【摘要】 随着Internet技术的迅猛发展和分布式应用系统在电子商务、电子政务应用中的日渐普及，各种各样的新兴分布式对象技术不断涌现。其中发展比较完善的有CORBA，DCOM和J2EE技术以及目前新兴的Web Service技术。 本文对基于Web Service技术的分布式应用系统做了较深入的研究。首先从分布式应用系统的形成、发展谈起，简要介绍了三种当前主流的分布式技术：CORBA、DCOM和J2EE，并比较了它们的优劣；接着介绍了电子业务当前的发展趋势，在该趋势下采用以往的分布式技术有何技术上的缺陷，以及Web Service技术在解决这些缺陷上有什么先天性的优势。 然后重点介绍了Web Service技术，从Web Service技术的起源、发展、系统框架、组成部分等几个方面分析了Web Service应用系统框架。接着介绍了Web Service技术中的三种关键技术(SOAP，WSDL和UDDI，其中SOAP负责Web Service的方法调用、数据传输；WSDL负责描述Web Service的功能：UDDI则负责注册并管理己注册的Web Service)，以及它们之间的关系与各自在Web Service中的作用。 最后以作者本人参与的移动计费系统为基础，在分析了该系统的特点后，论述了为什么要采用Web Service技术，以及采取Web Service技术的好处。并由此提出了一种高性能、高稳定性的企业级电子商务(政务)平台的解决方案。论文的最后总结了目前Web Service技术的不足之处以及Web Service技术的发展方向。更多还原

【Abstract】 With the rapid development of internet and the popularlarization of application of distributed applicated system in e-business and e-politics,kinds of technology of distributed object come out continuously , well developed ones of them are CORBA, DCOM, J2EE and the new developing Web Service.Deep analysis of distributed applicated system based on Web Service had been made in this article.Firstly, from the formation and development of distributed applicated system ,three kinds of current main distributed technology: CORE A,DCOM,J2EE were simply introduced,and the comparation of them was made.secondly,current developing direction of e-business was introduced,the shortcoming of old distributed technology in this direction and the favor of Web Service in these shortcoming were discussed.The main introduction of frame of Web Service applied system was made from the source, development, frameof system and composition of it. And then three kinds of key technology of Web Service: SOAP, WSDL, UDDI and the interralation of them and the respective effect in Web Service were discussed (SOAP take charge of method ,data transmittion;WSDL discripts competence of Web Service ;UDDI manages registration and registed Web Service).On the basis of mobile fee system that author took part in, after the analysis of charactics of this system the cause of application of Web Service and favor of application of Web Service are discussed. Based on this a high property, highly stable erterprise e-business (politics) plat solution. At the end of this article shortcoming and scope and the developing direction of Web Service were discussed.更多还原
