As the Three Gorges Dam has put into operation, it is necessary to develop a co-scheduling navigation system for both the Three Gorges Dam and the Gezhouba Dam. The Navigation Co-scheduling System for the Three Gorges-Gezhouba Dams aims at ensuring safe, convenient and smooth navigation of the ships passing through both dams. The design and implementation of the Navigation Co-scheduling System for the Three Gorges-Gezhouba Dams are described. The general situation and core requirements are analyzed, followed with the structure of the Navigation Co-scheduling System, which is developed under Sun Microsystems's J2EE Architecture. Then we mainly focus on core J2EE patterns and in detail show how those design patterns, such as Front Controller, Intercepting Filter, Service Locator and Data Access Object Factory Strategies, are used and applied in different layers.
