Considering the system requirements of virtual laboratory based on component composition technology, the business processing model of dynamic virtual laboratory, driven by workflow, is presented. The integration model of lightweight J2EE framework (SSH) and workflow system (Shark and JaWE) is introduced. The design and implementation method of dynamic virtual laboratory driven by workflow, based on lightweight J2EE framework, is proposed, and this paper analyzes the realization mechanism of virtual experiment project, the management approach of data and control flow, and the dynamic composition method of the experimental process. Lastly, the application case shows that this method is effective.
