熟悉struts2.0的朋友，请帮忙看看小生的疑惑。谢谢

刚学struts2.0，在研究一个别人写的小项目。当我新建一个jsp时，不论用到struts2.0的任何标签都不能直接访问这个页面。除非在别的页面用个超链接，先转到Struts.xml配置文件中，在有action 转向那个页面。不知道为什么？ 
比如：我的jsp页面login.jsp 
<%@page contentType="text/html"%> 
<%@page pageEncoding="UTF-8"%> 
<%@ taglib prefix="s" uri="/struts-tags" %> 
<html> 
   <head>   
     <title>login </title> 
   </head>   
   <body>   
     <s:label> 
        <tr> 
         <td>test </td> 
        </tr>     
     </s:label>    
   </body> 
</html> 
输入：http://localhost:8080/portal/login.jsp 
这个页面只要能够用到2.0任何标签都不能直接访问，不用的话就可以访问。 如果用标签，想访问的话就要在Struts.xml中配置 <package name="user" extends="struts-default" namespace="/u"> 
<action name="login-jsp"> 
<result>/news/admin/login.jsp </result> 
</action> 
</package> 输入:http://localhost:8080/portal/u/login-p.jsp才能访问我的login.jsp 
我不知道是什么原因，明白的人请给我指点一下。谢谢呀
