你的方法定义写错了：
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response,HttpSession session) throws ServletException, IOException {
应该是：
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
session从response中取得
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response,HttpSession session) throws ServletException, IOException {
应该是：
//Process the HTTP Get request
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
session从response中取得

把HttpSession session写在下面
HttpSession session = request.getSession() ;
HttpSession session = request.getSession() ;
