Enabling Technology: A J2EE based Business Process Management System for BPEL and Web services based business processes
Web services and BPEL (Business Process Execution Language for Web services) allow both, the description of business processes, and the description of the interaction between these business processes and their partners. Business processes run within Workflow Managements Systems. Based on the foundation laid out by Web services and BPEL, this paper describes the implementation of a Workflow Management System. To satisfy the requirements of today´s business world, a Workflow Management System has to support long-running, interruptible business processes as well as short-running business processes, both with a multitude of different Quality-of-Service (QoS) characteristics. Workflow Management Systems have to be robust, secure, and highly available. This paper discusses the implementation of a J2EE-based Workflow Management System that delivers on these requirements. The discussion involves the use of message queuing systems and relational databases when implementing the Workflow Management System, as well as its integration into a standard application server architecture, and the use of the services provided there like transaction manager, EJB container, people directory, and deployment infrastructure.
