Key words: Aiming at the problems of current academic libraries management systems based on Web without business service ability, which is not suitable for the joint construction and sharing of information resources, a J2EEbased solution is introduced. On the design of concrete pattern, the presentation layer is constructed by application controller, the business logic layer is constructed by session facade and service locator and data persistence uses value object. Beanmanaged persistent as model is emphasized. The development of pattern is illustrated through implementation process on layers.
