Chunsen Wang · Jisuanji gongcheng yu sheji · 2002
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.
