Notice of RetractionDesign and Implementation of Distributed Workflow Engine Based on Java EE Platform

Workflow Engine is the core component of Workflow Management System. According to the standards of Workflow Management Coalition, this paper uses Petri net as the principle model, divides the Engine system into five functional modules,adopts Java EE Distribute Object Computing technique,thread poll control mechanism and BeanShell script interpreter technique to give the design and implementation solution of each module,which make it have the more obvious advantage in the application performance,resource utilization,scalability and supporting heterogeneity and distribution.
