Abstract Currently, many enterprises have not an overall planning during information construction, which results in the appearance of a great deal of information islands and business process islands in enterprises. Information can not be shared effectively. Moreover, business process collaboration and automation can not be achieved. Then enterprise application integration (EAI) appears. Nevertheless, the development of dynamic e-commerce puts forward higher requirements for EAI. Enterprises not only need to integrate internal and external application system to support current business operation, but also demand a integration system which is flexible, easy to expand and change to support continuously changing business logic. Therefore, EAI expands to a wider area. In this case, because traditional complex system interface application integration mode can not adapt to the dynamic change of enterprise application requirement, it has not been suitable to current business situation, especially to business process management systems whose requirements change frequently. More effective and flexible development and integration mode is needed to meet the requirement of dynamic e-commerce. The appearance of service-oriented architecture (SOA) fills the vacancy. With the feature of loosely coupled and message-oriented request-response communication mode, and process concerned characteristic, SOA meets the requirement of enterprise to rapidly construct flexible integration application. The paper through to based on the SOA constructions middleware application integrations research analysis, the union middlewares application in some astronautics ground system , has established initially based on the SOA construction middleware application integration processing model.The paper in the analysis middleware characteristic foundation, according to the thought of faceing to the service that has designed based on the SOA construction middleware system construction, described the middl
