标题:
Struts标签set范围问题
struts2.1关于set标签范围测试的，怎么结果都一样啊？？？？[code=jscript]<%@ page language="java" pageEncoding="GB18030"%>
<%@ taglib uri="/struts-tags" prefix="s" %>
<html>
<head>
<title>tags.jsp</title>
</head>
<body>
<h1>tags</h1>
property 取得Action属性的值,值栈中存在:<s:property value="name"/>
property 只是一个字符串:<s:property value="'zifuchuan'"/>
<hr/>
<!--以下是出问题的代码： -->

<s:set var="admin" value="name"/>

你试试[code]<s:set name="admin" value="name"/>[/code]把那个var改成name set好像必须要name属性。[code][/code]
