@H_404_2@有时候会出现Method public java.util.List org.apache.-------------------省略

@H_404_2@原因：想要客户端校验起作用，必须先进入Struts2核心Filter，直接进入JSP是不行的。

@H_404_2@所以在struts2上加上：

<actionname="*">
<result>/WEB-INF/content/{1}.jsp</result>
</action>

@H_404_2@在外部写个主页什么的：类似下面这个JSP

	<s:formaction="Register">
		<s:submitvalue="注册"/>		
	</s:form>
	<s:formaction="Login">
		<s:submitvalue="登录"/>
	</s:form>

@H_404_2@这样就从主页跳转到JSP 就可以响应前台校验了。
