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./download/ 百度网盘：http://pan.baidu.com/s/1mpxdL
swftools：官方下载：http://www./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：
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：http://pan.baidu.com/s/18AcnQ
