Jetspeed Enterprise Information Portal And Application

With the development of today's enterprise information technology, the enterprise information gateway (EIP) has already become one of domains which the enterprise most paid attention to。 The so-called gateway is based on the web system, provides the sole entrance to visit backstage application procedure and resources from different origin, and become a tendency where enterprise and government integrate information together. Its technical characteristic is to take the user as the center, to integrate enterprise application, to provide the personalization service for user and to realize the information centralism visit.Jetspeed is an enterprise information gateway realization of open source code the Apache organization develops. It takes Turbine as the foundation frame and provides the massive standard pattern plates mainly with technologies of Java, XML, etc.This article first divided the enterprise information gateway into three layers according to its characteristic, and separately carried on the detailed analysis to component and the function in three-layers.Then article introduced construction technology which the enterprise information gateway needs, and discusses unique two cores technology in the gateway - Portal technology and the Portlet technology. From aspects of principle, system structure, implement mechanism, deployment and so on, it carried on the detailed elaboration and produced the development example.Through comparing each kind of gateway software, this article chose Jetspeed to take the gateway platform because of Jetspeed's openness and excellent performance. Then it realized a concrete enterprise information gateway by studying Jetspeed principle and the system structure designs.Then the article research system integrity and SSO in detail accordingto EIP requirement, put forward a solution based on common integrated classification platform and SSO based on agent, and discuss the realization.Finally, the article took the system - change release subsystem of a gateway service as an example. Elaborated this system's development, realization as well as integration, and has established results in the enterprise information gateway.Summarily, this article realizes the Jetspeed gateway and integration. Following is the merit: The massive developments pattern, and easy to carry on the expansion. It is conveniently to increase, delete, replace, and renew service module. This gateway realizes the general application integration to integrate the external system by the general modular form outstandingly, and enables the user to experience the "one-stop" work style service truly.
