Enhancing Workflow Management System Based On Webservices

Traditional Workflow Management Systems (WfMS) is hard to meet the requirements of the dynamic, flexible modern business process. In recent years, Web services technology has been developing. It’s not only makes the activity in workflow by Web services form, but also workflow itself is invoked by Web services, especially semantic web services technology is developing, which makes it possible to compose automatic Web service workflow. This paper proposed a flexible workflow management system based on Web services. We propose workflow engine that handles the overall process flow, calling the appropriate web services, combines two or more web services in dynamic manner and determining the next steps to complete. We also present the design and implementation of a distributed web services workflow system. Workflows are usually used in human-to-human business applications. This means that a task is performed by different users. Information need to be distributed from one employee to a colleague, a customer or a partner. A business application manages these kinds of processes and takes care about messaging, security and the documentation of the whole business process. The Workflow offers an easy to use technology to simplify the development of these kinds of BPM (Business Process Management) solutions. It fulfills the requirements to a scalable, reliable, transactional, robust and simple deployable Java EE Workflow System. Keywords— workflow management system, Workflow engine, reliable services.
