable for marshalling/unmarshalling.

This is an alternative to an exhaustive approach of checking the class' hierarchy looking for JAXB annotations.

So...  maybe that means we can assume that if the class is part of the JAXBContext that we have, then the isWritable should pass?  Maybe, but something makes me uncomfortable with that approach.
