实现在线阅读的方法，如百度文库一样。

1.准备工作：下载OpenOfice及PDF转换工具pdf2swf.exe

OpenOfice下载地址:http://www.openoffice.org/download/index.html

Pdf2swf工具下载:http://www.openoffice.org/download/index.html

2.安装上面两个工具以及启动OpenOfice服务：

   a 安装简略
   b OpenOfice启动：

        进入OpenOffice的安装目录找到program目录，输入以下命令:

        soffice -headless -accept="socket,host=127.0.0.1,port=8100;urp;" -nofirststartwizard &

3.建工程如图结构：

  

重要的两段代码
