Editorial Reviews:
Web services, the new way of stitching data and processing resources together to form elaborate, distributed applications, aren't like other software systems. They differ even from other architectures for distributed applications. In his fantastic Understanding Web Services, Eric Newcomer helps his readers figure out what Web services are all about. This book is better than any other book out there in helping readers come to grips with the terms, technologies, behaviors, and design requirements that define the Web services universe. It's remarkably light on code--Newcomer's logic appears to be that you should dig into the details of implementation only after you thoroughly understand the design concepts--and emphasizes definition and exposition of SOAP, UDDI, WSDL, and ebXML.Newcomer's work looks and reads almost like a notebook, with succinct statements in the margin (for instance, "SOAP processors first have to check the mustUnderstand attribute, if any"), adjacent to paragraphs that go into greater depth. He's careful to call attention to differences among the relevant standards documents, and points out differences among implementations. Graphical learners may wish for more conceptual diagrams, as there aren't a lot of them here. Newcomer's prose is brilliant, though, and it's pretty easy to determine what he means. Perhaps best of all, Newcomer isn't cheap with his opinions and forecasts. It's helpful to read his informed feelings and predictions. --David Wall Topics covered: The specifications, implementations, and popular trends that define the Web services movement. Conceptual coverage of Extensible Markup Language (XML), Simple Object Access Protocol (SOAP), Web Services Description Language (WSDL), and the Universal Description, Discovery, and Integration (UDDI) protocol fills these pages. Emphasis is on how it all works rather than on how to program for it.
Web services enable the new generation of Internet-based applications. These services support application-to-application Internet communication-that is, applications at different network locations can be integrated to function as if they were part of a single, large software system. Examples of applications made possible by Web services include automated business transactions and direct (nonbrowser) desktop and handheld device access to reservations, stock trading, and order-tracking systems. Several key standards have emerged that together form the foundation for Web services: XML (Extensible Markup Language), WSDL (Web Services Definition Language), SOAP (Simple Object Access Protocol), and UDDI (Universal Description, Discovery, and Integration). In addition, ebXML (Electronic Business XML) has been specified to facilitate automated business process integration among trading partners. This book introduces the main ideas and concepts behind core and extended Web services' technologies and provides developers with a primer for each of the major technologies that have emerged in this space. In addition, Understanding Web Services summarizes the major architectural approaches to Web services, examines the role of Web services within the .NET and J2EE communities, and provides information about major product offerings from BEA, Hewlett-Packard, IBM, IONA, Microsoft, Oracle, Sun Microsystems, and others. Key topics include: XML facilities for structuring and serializing data How WSDL maps services onto communication protocols and transports WSDL support for RPC-orientedand document-oriented interactions SOAP's required and optional elements Message processing and the role of intermediaries in SOAP UDDI data formats and APIs How ebXML offers an alternative to Web services that supports reliable messaging, security, and trading-partner negotiations With Understanding Web Services, you will be well informed and well positioned to participate in this vast, emerging marketplace.

 good but old
This title is very good for understanding basic WS technologies. But is older for now and some informations are outdated. Reprint with updated information (espec. UDDIv3) would be good.  Good Book
As a glosary is very good, if you where aming to learn how to program a web service it was not very good for me. I would prefer more code samples from the basics to advanced. Definitely you should have a previous knowledge of XML, and maybe even some basic knowledge of webservices before reading this. Excellent Overview, But Extremely Difficult Read
I recommend this book for everyone beginning Web Services. However, I do so with a word of caution: READ IT SLOWLY AND READ IT TWICE. The book has a great spread of issues but is extremely difficult to sit down and read/work through.
All the issues covered are covered lightly with the exception of the most important topics: WSDL, SOAP, UUDI and ebXML. The only thing it didn't touch on that I wish it would have was REST.
Key pieces of these topics are scattered and you need to be careful to read through and keep notes about where you can find more information (I found myself keeping margin notes on where key pieces of information were in the book at the introduction of each topic).
I recommend it so that you can understand the complexity and get a good overview of the topic, but I would definitely say that the book is only a good place to begin. It will leave your head spinning, but if you have purchased other books on individual topics, it will provide you with a reference on how they tie together.
The book has its ups and it has its downs, but it is worth reading.  A lot of understandble and useless paragraphs
We bought this book trying to find a good overview about what web-service implementation is, what WSDL means what RPC/Document style means, etc, by an expert point of view, I must say at least this is not the case.
There are a lot of paragraphs with useless information, that in the first read you avoid because you don't understand, in the next reads you avoid because they are useless.
Terms are confusing and mixed up, explanations also.
If you like skipping paragraphs it is a good newbie introduction, if you have some background on web-service just avoid it.
Really disappointing Pretty good overview
This book provides a pretty good overview of web services--although it's a little heavy handed with xml. Bottom line is that i6t would be easy to wal away from this book thinking web services is simply xml schema--and miss the bigger picture. More Customer Reviews:
