Product Description
Architecting Web Services is targeted toward developers and technical architects who have heard about, and even started to work with, Web services. The book starts with a background on the evolution of Web services and their significance to future collaborative efforts via the Internet. It then reveals the architecture for Web services and the various relationships that can be established through their consumption.
Following a short technical primer on XML and related technologies, the Web services model is outlined to illustrate the decisions that have to be made in the areas of presentation, interface, and security before the design is even started. Topics ranging from content to state management to system infrastructures are discussed to help you understand the options and the pitfalls when developing robust Web services.
The life cycle of implementing Web services from start to finish is illustrated, taking existing processes and exposing their functionality through Web services. Examples extend both Java and COM objects as Web services before exposing an entire hotel reservation system through a Web services workflow. These exercises are followed by three application scenarios that consume these Web services, again with both Java and Visual Basic/ASP examples. Discussions cover the design, implementation, and testing of each solution to ensure a successful result.
Finally, the book takes a look ahead at the future of Web services by examining both the current strategies of the primary vendors and the standards initiatives that are presently under way. A companion website provides all the source code, and hosts the Web services and sample applications introduced in the book.

This book is probably one of the worst technical books I have ever bought. I wonder if the editors actually read the text. The book starts off with an introduction to Web services which describes them using all sorts of confusing terminology. It uses phrases like sharing content, sharing processes, sharing information and then goes into presentation layers followed by business layers, and wastes 10 pages talking about what a shared process is. I eventually worked out that in fact all the author was trying to say is that a Web service acts like a Remote Procedure call with a request and response. This is simple and only should have required a few lines to explain. And in any case shared processes are nothing to do with Web services. Even worse the author then compares Web services to CORBA and says they both allow code re-use. Does the author know what CORBA is I wonder…The point he should have made is that Web services are stateless and CORBA is a pure inter-object protocol with object activation and sessions. They are not really comparable. The book gets much worse than this and delves into all sorts of meaningless diagrams about architecture. If you want to find out about Web services go to some of the good sites on the web, but don’t waste your money and more importanly time on this book.

This book is horrible. Save your money and buy a good book. Check out either Developing Java Web Services or Java Web Services Architecture.

This is not a book for technically oriented people looking for answers on web services. Questions you have on things such as scalability, security, and business models are either not covered or are glossed over at a 50k foot level. Little or no examples are given that will stand up to a developers scrutiny. There are no new ideas here. None. There are no solutions to the important questions here. None. This is yet another book in the “Expert’s Series”. I’ve bought a number of books recently by Apress. For most of these, I have wondered if the author learned the subject in order to write the book. I am convinced that this is the case here.

This book was so booring that I gave up after reading half of it. It gave me almost no useful information at all. I have not had any practical use of this book so far.
