基于JMS的Simflow工作流管理系统

本文介绍了一种基于JMS进行消息传递的分布式工作流管理系统Simflow，随着网络技术的发展，许多以网络为基础的信息管理应用领域孕育而生并不断壮大。因此，将工作流概念引入到管理信息系统中．本文首先介绍了Simflow的工作原理，它采用自定义流程XML文件和步幅XML文件分别表示工作流过程和活动，然后通过引擎对XML文件进行解析处理，完成一个业务流程。然后进一步说明Simflow内部定义了很多模块，在工作流管理系统之中，多个模块之间通信是必须的，引出JMS概念，并且详细说明了Simflow如何使用JMS来实现模块之间的通信。

A Simflow WFMS based on JMS

A Simflow WFMS based on JMS is discussed in this article. With the development of network technologies, many application fields on information management based upon networks have emerged and tend to be mature. Therefore, introducing the concept of workflow into MIS is rather important. Firstly, the principle of Simflow is introduced. Workflow processes and their activities have been represented as the custom Process XML Files and the Step X ML Files in this system respectively. Then the XML file is parsed and executed by workflow engines. There are many modules in Simflow. The communication between the modules is very important. So JMS is introduced, and how to apply JMS in Simflow to realize the communication between modules is specified in detail.
