public class InitServlet extends HttpServlet { 
    private int interval = 10;
    public InitServlet() {
        super();
        interval = Integer.parseInt(getInitParameter("interval"));
    }
    public void destroy() {
        super.destroy();
        // Just puts "destroy" string in log
        // Put your code here
    }

 
    public void doGet(HttpServletRequest request, HttpServletResponse response)
           throws ServletException, IOException {
          doPost(request, response); 
    }
    public void doPost(HttpServletRequest request, HttpServletResponse response)
       throws ServletException, IOException {
    }
   public void init() throws ServletException {
       ServletContext application = getServletConfig().getServletContext();
       String realpath = this.getServletContext().getRealPath("/");
  
      new DaemonThread(this.interval).start();
 }
 
}
