照着《利用JBuilder 2005 开发Spring实例》这篇文章做到第一步显示，但总是报错，不知道是什么原因，请高手指教!
以下是我做的几个文件：
hello.jsp
<%@ page contentType="text/html; charset=GBK" %>
<html>
<head><title>Example :: Spring Application</title></head>
<body>
<h1>Hello - Spring Application</h1>
<p>Greetings.</p>

＜servlet-mapping＞
＜servlet-name＞springapp＜/servlet-name＞
＜url-pattern＞*.htm＜/url-pattern＞
＜/servlet-mapping＞
改成
＜servlet-mapping＞
＜servlet-name＞springapp＜/servlet-name＞
＜url-pattern＞*.jsp＜/url-pattern＞
＜/servlet-mapping＞
不要改成*.jsp，<prop key="/hello.jsp">springapp</prop>这个地方也要改
因为你的页面也叫hello.jsp，url-pattern也叫hello.jsp，
return new ModelAndView("hello.jsp");这样调用会使你的容器进入死循环
