The Implementation Of Prototyping System Of Registry Center For Web Service Based On UDDI

During the development of Internet technology, the Web is a very bright pearl. It has become the mainstream technology in the recent years. The Web-based applications have absolutely taken up the leading statue in the Internet. As the evelution of Internet gose further, the Web-based applications have become more and more complex, and some traditional enterprise-oriented distributed computing and object-oriented technologies try to transmit to the Web.The evelution of traditional enterprise application integration has been hold back beacause of its high cost , complex technology and difficult implementation. Simultaneously, when the enterprise applications transmit to the Web, the distributed computing ocurres the huge obstacle, such as how to resolve the heterogenous platforms' communications, data exchange, access module and so on. So a new technology is needed to make enterprise applications to transmit to the Web smoothly. With the occurrence of XML, it completely enables the data representation and exchange between the heterogenous platforms. Underlied XML and W3C recommadations, IBM and Microsoft established a new Internet-based access protocoal named as Simple Object Access Protocol (SOAP). XML and SOAP led to web service born.Web service is a kind of reused component in the Internet. It can be invoked from the Web. As a new information integration technology, web service has made great progress in recent years. Its related protocoals have become accepted standards. In the protocol stack, Universal Description Discovery and Integration protocol (UDDI) enables find and publication of web service. Just like CORBA's Trader and Internet's DNS, a Web service registry center can be established based on the UDDI. The enterprise can publish or find some web services. So it is very convenient to realize information system's dynamic integration.After studied the UDDI Specification deeply, the author established a prototyping system of registry center for web service and implemented this prototyping system by Java. This paper addresses establishment and implementation of the registry center prototyping system. Following the introduction of distributed computing technology, XML and its protocol family are introduced briefly. Then the author discuss the definition, protocol stack and three roles' interoperation of web service in detail. The fourth section in this thesis turns to the author's research work. The author gives out the prototyping system of registry center for web service, presents every functionalmodule and related interfaces, and shows all the data types and the interoperation of the system. The 5th part describes the implementation and operation of registry center. This thesis ends with the summery and the future work.
