Workflow Model Based On Petri-net And Its Implementation On J2EE Platform

Workflow technology, as a new research field, has being widely appliedin the fields of manufacturing, office automation, concurrent engineering,electronic government and so on. It is the key technology to realize modeling,optimizing, managing and integrating of enterprises' business process and alsothe automation of business process. The workflow technology has become animportant method to smooth the business process and improve thecompetitiveness of enterprises.Petri Nets System is an advanced tool to describe asynchronies combutingmodel, since that time it has been studied in depth, and possess stapilitytheory basis andanalyses technology. A workflow model based on Petri Net canbe frankly examined and powerful supported a model of workflow process, soit can be provided distinct and correct.This paper researches the application of Workflow technology in OfficialDocument System, according to the actual conditions, Petri-net was chosen asa tool for Workflow modeling, and its route structure and trigger mechanismof Workflow were introduced to the modeling course.The paper dissusses the model's realization on the J2EE framework thedatabase design, user interface design and system security design. The paperdiscusses the key technology and the realization of the system, including therealization of the Struts framework and also including other key techniquesand the whole structure of the system.The paper also summarizes the conclusion and the characteristic of thesystem, points out the deficiency of current system and bring forward someimproveing idea.
