Java web：转发方式跳转，页面上显示，友情链接的页面【诗书画唱】
3、创建一个query.jsp页面,创建Product商品类（包含名称，价格和进货日期），在这个页面中创建一个List<Product>集合，通过转发方式跳转到result.jsp页面，在result.jsp页面中（注意不是后台打印，是页面上显示）显示商品的所有信息。
<%@page import="com.SSHC.Product"%>
<%@page import="java.util.ArrayList"%>
<%@page import="java.util.List"%>
<%@ page language="java" contentType="text/html;
charset=UTF-8"
pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"
+request.getServerName()+":"+request.getServerPort()
+path+"/";
List<Product> list = new ArrayList<Product>();
request.getRequestDispatcher("result.jsp")
.forward(request, response);
%>

4、设计一个友情链接的页面，这个页面有一个列表，能够跳转到指定的网站去。
淘宝网
京东网
猫扑网
百度网
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
下面是用超链接的方法跳转到指定的网站：<br/>
<h1>友情链接:</h1>
<a href="http://www.taobao.com">淘宝网</a>
<a href='http://www.jd.com'>京东网</a>
<a href='http://www.mop.com'>猫扑网</a>
<a href='http://www.baidu.com'>百度网</a>
</body>
</html>
