Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    String data = URLEncoder.encode("key1", "UTF-8") + "=" + URLEncoder.encode("value1", "UTF-8");

    Socket socket = new Socket("127.0.0.1", 8080);

    String path = "/servlet";
    BufferedWriter wr = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream(), "UTF8"));
    wr.write("POST " + path + " HTTP/1.0\r\n");
    wr.write("Content-Length: " + data.length() + "\r\n");
    wr.write("Content-Type: application/x-www-form-urlencoded\r\n");
    wr.write("\r\n");

    wr.write(data);//from   w ww . j  a  v a 2  s  .com
    wr.flush();

    BufferedReader rd = new BufferedReader(new InputStreamReader(socket.getInputStream()));
    String line;
    while ((line = rd.readLine()) != null) {
        System.out.println(line);
    }
