Beside this I think JSON should be used for lightweight data structures.
Then it should be ok to work directly in the low-level space.
In your case I suggest to convey directly the original array.
Then you can think about something like:
@HttpMethod("GET")
@ProduceMime("application/json")
public JSONArray getMessage() throws JSONException {
return new JSONArray(states);
}

The Bookmark sample uses directly JSON providers, no JAXB involved.
I will publish a blog entry today with a sample showing generation of JSON
out of JAXB object.
