在JAVAWEB中下面的代码对不

源代码是</td>
      <td width="80">
      <a href="<%=request.getContextPath() %>/Xuank?yhm=${user.yhm }&&kec=${u.name }">选课</a>
     </td>

<servlet>是

public void doPost(HttpServletRequest request, HttpServletResponse response)
   throws ServletException, IOException {
  HttpSession session=request.getSession();
          request.setCharacterEncoding("gb18030");
           String yhm=request.getParameter("yhm");
           String kec=request.getParameter("kec");
           XhxxDao xhxx=XhxxFactory.getXhxxDao();
                         int f=xhxx.addx(yhm, kec);
                     if(f!=0){
                   if(f!=9000&&f!=9001){
                    session.setAttribute("loginer", "恭喜你！选课成功");
                   request.getRequestDispatcher("student/xkall.jsp").forward(request,response);
                   }else{
                    if(f==9000){
                     session.setAttribute("loginer", "对不起!您已选过课, 如果想重新选课, 请先退课！！！！！！");
                    request.getRequestDispatcher("student/xkall.jsp").forward(request,response);
                    }
                    if(f==9001){
                     session.setAttribute("loginer", "对不起!您所选的课超过限选数, 请选择其它课程.！！！！！");

                     request.getRequestDispatcher("student/xkall.jsp").forward(request,response);
                    }
                   }
                  }else{
                   request.setAttribute("loginer","很愦憾!选课失败！！！！！");
                   request.getRequestDispatcher("student/xkall.jsp").forward(request,response);
