I need below kind of structure constructed in java and send it as response :

var abc = {"action":"Remove",

       "datatable":[

          {"userid":"userid0","username":"name0"},

          {"userid":"userid1","username":"name1"},

          {"userid":"userid2","username":"name2"},

          {"userid":"userid3","username":"name3"}

                ]

    ,

       "msgType":"success"};

I am doing:

JSONArray jsonArray = new JSONArray();



for (loop) {

    JSONObject jsonObj= new JSONObject();

    jsonObj.put("srcOfPhoto", srcOfPhoto);

    jsonObj.put("username", "name"+count);

    jsonObj.put("userid", "userid"+count);



    jsonArray .add(jsonObj.toJSONString());

}



Map paramMap = new HashMap();



paramMap.put("action", "remove");



paramMap.put("datatable", jsonArray );



paramMap.put(Constant.MSG_TYPE , Constant.SUCCESS);



getJSONMessage(paramMap);

and herer above function is converting paramMap into json string like:

public static String getJSONMessage(Map<String, String> paramMap){

    if(paramMap != null && paramMap.size() > 0)

        return JSONObject.toJSONString(paramMap);

    else

        return "";

}

but it is not creating the right structure, can anybody help me in this?

here is what I am getting output:

{"action":"Remove","datatable":["{"userid":"userid0","srcOfPhoto":"users/JMMBGTCHG.jpg","username":"name0"}"],"msgType":"success"}

which is not being parsed in javascript.

var json = eval('(' + respText+')');

alert("contents>>"+json.datatable);

alert("contents.datatable[0]>>>"+json.datatable[0].username);

last alert showing undefined.

ohh sorry I forgot to paste last line , here is the last line:

getJSONMessage(paramMap);

and above function is converting paramMap into json string:

public static String getJSONMessage(Map<String, String> paramMap){

    if(paramMap != null && paramMap.size() > 0)

        return JSONObject.toJSONString(paramMap);

    else

        return "";

}

JSONArray jsonArray = new JSONArray();



for (loop) {

    JSONObject jsonObj= new JSONObject();

    jsonObj.put("srcOfPhoto", srcOfPhoto);

    jsonObj.put("username", "name"+count);

    jsonObj.put("userid", "userid"+count);



    jsonArray.put(jsonObj.valueToString());

}



JSONObject parameters = new JSONObject();



parameters.put("action", "remove");



parameters.put("datatable", jsonArray );



parameters.put(Constant.MSG_TYPE , Constant.SUCCESS);

Why were you using an Hashmap if what you wanted was to put it into a JSONObject?

EDIT: As per http://www.json.org/javadoc/org/json/JSONArray.html

EDIT2: On the JSONObject method used, I'm following the code available at: https://github.com/stleary/JSON-java/blob/master/JSONObject.java#L2327 , that method is not deprecated.

We're storing a string representation of the JSONObject, not the JSONObject itself

JSONArray successObject=new JSONArray();

JSONObject dataObject=new JSONObject();

successObject.put(dataObject.toString());

This works for me.
