    public void doGet(HttpServletRequest request, HttpServletResponse response)

        ServletContext context = this.getServletContext();
        Properties pro = new Properties();
        pro.load(context.getResourceAsStream("/WEB-INF/classes/db.properties"));
        String value = pro.getProperty("name");
        PrintWriter out = response.getWriter();
        out.println(value);
