Question

I’m using GWT as web development framework. I need to access some REST services from my GWT client code. Also I need to parse JSON (or maybe XML) which is response format of these services. Which is the best way for this problem?

Thanks in advance.

Answer 1

You can call REST services using the standard GWT RequestBuilder (or JsonpRequestBuilder if you need to call services on another domain).

With the JSON response string, you can call JSONParser.parseStrict(jsonString) to get a JSONValue, which can be a JSONObject, JSONArray, etc. This is all available in this package.
