在线文库解决方案Jacob+SwfTools+FlexPaper

课程作业,准备做一个类似于豆丁之类的在线文库,解决方案也就是将文档(doc ppt xls)等转换成pdf,然后转成swf展示在页面中,今天下午经过研究,参考其他人的博客,实现了这个主要功能,这里也做下记录。

@肖恩也有梦想 http://www.cnblogs.com/luckyxiaoxuan/archive/2012/06/13/2548331.html 思路已经介绍的很详细了,下面我给出一个示例代码,来自http://blog.csdn.net/catoop/article/details/43150671 ,具体的可以去@肖恩也有梦想 查看。

我用线程池加了个多线程的支持,代码http://files.cnblogs.com/files/ywind/Convert.zip
