映射访问WEB-INF下的jsp文件问题

上面是web.xml配置文件，放在webapps/web1/WEB-INF下面，web1是我自建的文件，服务器tomcat7.0. 上面没有贴出jsp文件test1.jsp，它和web.xml放在一起。在当我在浏览器中地址栏输入地址：http://localhost:8080/web1/hello.adml
提示错误：

HTTP Status 500 -

这个该怎么改，才能通过映射访问WEB-INF下的文件？？？

------解决方案--------------------
servlet是后台的提交对象~ 你这里没有 
这么还定义个servlet呢！
------解决方案--------------------
哥们你太有才了，页面跳转到servlet里面去跳啊

这样怎么跳，你以为这是struts2啊
