初识JPBM

早在去年就买了一本工作流方面的书，因为各方面的原因，一直没有时间来学习，现在公司正好又用到了，所以算是故书新读，我们下面就先来认识一下JBPM,现在最新的版本是JPBM5来看一下官方对它的介绍：

It is based on the BPMN 2.0 specification and supports the entire life cycle of the business process (from authoring through execution to monitoring and management).

The current jBPM5 snapshot offers open-source business process execution and management, including

• embeddable, lightweight Java process engine, supporting native BPMN 2.0 execution
• BPMN 2.0 process modeling in Eclipse (developers) and the web (business users)
• process collaboration, monitoring and management through the Guvnor repository and the web console
• human interaction using an independent WS-HT task service
• tight, powerful integration with business rules and event processing

jBPM（JBoss Business Process Management业务流程管理），它是覆盖了业务流程管理、工作流、服务协作等领域的一个开源的、灵活的、易扩展的可执行流程语言框架。 
　jPDL是构建于jBPM框架上的流程语言之一。在jPDL中提供了任务（tasks）、待处理状态 （wait states）、计时器（timers）、自动处理（automated actions）…等术语，并通过图型化的流程定义，很直观地描述业务流程。
　jPDL可以部署于Java语言的任何应用环境下，JavaSE Application(Swing/SWT)、JavaEE Application(Application Server)  。是一个轻量级的组件，
