Eventually, Court managed xix Go back to the first page for a quick link to download this book online! And once he explained it, I knew that Trilogy had to do a degree turn, or Trilogy would lose their competitive advantage. You see, EJB is a specification for a server-side component marketplace.

EJB enables you to download off-the-shelf components from one vendor, combine them with components from another vendor, and run those components in an application server written by yet a third vendor. This means companies could collaborate on the server-side. EJB enables you to download, rather than build, ele- ments of server-side applications.

The EJB value proposition had strong ramifications for Trilogy. EJB represented a way for Trilogy to get out of this middleware business, and concentrate on their e-commerce strategic efforts. This would mean discarding the backbone com- pletely in favor of a third party vendors architecture.

Not only would this re- duce Trilogys maintenance costs, but it would solidify their software suite, since their middleware would now be written by professionals who had been in the business for twenty years. This proposition would eventually lead to an entirely new business unit forming at Trilogy. Back then, the specification was about a third of the size its grown to today.

Understanding the specification turned out to be much more challenging than downloading it. The specification was written for system-level vendors, and was not meant to be a tutorial for end developers. The section on entity beans, for example, took me a good two months to really grasp, as the notion of persis- tent components was new to me. This arduous struggle with understanding the EJB specification is what even- tually lead me to write this book for you.

This book represents everything I wish I had when I first started a year and a half ago. So what is this book about? This is not a book on EJB propaganda. Well, it may be more accurate to tell you what this book is not about. This is not a book on how to write EJB code on any single application server. This is not a nice book that paints a perfect picture of the EJB world. This is not an advertisement for any particular EJB product, nor a campaign to rid the world of Microsoft.

The goal of this book is to help you. I want you to be able to craft solid, secure, and scalable server-side deployments. As you read this book, youll learn how to design, implement, and deploy EJB solutions. This book covers both the vi- sion and the reality of EJB, and is written from an independent developers per- spective. I hope it will prepare you for the challenges you will face. I wish the grass was greener and I could write a book on how clean and por- table EJB is, but the truth is that this technology is not perfect, and you should Go back to the first page for a quick link to download this book online!

Preface xxi know exactly what the imperfections are. I will expose you to the gruesome and incompatible parts of EJB, and also explain how the industry is solving these problems.

Indeed, the newer specifications especially EJB 1.

I hope that by the time youre done reading this book, you are convinced that the vision of EJB is solid, and the future is very bright. To give you as much exposure to EJB as possible, almost every new concept in this book is complemented by a brand-new enterprise bean.

This is not a book with a single code example that flows for the entire text, because that would give you a very narrow view of the kinds of domain models you can build with EJB. So prepare yourself, because together we will develop thirteen enterprise beans over the course of this book. My hope is that I can save you time and energy, and aid you in designing well- crafted server-side deployments.

But this is merely the beginning. The EJB marketplace is just getting started, and theres a whole lot more work ahead to do. I encourage you to take an active role in the middleware industry, and to work with me taking EJB to the next level.

Feel free to e-mail me your experi- ences, tips, and design strategies, and Ill post them on the books accompany- ing Web site to share with others. Our goal is to increase our knowledge of EJB as a community, and together we can do it.

He has been actively involved with Sun Microsystems enterprise Java solutions from their inception, and has designed, built, and deployed a variety of enterprise applications, including architecting and developing complete appli- cation server products.

He routinely devotes a significant amount of time towards influencing and refining Suns enterprise specifications, is a regular contributor to middleware interest mailing lists, and regularly speaks at middleware-related conferences. Via on-site training courses, The Middleware Company educates developers and managers on the latest server-side technologies.

They also aid in the develop- ment of custom middleware solutions. Its about EJB concepts, T methodology, and development. Youll see many, many examples of Enterprise JavaBeans throughout this book, giving you a practical understanding of the subject.

Make no mistake about itwhat you are about to read is not an easy subject. EJB and J2EE incorporate concepts from a wealth of areas, including distrib- uted computing, databases, security, component-driven software, and more. Combining them together is a magnificent stride forward for the Java commu- nity, but with that goes a myriad of concepts to learn and understand.

This book will teach you the concepts and techniques for authoring reusable components in Java, and it will do so from the ground up. You only need to understand Java in order to understand this book. While youre reading this book, you may want to download the appropriate speci- fications, such as the EJB and J2EE specifications, available on the Sun Micro- systems Web site. See the books accompanying Web site for links to these specifications, as they complement this book nicely.

J2EE is huge, and it spawns a multitude of concepts. This means you only need to approach this book with understanding of the Java language because we will teach you everything you need beyond that.
