Unless I am overlooking something, you simply need to associate the key
“data” with the Java list you want to be converted to a JSON list like
this:
result.put("data", *the java list you want to be converted in JSON*);
return result;
The <response name="success" type="request" value="json"/> is supposed
to convert the service result map (plus other things) to JSON
auto-magically.
