I wish I could recommend a better introduction to Java Web Services. David Chappell usually does a good job at explaining new technologies in simplified form; however, he falls short with this one. It comes very close to being a step-by-step, build-up tutorial but falls short. If you already know SOAP, perhaps coming from the .NET world and you just need to make the right connections in the Java world, then this would be a good book for you. However, if you don't know SOAP and you're looking for a thorough understanding of what's going on under the covers before you move on to advanced APIs, then this is not your best bet. Actually, I'm not sure what is. I started writing such a tutorial myself but got distracted by other projects. However, this book is solidly average, nothing necessary wrong with that, and if you can find it at a good discount it's a decent buy.

Makes it understandable...
This book covers the topic of web services, primarily from a Java perspective. It assumes a familiarity with Java and XML so as to be able to follow the code examples. The chapters are as follows: Welcome To Web Services, Inside The Composite Computing Model, SOAP: The Cornerstone Of Interoperability, SOAP-RPC, SOAP-Faults, and Misunderstandings, Web Services Description Language, UDDI: Universal Description, Discovery, and Integration, JAX-RPC and JAXM, J2EE and Web Services, Web Services Interoperability, and Web Services Security.
If you read the chapter headings and say "What does THAT mean?", then you probably have a reasonability good idea as to whether this book is for you. As stated in the preface, this is not a "For Dummies" treatment of web services. While it covers all the different technologies that make up web services, it does it at a pretty high level of detail with a lot of code samples in Java.
The good thing here is that many of the examples are given using the Apache Tomcat server as the mechanism for processing the request. This is great in that you can download that software for free from the Apache site. This book doesn't go into detail as to how Tomcat is set up and configured, however. You need to work through that on your own. Once you get to that point, you can use Tomcat to play with the examples that are used throughout the book. While they can look complex and intimidating, you can learn a lot from them.
As a Notes/Domino developer, I learned a lot by reading the book. Am I ready to start developing web services? Not hardly. But I do understand more of the concepts behind how they work. Since web services often use servlets to process requests, Notes/Domino 5 doesn't fit the traditional picture of the technology. But since web services usually involve SOAP XML statements sent to a server, there's no reason you couldn't program a web service in Domino as a web agent that runs when a user submits a web page or runs a URL that activates a server agent. The processing is done and then returned to the client as an XML page. Once you read and digest the basic concepts behind it all, it all starts to come together.
If you are a Notes/Domino developer who is trying to understand "web services", this book could be useful. The book gets progressively more complex and detailed, so you may find yourself skimming at the end. If you are to the point of being ready to run an implementation of a servlet and SOAP engine (like Tomcat), this book will help you get started with your understanding of web services.

Nice intro, clear layout
Not that dated, you will get the background that is behind all the hype and you will get some hands on. Not a first choice but it is a solid review and a book I still keep on my desk. Get this and of course one of the newer titles. The new ones may be hyping something that isn't going to happen, at least with this one you will find most of the topics still are the cornerstones of web services. There is gold in them there hills, and those hills are strewn with books discarded too soon as old. Many explain things very well and offer knowledge. Nice book.
