请求热心人给指点
昨天晚上还好好的，今天用就悲剧了，服务器也重启过了，myeclipse也重启过了
难道我s:form标签真的用错了吗？？？

[解决办法]
<s:form action="stu_login" method="post" namespace="/stu">

namespace是干啥的？另外action 不加 / 吗？

[解决办法]
测试的时候把其他不相关的项目CLOSE了试试
还有你改过struts.properties文件了？
[解决办法]
default.properties 说错了
[解决办法]
强哥，对于你目前的各种代码，俺都没看出问题啊！！！或许不是程序的事，是配置的事呢？
[解决办法]
stu_login.jsp(30,2) The s:form tag declares that it accepts dynamic attributes but does not implement the required interface

翻译过来的大概意思就是你的S:form标签声明了冰且能够接收动态的属性但是没有实现一个必须得接口

namespace是命名空间这个你知道的

既然报的事JSP页面异常就在这漫漫找把 LZ好运
[解决办法]
<action name="index">
<result>/stu_login.jsp</result>
</action>
把class 跟 method属性写完
[解决办法]
org.apache.jasper.JasperException: /stu_login.jsp(30,2) The s:form tag declares that it accepts

struts 标签错误，仔细更改
[解决办法]
<s:form action="stu_login" method="post" namespace="/stu">
我一般不是这样写的，改为<s:form action="stu/stu_login.action" method="post">试试
