This book shows you how easy it is to create and use Web Services with IBM(r) Rational Application Developer or Web Developer, and WebSphere Application Server. Intended for novice to intermediate Java programmers, Developing Web Services for Web Applications teaches users how to create Web Services, deploy Web Services to a server, and create client applications that use Web Services. Each chapter of the book teaches a key Web Service concept and takes you on a detailed, guided tour for creating or using a particular Web Service. Even if you're completely new to Web Services, by the time you finish the lessons in this book, you'll have all the skills needed to create useful Java programs with Web Services. Using the "guided tour" approach, the book comes with practical step-by-step instructions and numerous screen captures, making it easy to follow along. While most books teach how to use either a development tool or a particular technology, Developing Web Services for Web Applications combines learning about Web Services with using Rational Developer tools.Each chapter develops a complete Web Service and/or application, with sample code and solution files provided on the accompanying CD-ROM.Also included in each chapter are additional exercises to help reinforce the concepts covered in that chapter. By the end of the tour, you'll be able to use Rational Developer tools to build your own Web Services, and you'll understand why Web Services are gaining popularity as a way to provide services across the Internet.Developing Web Services for Web Applications: * Is perfect for all skill levels, from those taking their first steps to those looking to explore more advanced topics * Teaches you Web Services concepts and terminology as you learn how to use the Rational Developer tools * Shows you how to create, deploy, publish, and use Web Services * Explores troubleshooting, using relational databases, using JavaServer Faces Web applications, adding security features, and much more Contents: Introduction Chapter 1: Creating your first Web service and Web application Chapter 2: Deploying and publishing your Web service Chapter 3: Discovering Web services Chapter 4: Handling Web service errors Chapter 5: Using databases, part 1 Chapter 6: Using databases, part 2 Chapter 7: Using Web services with JavaServer Faces, part 1 Chapter 8: Using Web services with JavaServer Faces, part 2 Chapter 9: Securing Web services, part 1 Chapter 10: Securing Web services, part 2 Appendix A: Installing WebSphere Express Index

What this book does is show how WebSphere can handle a lot of that behind the scenes boilerplate, and lets you focus on actually building [and debugging] the guts of a Web Service. By the way, the "Rational" programs described in the book are a renaming of earlier functionality build within WebSphere. Personally, I would just lump Rational back into WebSphere.
The book has the foresight to quickly start with a very simple example of a stock quote program. The raw data comes from a Yahoo site. Your Web Service sends a query with symbols of companies, and Yahoo returns a string with the prices, and elementary parsing extracts these. The book shows how WebSphere wraps your code, so that it can now answer a query from another remote application. Naturally, the text then goes on to describe how to make that application, with its requisite proxy code.
Some of you may have programmed client-server code in C or C++, using Remote Procedure Calls. There, utility programs like rpcgen would make the necessary proxy stubs for marshalling and unmarshalling the queries and replies. You should clearly understand that Web Services have moved away from that tightly coupled mechanism, and they use XML for data transfer. But at one level, you can simply and correctly regard what WebSphere does for you in such things as making the proxy code to be a much more elaborate, but equivalent, analog of rpcgen.
Others of you will have used WebSphere, or other JSP/Servlet containers, to make those types of applications, where the container would autogenerate various source code files and compile them. So what the book describes WebSphere doing for Web Services is a small conceptual step from work you have already done with WebSphere.
The book then goes into much more detail, by building out that example Web Service. Like how to detect and cope with Web Service errors. Or test a Service. Or tie the Service to a database. (Surprise, it's DB2!) All important. But, more broadly, you get an understanding of how WebSphere acts as the Web Service container. A major help to you.
The virtue of the book is that it demystifies Web Services, and shows how WebSphere can put this within your programming scope.
Congratulations to the author for coming out with such an excellent book. This book really has made learning about Web Services fun. I have completed only the first chapter and I feel that it is worth every penny I spent on this book.
This is refreshing because IBM redbooks are very boring with lot of theory and not enough practical examples. This book takes a different approach and does a very good job.
The first jsp page needs a try catch statement which the author did not mention. I hope there are no technical mistakes in other chapters. I will post an update to my review after I finish it.
The reason that is book is not that great is:
1. No Errata
2. No CD that has evaluation version of the Software
It is very frustrating when you encounter an error in the book and you send an email to the author and wait for a week for the response. I realize they have a life but if the author cannot even prepare an errata for the book and post it on the publisher's website or their blog then I don't think anyone should be spending their hard-earned money on this book.
It is better to do a search on google for RAD webservices tutorial. IBM site has some tutorials with videos that you can watch that walks you through the steps of creating web services.
The instructions shown on this book will work only on RAD 6.0.1. By the way it is impossible to upgrade RAD 6.0 to RAD 6.0.1 version. I have tried network installation, local installation and galaxy installation. Nothing works. For a book like this, it is very important that the tool is provided as part of the CD.
The CD that comes along with the book contains only code examples. Who needs the code examples when the RAD updater takes two days to download the zip file required to upgrade? I used T1 line believe me.
I have suffered due to this book. I hope this review helps others to avoid misery. God bless.
