 以下出错原因是没有找到对应的结果，这个是struts没有配置好，系统找到返回结果的页面，解决方案如下

<package name="login" namespace="/" extends="struts-default">
	<action name="login" class="com.login.action.LoginAction">
		<result name="error">/error.jsp</result>
		<result name="success">/success.jsp</result>
	</action>
</package>

 在package里面增加 namespace="/" 告诉系统是从根本录寻找
