The Research And Implementation Of Web Services Based On J2EE Platform

On the basis of detailed analysis of Web Services technology,this paper describes the design and realization of a Web Services Framework(WSF) based on J2EE, it has realized the basic service creating, maintaining, publishing and invoking function.The target of this framework is that making the development of service components orient service in the most extent .To the given requirement, we can seprate it into some independent smaller services using service-Oriented idea, and developing them on the WSF.For WSF has provided the maintaining and invoking mechanism of services, these work does't needed to be done in our business services, which makes our service developping faster, quality and maintenance better. Besides, we have also realize the configuration function of service components in WSF, so we can rearrange the existed services into some other service components with new functions, thus the application systems we have developed have better loose coupling. Finally, all services based on WSF can publish and invoke through Web Services technology, so these services are independent on different platforms and are distributed. The above points of WSF make the development of applications based on service-Oriented more fast and simple and improve the loose coupling, reuse and expansibility of application systems.This paper also used study results—WSF in the realization of a research paper topics. Practice has proven use of the WSF framework based on J2EE platform will greatly shorten the development cycle, and the applications developed with a better loosely coupled.
