Research And Implementation On Key Technology Of Workflow Based On J2EE

Since workflow technology appears ,It has become one of essential contents in the enterprise informationization construction plan. From simple office automation system's development, to enterprise ERP system's implementation ,The workflow technology has displayed quite importantly even is the essential function.J2EE is excellent enterprise application architecture. It is secure, highly scaleable, reusable and has a high performance. J2EE based workflow management system is a main solution in the enterprise business application, office automation, and electronic government applications.Based on the theory of workflow and J2EE technology, The prime task and the achievement are as follows:Based on the theory of workflow and workflow management system ,Present theJ2EE based workflow management model, And analysis this model connection and the module on the detailed. Fuses in the work class management system management system the J2EE technology and the MVC frame, proposed based on the J2EE work class frame .Use an open source workflow engine, OSWorkflow to implements the workflow management model. Uses the standard RBAC(Role Based Access Control) model to implements the workflow management system organization and privilege module. Build a basic class library for the workflow framework. Analyze the model's workflow controls and functions.This thesis use a real workflow management system use case to implements the J2EE based workflow management model. It is shown by the development and running effect that the workflow management system based on J2EE has good flexibility, interoperability and expansibility, and can satisfy the demands of more complex workflows.
