Programming Web Services with Perl
There are currently two object-oriented modules for Perl that provide support for developing SOAP client/server applications: SOAP and SOAP::Lite. This chapter introduces these two modules. By comparing and contrasting the modules, you”ll learn their strengths and weaknesses. The last part of the chapter covers other SOAP-related utility modules, which either augment the client/server SOAP modules or add SOAP-related functionality to other packages and systems. By the time you finish this chapter, you”ll be able to develop basic SOAP applications with the toolkits and utility modules and make an informed choice of software to use in your SOAP projects.

- Web Client: a program that consumes (uses, interacts with) a web service
. Could be a Web Form, a Windows Form, or even a command line application

Apple - Web Services Core Programming Guide
Web services provide web-based APIs to support machine-to-machine communication over networks. Because these APIs are web-based, they inherently support interaction between devices running on different architectures and speaking different native languages. Common examples of web services include weather forecasts, stock market quotes, and book inventories. A server with a database responds to remote queries for data, where the client specifies a particular city, stock symbol, or book title, for example. The client application sends queries to the server, parses the response, and processes the returned data.

XML-RPC and SOAP Programming Guide
XML-RPC and SOAP Programming Guide describes how to use Apple Script and the Apple Event Manager in Mac OS X to make remote procedure calls using the XML-RPC and SOAP (Simple Object Access Protocol) protocols. XML-RPC is a protocol for using XML and HTTP to make remote procedure calls over the Internet. SOAP (Simple Object Access Protocol) is a remote procedure call protocol designed for exchanging information in a distributed environment, where a server may consist of a hierarchy of objects. This book describes only how to send XML-RPC and SOAP requests, not how to serve them.
