The Research And Application On Improving Service Component Architecture

In this paper, after intensive analysis and study of Service Component Architecture(SCA),a number of limitations in SCA have been proposed. By using OSGi technology, the isolation concerns of SCA run-time components, service registration, service life-cycle management, and the construction of SCA standard container have been improved. The overall design and layered architecture are also showed. This improved framework solves the problems of difficulty integration, low efficiency, high coupling and poor dynamic of traditional frameworks, achieves the purpose of improving flexibility and dynamic of the system and making the application integrations easier. Then, the implementation procedure based on this improved architecture is illustrated in detail. Practice demonstrates that the improved SCA designed by this paper can be applied for better system integration, and it is platform-independent, dynamic, easy to expand and maintain. After all, new experience and new method of service-oriented architecture based on the practices are summed up,and the developed orientation and researched work of SOA in the future are forecasted.
