项目管理

2.我的jsp页面放在WEB-INF目录下
3.我的jsp页面，page1.jsp包含head.jsp,下面贴出代码：
page1.jsp

<jsp:include page="/WEB-INF/jsp/common/header_basic.jsp">
<jsp:param name="pageTitle" value="首页"/>
</jsp:include>
<body>
页面内容

<%@ page isELIgnored="false" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<meta http-equiv="description" content="This is my page">
</head>
我取到的页面标题总是
求帮助
好吧，我自己解决了，网上很多文章根本自己没验证过哈，误人子弟
在取数据的时候，应该从request对象当中取，el表达式呢${pageTitle}自然是取不到的，正确的写法应该是
${param.pageTitle}
