网络服务与简单对象访问协议

网络服务是基于网络的分布式应用程序的基本构造模块，这些程序是以平台，对象模型和多语言方式构建的，SOAP技术通过一种基于XML的，平台无关的方式集成现有的网络服务到应用程序中，它有助于实现大量异构程序与平台之间的互操作性，首先简要介绍网络服务的定义，以及建立基于网络的分布式应用程序所要解决的基本技术问题，然后说明SOAP是如何克服存在技术，（如CORBA和DCOM）的许多缺陷；最后通过一个实例，描述怎样通过SOAP调用现有的网络服务。

Web services and the simple object access protocol

Web services are building blocks for constructing distributed web-based applications in a platform,object model,and multilanguage manner. The Simple Object Access Protocol(SOAP) improves internet interoperability with an XML-based,platform-agnostic approach to aggregate the existing web services into applications.This article defines web services and the key enabling technologies of building distributed applications across the internet. And then describes the ways the SOAP overcomes many of the limitations of existing technologies,such as DCOM and CORBA. An example of how to call a web service through the SOAP is provided in the end.
