这是我的prog1:

public class DispatcherSample extends HttpServlet
{
    public void service(HttpServletRequest request,HttpServletResponse response)throws IOException,ServletException
    {
        PrintWriter out=response.getWriter();
        out.println("we are in first servlet.");
        request.setAttribute("name","sanjay");
        RequestDispatcher rd=request.getRequestDispatcher("/ss");
        rd.forward(request,response);
        }
}

这是我的prog2:

public class SecondServlet extends HttpServlet
{
    public void service(HttpServletRequest request,HttpServletResponse response)throws IOException,ServletException
    {
        PrintWriter out=response.getWriter();
        out.println("we are in second servlet.");
        request.setAttribute("surname","korlepara");
        //RequestDispatcher rd=request.getRequestDispatcher("/ts");
        //rd.forward(request,response);
        out.println(request.getAttribute("name"));
        out.println(request.getAttribute("surname"));
    }
}   

OUTPUT是:我们在第二个servlet中.null korlepara

问题是:无法检索属性名称
