A Web Service is business logic accessed via standard Internet Protocols such as HTTP, SOAP
, and WSDL. There is really nothing magical about them and the concept is plain ole RPC but it is just happening to catch on this time. Since a Web Service is accessible over standard protocols they can be used to integrate between disparate environments. In other words a Java
Web Service can be accessed by a .Net Client and vica versa.
I suggest getting a copy of Java Web Services
by Dave Chappell(Sonic MQ) and Tyler Jewell(BEA).
