java JSON response

Question

I'm trying to read the json response of a request post. This is the code ...

        connection.getOutputStream().write(paramDataBytes);
        Reader in = new BufferedReader(new InputStreamReader (connection.getInputStream(),"UTF-8"));
        StringBuilder sb = new StringBuilder();
        for(int c;(c=in.read())>=0;)
            sb.append((char)c);
        String response = sb.toString();
        System.out.println(response);
        JSONObject myResponse = new JSONObject(response.toString());

but the of response variable is

"?; ?m???×"}?iU?(s? ?0?p?6]p????E??*?Q????*U@?g?-x??1D@ ?H??P?{?a?P??w?KV?"

why?

when I try to create the object "JSONObject myResponse " I have the following error

Exception in thread "main" org.json.JSONException: A JSONObject text must begin with '{' at 1 [character 2 line 1]
    at org.json.JSONTokener.syntaxError(JSONTokener.java:505)
    at org.json.JSONObject.<init>(JSONObject.java:215)
    at org.json.JSONObject.<init>(JSONObject.java:399)
    at com.application.HttpRequestRaffle.main.Main2.main(Main2.java:83)

I desperately need help...

this is the response of the request that I do manually through firefox

Are you sure the called URL returns valid json output? Maybe the error is not on your side.. I have also found this example of calling an URL to get json response, it uses json parser, but if you will get an text as you mentioned, then it will not be working for sure — xxxvodnikxxx

Hi, thanks for followup and feedback, if possible please put it as a answer and once it will be possible accept it by your own. That will help for proper post filtering, etc.. — xxxvodnikxxx
