        //populate initialize resources
        message = "Hello world - my Basic Servlet";
    }

    @Override
    protected void service(HttpServletRequest request, HttpServletResponse response) throws IOException {
        System.out.println("=====service method is called ====");
        //render to html page
       // Set response content type
        response.setContentType("text/html");

        // Actual logic goes here.
        PrintWriter out = response.getWriter();
        out.println(String.format("<h1> %s </h1>", message));
    }

    @Override
    public void destroy() {
