Web Service Publication and Discovery Architecture Based on JXTA

Abstract

The publication and discovery of web service is one of the most important issues in Service-oriented architecture. The common Universal Description, Discovery, and Integration (UDDI) still has some defects, such as register information can be invalidated since it is not able to update actively, its centralized approach leads to a high cost of server, and service providers can't delete register information in time when they stop to provide service. In this paper, first, a novel web service publication and discovery architecture based on JXTA is presented, which is applicable for internal enterprise. Then we make use of P2P network to publish and discover service, and propose distributed concurrent discovery mechanism to accelerate discovery speed. We also adopt a detector to discontinuously detect service, and update service information timely as well as remove unavailable service in the architecture. Finally, we prove that the proposed novel architecture can offer a good solution as well as can effectively resolve enterprise internal web service publication and discovery.
