Preface

I have been lucky enough during my career to have worked as a developer, a consultant, and for many years as a WebSphere Application Server (WAS) administrator. I have also held senior architecture roles. One thing I have learned is that it is difficult for one person to know everything about a complex product such as WAS 8. More often than not, we find ourselves struggling to find the right amount of time and patience, to learn all the intricacies of a new product.

WAS has now become a highly in-depth product, as has JEE (Java Enterprise Edition, formerly known as J2EE) on which WebSphere 8 is based. During this foray into WebSphere Application Server 8, I have kept in mind that some readers are new to WAS and require an overview which gives them a complete view of what the product entails, while others are seasoned and are looking for insights that are not so easily understood, or available through IBM's standard documentation.

It is a challenge for any author to provide detail and at the same time convey and allow for simple understanding. I believe that throughout this book you will be able to read and understand the topics presented with minimal effort. As you try the exercises and examples, you will gain more in-depth understanding and experience to support your administration of WebSphere Application Server 8.
