Research And Realization Of Workflow Management System Based On WebService

The traditional government affair OA system, the control of business process always adopt the mode of hard cording that made the coupling of process handling code and business logic code, the thing bring on low efficiency of software development and the system answer business process change difficult. These obvious limitations made software trade difficult to reply our country's electron government affair and rapid development of OA; workflow is the important technology to separate process control.In this paper, a workflow management system is designed and implemented at the base of sufficiency research of WFMC (Work Flow Management coalition) reference model, the demand collection of information item of the public prosecutor office, and at the support of mature technology as J2EE and JBoss jBPM (Java Business Process Management) etc. Firstly, author put up several flexible rebuild to jPDL(JBPM Process Definition Language) bases the demands of process of case handling, realize the strong expansibility task list processor; also, designed the important function module such as process service,process monitor,process rollback and process release etc.Then, author analyzed the limitation of workflow system in existence, it's the weak interactivity of traditional workflow, can't solve the problem of transfer and expression of data in distributed and different environment, it's difficult to satisfy the requirement of Integration of business process in old systems. The technology or standard of Web Services, XForms, EJB and JBPM are researched in this paper, at last a framework of interactive interface integrated with Web Services and can extend to sustain multi-long-distance mechanism is put forward in this paper.The framework of interactive interface based on Web Services bring forward in this paper not only enrich new thought of research at workflow interface, but also bring up expansive betterment space for traditional workflow. The mostly function model's design and implement scheme already successfully apply to two project of the public prosecutor office and court, not only improve productivity of software, but also advance satisfaction of consumer. So that the paper has the theory meaning as well as the strong practicality value.
