Introduction

It seems like only yesterday that I was sitting behind a computer terminal writing my first book for Prentice Hall. The book, titled UNIX for Programmers and Users, was released in 1993 and is still going strong. During that period, I was getting involved in distributed computing for the first time, and wrote simple C programs that used sockets to send data back and forth on a network. My first experience of network programming was so exciting and powerful that I decided to dedicate the last chapter of my UNIX book to a concept called The Grid, a term that I gave to a pervasive global network linking all computers, from mainframes to cell phones. Here is one of my favorite quotes from the book:

"Home appliances, cars, industrial robots and other machines will all be part of the Grid. In other words, everything will talk to everything. Resources and their interconnectivity will be greater than ever before. The theme of the 21st century will be collaboration."

Because the chapter was a bit off topic, and the Internet was virtually unknown in 1993, Prentice Hall removed it from the second edition of the book. Funnily enough, the quote is now perfect for this introduction to my new book on web services-a technology that is sweeping the computing industry and will forever change the way we think about distributed systems.

It gives me great pleasure to continue what I started to write all those years ago, and to provide you with a good understanding of the next logical step in the evolution of distributed computing.Sincerely,
Graham Glass
August 2001 How to Use This Book

The chapters progress naturally from web services basics to futuristic advanced stuff.

Chapter 1 provides an introduction to web services and describes the main concepts and terms. It's a great way to get acquainted with the topic, and can be used as a stand-alone primer before going to a web services presentation or conference.

To get hands-on experience, proceed to Chapter 2 which guides you through the process of building and invoking a simple web service. This chapter also shows you how to access and manage web services from a web browser, as well as perform common tasks such as aggregation.

Once you've seen how easy it is to create a web service, you'll want to read Chapters 3 through 6, which cover more advanced topics such as Web Services Description Language (WSDL), security and Universal Description, Discovery, and Integration (UDDI). Each of these topics is explained with the help of hands-on examples.

Chapters 7 through 9 show how the popular .NET and Java 2 Enterprise Edition (J2EE) platforms support web services, and how you can build systems that incorporate web services written using both of these technologies.

The final chapter offers a glimpse of where web services is going, with a discussion of the trend toward decentralization and peer-to-peer computing.
