出现此问题的原因：在jsp页面用到了struts提供的ajax主题，但是声明主题时出现问题，struts2.0到struts2.1有一个重
要的改变就是对ajax支持的改变，struts2.0的ajax支持主要以DWR和dojo为主，并专门提供ajax主题,如：<s:head
theme="ajax"/>,但是在struts2.1不在提供ajax主题，而将原来的ajax主题放入了dojo插件中，我们需要将dojo
标签引入到jsp页面，一般为:<%@ taglib prefix="sx"
uri="xxxxxxx"/>，并将前面的ajax主题声明改成<sx:head/>,ok,重新启动服务，问题解决。
struts2.1 Tabbedpanel标签实现选项卡效果

转载
标签：struts2.1tabbedpanelajax标签实现选项卡效果it | 分类： SSH框架 |
按照下面操作进行
1.现在使用的时候首先要导入一个库 :
struts2-dojo-plugin-2.1.6.jar
2.在要生成日期控件的页面头部加上：
<%@ taglib prefix="s"
uri="/struts-tags"%>
<%@ taglib prefix="sx"
uri="/struts-dojo-tags" %>
3.然后在web页面的
head标签下面加上<sx:head/>
也可以加上下面两句话
<s:head theme=
"xhtml"
/>
<sd:head parseContent="true"
/>
4.实现各种选项卡效果的示例：
<%@ page language="java" contentType="text/html;
charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ taglib uri="/struts-tags"
prefix="s"%>
<%@ taglib uri="/struts-dojo-tags"
prefix="sx"%>
