The web services architecture provides a new way to think about and implement application-to-application integration and interoperability that makes the development platform irrelevant. Two applications, regardless of operating system, programming language, or any other technical implementation detail, communicate using XML messages over open Internet protocols such as HTTP or SMTP. The Simple Open Access Protocol (SOAP) is a specification that details how to encode that information and has become the messaging protocol of choice for Web services. Programming Web Services with SOAP is a detailed guide to using SOAP and other leading web services standardsWSDL (Web Service Description Language), and UDDI (Universal Description, Discovery, and Integration protocol). You'll learn the concepts of the web services architecture and get practical advice on building and deploying web services in the enterprise.This authoritative book decodes the standards, explaining the concepts and implementation in a clear, concise style. You'll also learn about the major toolkits for building and deploying web services. Examples in Java, Perl, C#, and Visual Basic illustrate the principles. Significant applications developed using Java and Perl on the Apache Tomcat web platform address real issues such as security, debugging, and interoperability.Covered topic areas include:
- The Web Services Architecture
- SOAP envelopes, headers, and encodings
- WSDL and UDDI
- Writing web services with Apache SOAP and Java
- Writing web services with Perl's SOAP::Lite
- Peer-to-peer (P2P) web services
- Enterprise issues such as authentication, security, and identity
- Up-and-coming standards projects for web services

This book is hard to fathom. The examples don't work. They would have been great if they worked. There is no overview; the big picture of the process is lost in a multitude of details. I usually love O'Reilly books: this is an exception. On the positive side, it is nice that there were full blown web service already coded. To bad they didn't work right out of the book.
This book has everything you need to understand and get a web service up and running using SOAP with one exception; thorough explanations. I found the examples in the book too terse and too many errors. The O'Reilly web site has plenty of errata entries under the 'unconfirmed' column and virtually no errata under the 'Confirmed' column (A misspelling of one of the author's name). Shame on O'Reilly for releasing a book before it was finished. If the book was finished, shame on the authors this work. If you're a pure Unix geek who abhors GUI interfaces, sticks to the principle, 'No one should read your code unless they understand it', well, then you'll love this one.
