Return JsonObject in spring restful webservice

Question

I am using spring framework. I have a webservice in Wepsphere server like that

@RequestMapping (value="/services/SayHello2Me" , method=RequestMethod.GET, headers="Accept=application/json")
@ResponseBody
public JSONObject SayHello2Me(HttpServletRequest request) throws Exception {
    String input = (String) request.getParameter("name");
    String output = "hello " + input + " :)";
    JSONObject outputJsonObj = new JSONObject();
    outputJsonObj.put("output", output);
        return outputJsonObj;
      }

When I call it form Chrome like http://myserver/services/sayHello2Me?name='baris', it returns me that error :

Error 404: SRVE0295E: Error reported: 404

If I change annotions in my webservice like that

@RequestMapping (value="/services/SayHello2Me")
@ResponseBody
public JSONObject SayHello2Me(HttpServletRequest request) throws Exception {

    String input = (String) request.getParameter("name");
    String output = "hello " + input + " :)";
    JSONObject outputJsonObj = new JSONObject();
    outputJsonObj.put("output", output);

    return outputJsonObj;
  } 

then when I call it form Chrome like http://myserver/services/sayHello2Me?name='baris', it returns me that error :

Error 406: SRVE0295E: Error reported: 406

There is a jsonobject problem because if I return String insted of jsonobject in same webservice it returns me successfully.

How can I return Jsonobject in spring restful webservice?

406-Not Acceptable Response

you should use return outputJsonObj.toString(); try below as

@RequestMapping (value="/services/SayHello2Me")
@ResponseBody
public String SayHello2Me(HttpServletRequest request) throws Exception {

String input = (String) request.getParameter("name");
String output = "hello " + input + " :)";
JSONObject outputJsonObj = new JSONObject();
outputJsonObj.put("output", output);

return outputJsonObj.toString();
}

You can use jackson:

@RequestMapping (value="/services/SayHello2Me" , method=RequestMethod.GET, produces="application/json")
