Workflow Management Systems transform practical business processes into certain computerized forms and implement automation of business process by means of sequencing work activities and invoking appropriate human and information resources associated with these activities. They offer nice environments for cooperative works.More and more application systems adopt Web methods owing to the development of Web technique. This paper analyses the advantages and disadvantages of several architecture and designs a workflow architecture based on J2EE.As the core of workflow management system workflow engine directly affects the capability of the system. The paper designs and realizes a specific workflow engine using J2EE and XML techniques, it improves the implementation efficiency and expansibility of workflow.The engine regards database management system as the centre. Process definition, business datum and conversion of the state can all be stored in the related database, it improves the flexibility of development and the discovery of trouble, at the same time it improves the analytic efficiency of WPDL.The system adopts role-based access control for interaction joint. Different roles can only manage work lists correlating with themselves after they land the work list manager. This improves the security of the system.User can implement activities and modify status of activities in the work list manager, it improves the flexibility of the system.Client-side users land the system by means of browser to finish the work correlating with his role, it improves distribution and flexibility of the system.
