send post request with HttpClient and use servlet to display the request

Hello i am sending a post message using a HttpClient. But i dont see the request in my servlet. I am sure this method is fine, i used it before. I tried with another method too.
Java code:
Method 1:

Method 2:

public static void sendPostRequest() {

//Build parameter string
        String data = "message=123";

try {

// Send the request
            URL url = new URL("http://alexgifei.s156.eatj.com/servlets-examples/servlet/Request");
            URLConnection conn = url.openConnection();
            conn.setDoOutput(true);
            OutputStreamWriter writer = new OutputStreamWriter(conn.getOutputStream());

//write parameters
            writer.write(data);

writer.flush();

// Get the response
            StringBuffer answer = new StringBuffer();
            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            String line;
            while ((line = reader.readLine()) != null) {
                answer.append(line);
            }
            writer.close();
            reader.close();

//Output the response
            System.out.println(answer.toString());

} catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
