相信现在关注工作流的人越来越多了，我也是其中之一，上网狂搜了一下，发现很多人说开源的工作流OSWorkFlow还不错，我也Download下载研究研究。

文档很少，只有上网再搜，发现很多资料都是你转载我，我转载你，原创的不多。反来复去地看了看网上的资料，再看看OSWorkFlow的自带文档，调试带的例子。

发现那个例子说明性不是很强，把人弄得很晕，经过一翻分析，我把例子修改了一下，添加了些注释，一些JSP页面也修改了一下并进行了汉化，设定了几个用户组，分别具有不同的权限，使工作流流转起来真正象个工作流。希望能对刚开始学习工作流的同志有所帮助。下面我贴出工作流定义的XML文件。完整的例子请到我的网络硬盘下载。下载地址：http://wallimn.gbaopan.com
