Re: JSON and JAX-RS
Well, looking at the code, it seems to create a new JAXBContext for each top level type, which really sucks. IMO, it should use our JAXBDatabinding in some way which would allow it/you to configure things via spring or something so one one JAXBContext is created/used that would have all the required types in it. Actually, checking if there is an ObjectFactory in the package and creating the context based on that would also go a long way to helping. That said, with JAXB 2.1, you can probably add an @XmlSeeAlso annation on the wsResponse that points to the wsMessage to make the JAXBContext for the wsResponse be able to marshal the wsMessage as well.

Effectively I have an object called wsResponse that, in this case, is returning an array of messages (wsMessage) - I have decorated both objects with the XMLType. I am looking into this exception and see references to JAXB; is it possible to get around this?

RE: JSON and JAX-RS
Interesting. Would that mean I would have to use seekAlso and list all of the objects that could possibly be returned - I have currently about six types of custom objects. What if I was returning a type like a boolean or just a string?

IMO, it should use our JAXBDatabinding in some way which would allow it/you to configure things via spring or something so one one JAXBContext is created/used that would have all the required types in it. Actually, checking if there is an ObjectFactory in the package and creating the context based on that would also go a long way to helping. That said, with JAXB 2.1, you can probably add an @XmlSeeAlso annation on the wsResponse that points to the wsMessage to make the JAXBContext for the wsResponse be able to marshal the wsMessage as well.
