源码：
<!--ch3-4-include1.jsp-->
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
?<head>
???<title>被include包含的文件</title>
?</head>
?<body>
<h1>Hello World!</h1>
?</body>
</html>
<!--ch3-4-include2.jsp-->
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
?<head>
???<base href="<%=basePath%>">

???<title>include指令实例</title>
?</head>
?<body>
<center>
现在的日期和时间是：<%=new Date() %>
<hr>
<%@ include file="ch3-4-include1.jsp" %>
</center>
?</body>
</html>
这个错误是在我的这个代码里面是ch3-4-include1.jsp文件里多了 import="java.util.*"
然后把这个import="java.util.*"删除就不报错误了。再把其他多余的代码删掉

类似这些的删掉!!
