Taking Response Back from Servlet.


  public static void main(String[] args) throws MalformedURLException, IOException {
       URL oracle = new URL("http://localhost:8080/ServletDemo/LoginServlet");
        URLConnection yc = oracle.openConnection();
        BufferedReader in = new BufferedReader(new InputStreamReader(
                                    yc.getInputStream()));
        String inputLine;
        while ((inputLine = in.readLine()) != null)
            System.out.println(inputLine);
        in.close();
    }
}

Web_Service

create Servlet and paste code in body tag ;

response.setContentType("text/html;charset=UTF-8");
        String user = request.getParameter("name");
        String pass = request.getParameter("password");
      
        System.out.println(user);
        System.out.println(pass);
        OutputStream os = response.getOutputStream();
        String str = "success";
        os.write(str.getBytes());
