Based On The J2ee Workflow Management System Design And Realization

Workflow management technology is a new technology that can control the workflow in the world and WfMC is the organization to study workflow management. Workflow Management System is the software to control and manage the workflow. As the fast e-business development in Internet, traditional workflow management systems (WfMS) can't meet the requirement of modern business process management any more. They don't provide enough support to dynamic and inter-organization business processes because lacking agility and interoperability. With the development of computer networks, our solution is to introduce one of the latest technologies to improve WfMS performance. With the development of web and related technologies such as java technology, the original computer architecture has developed from the 2-tied C/S architecture to the 3-tied B/S architecture,and been realizing the popular J2EE(Java 2 Platform Enterprise Edition)application architecture. The EJB-Based 3-tied architecture is one important part of J2EE application architecture. Published and discovered Web services through standard messages will add dynamic and interoperational features to WfMS. In this paper, the technology and reference model of workflow are introduced. The components and function of workflow reference model are discussed in detail. The design pattern of the workflow management system suited for General Software Framework Builder for Enterprise is put forward. According to the design pattern and J2ee criterion, it is based on EJB and JSP that the workflow management system is put forward and implemented. It gives many merits to the workflow management system, such as, good structure, the high adaptability to practical situations and the reuse of components, elicit the pages automatically. This paper is composed of seven chapters, and the designed WfMS is discussed in detail. In chapter 1 and chapter 2, we describe the status of WfMS firstly, with emphasis on the frame of WfMS. Then, the demand of enterprise is analyzed, followed by the discussion of the defects of the traditional WfMS.
