我在SampleServlet.java中执行以下操作

//Fill resultset from db
....
try {
   ArrayList Rows = new ArrayList();

   while (resultSet.next()){
       ArrayList row = new ArrayList();
       for (int i = 1; i <= 7 ; i++){
           row.add(resultSet.getString(i));
       }
       Rows.add(row);
   }

request.setAttribute("propertyList", Rows);
RequestDispatcher requestDispatcher = getServletContext().getRequestDispatcher("/DisplayProperties.jsp");
requestDispatcher.forward(request,response);

然后在我的jsp DisplayPropeties.jsp中

<% 
     ArrayList rows = new ArrayList();

     if (request.getSession().getAttribute("propertyList") != null) {
         rows = (ArrayList ) request.getSession().getAttribute("propertyList");
     }
%>

但rows总是空的.

我究竟做错了什么？
