Web services have been advertised as the answer to enterprise application integration, reusability, and as a way to prolong the life of legacy applications. By developing applications as Web Services they become available (exposed) to other applications that use (consume) the service following open Web standards. These services can be exposed and consumed over an intranet, extranet, or the internet through standard Web technologies. These technologies include WSDL, an XML-based description format; SOAP, an application messaging protocol; and HTTP, a collection and transport protocol. We introduce our students to Web services with some simple examples developed using ASP.NET technology. The Web Service applications were created using Visual Studio .NET. The services were published to a .NET server. A Web application was developed using Visual Studio .NET to consume the previously created Web Services. The students are then assigned to develop a similar system to create and consume a Web service. A definition of Web Services and descriptions of the technology that is used to create, expose, and consume the Web Services will be provided.
