osworkflow 入门基础2

[quote]前篇我引入了互联网上找来的一篇文章，接着上篇讲：osworkflow 工作流是非常轻量级的，虽然2006就停止活动了，互联网上的资料也不是很多，官网也没过多的说明，比起jbpm 和activiti来说资料是相当少，但是不妨碍我们学习这个轻量级的工作流引擎。闲话少说[/quote]

[quote]demo1 入门
需要导入依赖：
lib/commons-logging.jar
oscore-2.2.5.jar
osworkflow-2.8.0.jar
propertyset-1.4.jar

要执行的业务函数：这里我用simulate 模拟打开一个浏览器的操作
