Programming Web Services with XML-RPC

XML과 HTTP에서 사용하는 간단하면서도 강력한 XML-RPC를 사용하면, 개발자는 다른 컴퓨터에서 운영하는 프로그램들을 큰
노력 없이 연결할 수 있다. 즉 자바 프로그램과 펄 스크립트를 연계할 수 있으며, 다시 펄 스크립트와 ASP 애플리케이션과 연계할 수
있다. XML-RPC를 사용하면, 개발자는 다른 쪽의 컴퓨터 시스템이 무엇이건 간에 기능에 접근할 수 있으므로 웹 서비스를 쉽게 만들
수 있다.

Have you ever needed to share processing between two or more computers
running programs written in different languages on different operating
systems? Or have you ever wanted to publish information on the Web so that
programs other than browsers could work with it? XML-RPC, a system for
remote procedure calls built on XML and the ubiquitous HTTP protocol, is
the solution you've been looking for. 

Programming Web
Services with XML-RPC introduces the simple but powerful capabilities of
XML-RPC, which lets you connect programs running on different computers
with a minimum of fuss, by wrapping procedure calls in XML and
establishing simple pathways for calling functions. With XML-RPC, Java
programs can talk to Perl scripts, which can talk to Python programs, ASP
applications, and so on. You can provide access to procedure calls without
having to worry about the system on the other end, so it's easy to create
services that are available on the Web. 

XML-RPC isn't the
only solution for web services; the Simple Object Access Protocol (SOAP)
is another much-hyped protocol for implementing web services. While
XML-RPC provides fewer capabilities than SOAP, it also has far fewer
interoperability problems and its capabilities and limitations are much
better understood. XML-RPC is also stable, with over 30 implementations on
a wide variety of platforms, so you can start doing real work with it
immediately. 

Programming Web Services with XML-RPC covers the
details of five XML-RPC implementations, so you can get started developing
distributed applications in Java, Perl, Python, ASP, or PHP. The chapters
on these implementations contain code examples that you can use as the
basis for your own work. This book also provides in-depth coverage of the
XML-RPC specification, which is helpful for low-level debugging of XML-RPC
clients and servers. And if you want to build your own XML-RPC
implementation for another environment, the detailed explanations in this
book will serve as a foundation for that work.
