| The paper presents the present situation and the problem that lies in the development of midware . Then discuss some problem in GuangDong Integrated Business Support System(IBSS). The author uses J2EE technology which is one of the three major technology about midware to develop IBSS system in order to achieve the purpose of conformity and optimize campus information resource.In the process of the development, the author mainly uses two technologies: Component develop based on EJB, web services. In detail, EJB technology is used to implement the concrete business of IBSS system; and web services is used to deploy the application tier business to web services in order to let client to call.This paper builds the IBSS' s core database on the platform of 0racle9i DataBase, and realizes the tables and tables' relationships in the core database, which is the data layer component. Using the weblogic as the J2EE application server and EJB as the developing technology, this paper designs the data logic layer and business logic layer in the IBSS system, in which the entity bean is used to implement the system data tier, and session bean to implement logical tier. This is the application layer component in the IBSS system.Then the author introduces the character and the architecture of Web services technology, giving out the merits of this technology; The author also introduces the core technology which Web services will use, such as XML, SOAP, WSDL, UDDI etc. Thirdly, The author chooses J2EE as the implementation platform of Web services, introducing the development method of Web services on J2EE platform. In the last, the author sets up a private UDDI registration center based on Oracle UDDI registration center that provide the deploying and finding platform of web services.With the help of web services, the author resolves the problem of in the IBSS system, each system can communicate with others conveniently. And the same time, it provides a brand-new mode for some similar system.
