The Research And Implementation Of Workflow Engine Under The EMA Platform

Computer technology is used in the government department and enterprise broadly in these days.As requirements are changed regularly,the business folws are often changed.EMA is a good methods to solve these problems.workflow technology provides a method to solve these problems and integration of workflow technology. Software platform is important to solve these problems.We analyse the related standard of workflow and the application requirements.We designs a Workflow Management System basd on EMA. At first , this paper analyzes standards and some products of workflow .Secondly this paper brings forward an architecture and a designment method of web workflow management system on the EMA platform.For workflow engine is the core module of the whole system,this paper discuss the structure of workflow engine,the designment of interface between engine and the web application,including some important implemented issues such as J2EE technology and XPDL language.Finally,we apply an example about workflow engine,and show the usability of the system.
