1.应用表格对页面进行布局（可以借助于Dreamweaver 制作页面框架)，如下图所示。表格中显示的文件内容为使用include指令引入相应的JSP文件（JSP文件的内容不限)。

任务四
编写一个JSP文件，在该文件中，应用Math.round(Math.random()*10)生成[0,10]之间的随机整数，然后根据生成的是偶数还是奇数，应用<jsp:forward>动作标记分别跳转到对应的偶数页面和奇数页面。
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%> <% 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 'test06.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> <% double r=(int)(Math.random()*10)+1; if(r%2==0){ %> <jsp:forward page="t1.jsp"> <jsp:param value="<%=r %>" name="num"/> </jsp:forward> <% } else{%> <jsp:forward page="t2.jsp"> <jsp:param value="<%=r %>" name="num"/> </jsp:forward> <% } %> </body> </html>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> <% 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> </head> <body> <%String r=request.getParameter("num"); out.print("Hello,我是一个奇数"+r); %> </body> </html>
