Not sure if this is going to be the right place to post about this, so
please forgive me. I don't know who owns the Jettison project....
I am using CXF. My problem is this. The object as follows throws an
exception ( listed at the end of this email) when I try to access it
through JSON. The XML access works fine and I get the correct XML. Note
that the annotations have no effect on the issue. The problem seems to
stem from the fact that the code is trying to turn a JSONArray into a
JSONObject. But I cant determine why that might be the case.
Any help would be greatly appreciated.
Thanks,
~Derek Shaw
The object rest method is:
@Get
@HttpResource(location = "/player/{ID}")
@WebResult(name = "Player")
public Player getPlayer(@WebParam(name = "ID") int ID)
throws PlayerNotFoundFault, PlayerFault;
The Player object is: (note that if I remove the List<T> objects the
problem goes away. )
