JAVA+FlexPaper+OpenOffice+SWFTools文档预览

http://blog.csdn.net/core_star/article/details/10148047

 

 

1、软件环境：

  • openoffice:启动openoffice服务：soffice.exe -headless -nologo -norestore -accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager
  • swftools
2、所需组件：
  • 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

3、程序源码：

  • java转换器的程序代码：
