            String result = "";
            String url1 = "http://localhost:8080/getDVDList";
             URL url = new URL(url1);
          
            URL obj = url;
            HttpURLConnection con = (HttpURLConnection) obj.openConnection();

            // optional default is GET
            con.setRequestMethod("GET");

            //add request header
            con.setRequestProperty("User-Agent", "Mozilla/5.0");

            int responseCode = con.getResponseCode();
            System.out.println("\nSending 'GET' request to URL : " + url);
            System.out.println("Response Code : " + responseCode);

            BufferedReader in = new BufferedReader(
                    new InputStreamReader(con.getInputStream()));
            String inputLine;
            StringBuffer response = new StringBuffer();

                response.append(inputLine);
            }
            in.close();

            //print result
            result = response.toString();
            // Parse to get translated text


            JSONObject jsonObject = new JSONObject(result);

 2.)

                JSONObject jsonObject = new JSONObject(result);
                int code = jsonObject.getJSONObject("responseCode").getInt("code");

                if (code == 201) {
                    errorLabel.setForeground(Color.BLACK);

                } else {
                    errorLabel.setForeground(Color.RED);
                    errorLabel.setText("Adding DVD failed");
                }


3.)      String url1 = "http://localhost:8080/addDVD?title=" + URLEncoder.encode(title, "UTF-8").replace("+", "%20") + "&year=" + year + "&actors=" + URLEncoder.encode(actors, "UTF-8").replace("+", "%20") + "&ratings=" + ratings + "&definitions=" + definitions;
 
   con.setRequestProperty("Content-Type",
                        "application/x-www-form-urlencoded");
                con.setRequestProperty("Content-Language", "en-US");
                // optional default is GET
                con.setRequestMethod("POST");


 

 URLDecoder.decode (title);
