第一步：

jsp：1

复制代码代码如下:

<%@page import="java.util.Random,java.util.GregorianCalendar"%>

<?xml version="1.0" encoding="utf-8"?>

<items>

GregorianCalendar calendar = new GregorianCalendar();

int year = calendar.get(calendar.YEAR);

int month = calendar.get(calendar.MONTH) + 1;

int today = calendar.get(calendar.DAY_OF_MONTH);

String strday=year+","+month+","+today+",";

int sb = 400;

String[] dates = new String[] {strday+"14,60"};

String crutime=request.getParameter("time");

///crutime=crutime.replace(":",",");

if(crutime!=null){

crutime=crutime.replace(":",",");

dates = new String[] {strday+crutime};

}

for (int i = 0; i < dates.length; i++) {

Random random = new Random();

int r = random.nextInt(1000);

if (i < 10) {

%><%=r%>

}

</value> <date><%=dates[i]%></date> <sb><%=sb%></sb> </item>

}

</items>

jsp：2

复制代码代码如下:

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>

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

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

<head>

</head>

var so = new SWFObject("<%=path%>/testfrist.swf", "Main", "600", "400","9.0", "#ffffff", "high");

so.addVariable("myAmfurl","<%=path%>/nxsy.jsp");

so.addVariable("myAmtitle","牛熊双赢");

so.write("flashcontent");
