Java+FlexPaper+swfTools仿文库文档在线阅读

原文出处：http://my.oschina.net/stephenzou/blog/144489?p=2

一、文档在线阅读思路 

    1.用OpenOffice把PPT、Word、Excel、Text转换为pdf
    2.用SWFTool将生成的pdf转换成swf，然后利用FlexPlayer实现在线预览播放
二、准备工作
    1.安装OpenOffice，官网下载地址：http://www.openoffice.org/download/index.html，最新版为3.4.1，我使用的版本为3.3.0：http://pan.baidu.com/share/link?shareid=1181746637&uk=1913152192#dir/path=%2F%E8%BD%AF%E4%BB%B6%E5%B7%A5%E5%85%B7
    2.启动OpenOffice服务，CMD命令进入OpenOffice安装目录下的program目录，键入如下命令
        soffice "-accept=socket,host=localhost,port=8100;urp;StarOffice.ServiceManager" -nologo -headless -nofirststartwizard
    
    参考资料：http://blog.csdn.net/hbcui1984/article/details/5109169
    3.下载JODConverter：http://sourceforge.net/projects/jodconverter/files/，项目中主要使用lib目录下的jar包。
    4.下载并安装SWFTools：http://www.swftools.org/download.html，下载exe文件安装完成即可
    5.下载FlexPlayer
    http://pan.baidu.com/share/link?shareid=1181746637&uk=1913152192#dir/path=%2F%E8%BD%AF%E4%BB%B6%E5%B7%A5%E5%85%B7
    官网下载地址：http://flexpaper.devaldi.com/download/，版本为2.1.5，与1.5.1有较大差别，未使用最新版。

三、软件开发 
    1.新建web项目并引入jar包
        阅读JODConverter/lib目录下的DEPENDENCIES.txt可知需要添加哪些jar包
        

        新建OfficeOnline项目，引入相应jar包（使用的是cos进行文档上传,cos.jar需要另外下载），将FlexPaper_1.5.1_flash.zip解压后的js目录引入到项目中，FlexPaperViewer.swf也引入进来
        
    2.新建DocConverter.java
        注意：根据SWFTools安装路径不同需要修改pdf2swf()方法中pdf2swf.exe的路径，我安装的路径是在D盘
                main()测试中根据自己文档路径进行修改测试。
