Research Of Web Services Application In Intelligent Uptown Information Service System

Web Services is a new distributed model. It is an application that is supported by those open criterions and technologies involving XML, SOAP, WSDL and UDDI. The purpose of Web Services is to construct a technology layer that are independent of platform or programming language on the basis of existing various kinds of different platforms. The application on all kinds of platforms relies on this technology layer to implement the mutual connection and integration. It is exactly this characteristic making Web Services an ideal solution of EAI.The intelligent uptown information service system is a platform from which residenters in the uptown can get comprehensive, rapid information service. The paper devotes to discuss how to realize dynamically integrating of the information service system for the intelligent district and the application system of service provider based on web Services, improve the systematic expansibility.Firstly, the paper introduces architecture of web services, and particular analyze the key technology of web services such as XML ,SOAP, WSDL, UDDI.Secondly, the modeles of the system are divided on the basis of requirements analysis and the architecture of system is completed. Web design pattern of Struts framework based on J2EE MVC model is adopted to design the whole system, which can split the application into business module, application controlling module and data displaying module efficiently so that the flexibility of program could be improved and the program could become easier for upgrade as well. Moreover, a agent layer of web services is constructed in Struts framework, and the agent classes in this layer are responsible for interacting with Web Services of service providers so that the intelligent uptown service system and application system of service providers could be interlinked and integrated.Lastly, the paper takes the realization of feast reservation as an example, introduces the development procedure of the whole system, and discusses concretely the application of web services in the intelligent uptown information service system. In this instance, the services of provider and the client parties for querying theinformation of feast and feast orders were implemented.
