今天在做一个SSH整合测验时发现了一个异常（According to TLD or attribute directive in tag file）
严重: Servlet.service() for servlet jsp threw exception
org.apache.jasper.JasperException: /WEB-INF/page/employee.jsp(24,3) According to TLD or attribute directive in tag file, attribute items does not accept any expressions
org.apache.jasper.JasperException: /WEB-INF/page/employee.jsp(24,3) According to TLD or attribute directive in tag file, attribute items does not accept any expressions
页面上的源码如下：
1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
2 <%@ taglib uri="/struts-tags" prefix="s" %>
3 <%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
4 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
5 <html>
6 <head>
7
8 <title>employee</title>
9
10 <meta http-equiv="pragma" content="no-cache">
11 <meta http-equiv="cache-control" content="no-cache">
12 <meta http-equiv="expires" content="0">
13
14 </head>
15
16 <body>
17 ONGL:
18 <s:iterator value="#request.employees">
19 <s:property value="username"/>,<s:property value="password"/>,<s:property value="gender"/>
20 </s:iterator>
21 <br/>
22
23 JSTL/EL:
24 <c:forEach items="${employees}" var="employee">
25 ${employee.username}, ${employee.password}, ${employee.gender}<br/>
26 </c:forEach>
27 </body>
28 </html>
异常提示，在第24行的时候发生错误，说不接受任何表达式，后来在网上找到一个解决方案，说是版本不支持EL，所以把
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
改为：
<%@ taglib uri="http://java.sun.com/jstl/core_rt" prefix="c"%>
一定要记得加引号!
就输出正常了。
