原创 http://hwl-sz.iteye.com/blog/1964397

1、开发前准备

1)下载第三方软件或插件进行安装

openOffice：官方下载：http://www.openoffice.org/download/

                      百度网盘：http://pan.baidu.com/s/1mpxdL

      swftools：官方下载：http://www.swftools.org/swftools-0.9.0.exe

                      百度网盘：http://pan.baidu.com/s/11O0nS

FlexPaper_1.4.5_flash：http://pan.baidu.com/s/1oXmIL

Linux版本的安装及下载见：《openOffice、swftools安装指南（Linux）.doc》

2)下载相关的jar包，如下图：
3)集成插件

解压FlexPaper_1.4.5_flash.zip，将以下文件移植到web目录下,如图
2、编写代码

项目源代码下载：[url]http://pan.baidu.com/s/18AcnQ [/url]
