Research And Implementation Of Service Generation System Based On BPEL

Nowadays,as SOA has increasingly gained wide recognition and application, service composition has be an important way of business process development. The service generation system can improve the developing efficiency of business process developers, and provides a more useful approach to reuse business processes.At the beginning, this paper introduces the background of SOA and the basic concepts of BEPL.Then it analyzes and concludes the defects of BPEL when developers need to reuse BPEL processes to compose new processes.In order to meet the shotfall,this paper advances a reuse mechanism based on template to extend the BPEL specification.Then the paper gives a detailed description of the system design,which is divided into several aspects,such as template generation,template composition and template export.Depending on Plug-in development techniques of Eclipse platform, Business Process Generation Platform,based on EMF (Eclipse Modeling Framework) to build system model,uses the GEF (Graphical Editing Framework) technology to implement a visual development environment of business process generation.
