Introduction to Web Services
Maydene Fisher
WEB services, in the general meaning of the term, are services offered via the Web. In a
typicalWeb services scenario, a business application sends a request to a service at a given URL
using the SOAP protocol over HTTP. The service receives the request, processes it, and returns a
response. An often-cited example of aWeb service is that of a stock quote service, in which the
request asks for the current price of a specified stock, and the response gives the stock price. This
is one of the simplest forms of a Web service in that the request is filled almost immediately, with
the request and response being parts of the same method call.
