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.
