JAVA+FlexPaper+OpenOffice+SWFTools文档预览
1、软件环境：
2、所需组件：
- openoffice:启动openoffice服务：soffice.exe -headless -nologo -norestore -accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager
- swftools
3、程序源码：
- flexpaper ： flexpaper_flash_debug.js，flexpaper_flash.js,jquery.js ， FlexPaperViewer.swf
- OpenDocument文档转换器 JODConverter， 主要用它的jodconverter-2.2.2.jar包
- java转换器的程序代码：
