Can't pass data using JsonpRequestBuilder

Greetings,

I have a GWT app talking to a Java servlet just fine except I can't seem to pass data.  I've already spent a day on it.  Any help would be greatly appreciated.

I am using JsonpRequestBuilder and attempting to get around SOP.  Here is my server code:

public class GWTServlet extends HttpServlet {

protected void processRequest(HttpServletRequest request, HttpServletResponse response)

throws ServletException, IOException {

String callback = request.getParameter("callback");

PrintWriter out = response.getWriter();

try {

out.print(callback + "([{\"Hello\": \"world\"}]);");

} finally {

out.close();

}

}....

Here is my GWT code:

public void onClick(ClickEvent event) {

JsonpRequestBuilder jsonprb= new JsonpRequestBuilder();

jsonprb.requestObject("http://localhost:8084/XXX/GWTServlet", 

new AsyncCallback() {

              @Override

              public void onFailure(Throwable caught) {

                  Window.alert("Failure getting JSONP directly from remote server");

              }

@Override

public void onSuccess(Object result) {

Window.alert("Got response");

JavaScriptObject res = (JavaScriptObject) result;

Window.alert(res.toSource());

}

          });

I get the "Got response" message.  I am also able to put break points on the frontend or backend and it gets to where I expect.  The problem is that I can't seem to get at the data send from the server.  I don't know what to do in onSuccess().

Of course, once I get this working I will have the same challenge going the other way.  Help is greatly appreciated.
