编写了一个简单的jstl的例子,怎么总是报错说是java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagLibraryValidator.到底怎么解决啊。我用的是myeclipse.

下面是我的源代码:

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

<%@ page language="java" import="java.util.*" pageEncoding="gbk"%>

<%

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>

<meta http-equiv="pragma" content="no-cache">

<meta http-equiv="cache-control" content="no-cache">

<meta http-equiv="expires" content="0">

<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">

<meta http-equiv="description" content="This is my page">

<!--

<link rel="stylesheet" type="text/css" href="styles.css">

-->

</head>

<body>

<c:out value="Hello, World"/>

</body>

</html>

>java.lang.NoClassDefFoundError: javax/servlet/jsp/tagext/TagLibraryValidator.

说明这个类没有,在google中键入这个类全名,得到jar包,下载到你的classpath中就可以,这好像是servlet的一个基本包中的。
