 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:

    博客分类: JAVAWEBJAVASCRIPT 在线预览预览WORDXLSPPT


 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
