这个是我按书上写的web.xml
<?xml version="1.0" encoding="GB2312"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
version="2.4">
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/core</taglib-uri>
<taglib-location>/WEB-INF/tld/c.tld</taglib-location>
</taglib>
<taglib>
<taglib-uri>http://java.sun.com/jsp/jstl/fmt</taglib-uri>

<taglib-uri>http://java.sun.com/jsp/jstl/functions</taglib-uri>
<taglib-location>/WEB-INF/tld/fn.tld</taglib-location>
</taglib>
</web-app>
这个是例子
<%@page contentType="text/html" pageEncoding="GB2312"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<!DOCTYPE html>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GB2312">
<title>测试JSTL是否工作</title>
</head>
<body>
<c:out value="恭喜你，JSTL已经成功安装 ！"/>
</body>
</html>
这是我把鼠标放在<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>这句话时出现的提示
The absolute uri: http://java.sun.com/jsp/jstl/core cannot be resolved in either web.xml or the jar files deployed with this application
并且我在NetBeans中已经引入了standard.jar和jstl.jar两个jar包，但是还是运行不成功
有哪位高手指导一下啊？谢谢

netbeans中就是xml文件比较多，看的头疼，还是用Myeclipse比较好！
