Parsing Map to JSON using JSON Simple

Question

I am using Gson library to convert Map to JSON. But requirement is to use json-simple-1.1.1. I google for solution but my bad luck couldn't get solution.

I want to use JSON Simple to achieve following operation:

/** Converting Map to JSON and sending response back to view */
private void write(HttpServletResponse response, Map<String, Object> map) throws IOException {
    response.setContentType("application/json");
    response.setCharacterEncoding("UTF-8");
    response.getWriter().write(new Gson().toJson(map)); 
}

any help is appreciated!

Try to use

//import org.json.simple.JSONValue;

String jsonText = JSONValue.toJSONString(map);
System.out.print(jsonText);

Try it, this will work:

org.json.simple.JSONObject jsonObj = new org.json.simple.JSONObject();
String jsonStr = jsonObj.toJSONString(map);
