Ok, you mean JSON*P*Request and JSON*P*Response, or?
JSON-P is a little different from normal JSON, it requires to be wrapped in
a callback function. Your response should look like this:
callback({"getRolesResponse":{"return":["Executive","Manager","SuperAdmin"]}}
);
The call to the callback function is required to make cross domain Ajax
work. GWT uses a function named 'callback' by default, but you can change
it.
You'll need to extend your server code to create the above result:
jsonpResponse = "callback(" + generatedJsonResponse + ");"
where "generatedJsonResponse" is the JSON generated by your JSON library.
You should only use JSON-P, if you want do do cross-domain Ajax. If
cross-domain is not required, use the RequestBuilder and JSONParser to do a
normal Ajax request and parse the resulting String.
