In this paper, we explored the various complicated E-Commerce Applications enhanced by loosely coupled asynchronous communication. And then, we put forward the automatic modeling of E-Commerce based on the server-side component models. It fully leverages the various features of the underlying middleware services and meanwhile combines the dynamic modeling and coordination feature of workflow with the auto-generation and logic integration of the components. It realizes the faster development of workflow management system and also satisfies the demand of swift flexibility and extensibility on the business logic.
