Foreword
This book is for the skeptics. In 1996, the skeptics thought the Java platform would have inadequate
performance for Internet and intranet servers. But they were proven wrong: Thousands of scalable Java
technology−based servers are now online. In 1997, the skeptics said that Sun's community
consensus−building process could not compete with established standards processes to produce a viable
platform. But it didwith an overwhelming groundswell. In 1998, the skeptics said the J2EE platform would
be too big and complicated to implement, and that Sun would be unable to get others to adopt it. But it was
widely adopted, and the design proved very powerful. In 1999, the skeptics said the J2EE platform would
come out years late, that it would take too long to complete specifications, a reference implementation, and a
compatibility test suite. But the J2EE platform came out right on schedule at the end of the year, with all these
deliverables. In 2000, the skeptics said that vendors wouldn't take the compatibility tests seriously and would
not implement the J2EE platform in their mainstream products. But they did; all the leading vendors became
J2EE licensees, and over twenty vendor products have already passed the extensive J2EE compatibility test
suite. In 2001, the skeptics questioned whether real enterprise applications would be implemented and
deployed successfully on the J2EE platform. But they have been. This book is the proof.
This book is for the optimistsdevelopers, engineering managers, CTOs, CEOs, and others who will have the
foresight to bet their enterprise on a promising state−of−the−art platform that can put them ahead of their
competition. In this book, these people will find examples that will help them design their own solutions, and
case studies to demonstrate to their colleagues that J2EE is a powerful, proven platform. There have been over
a million J2EE platform downloads from Sun since its release a year ago, not to mention thousands of
customers who use J2EE−compatible products from one of the two dozen vendors that have licensed the J2EE
platform to date.
This book is for those who want to better understand the J2EE platform. It demonstrates the most important
feature of the platformthat it is an industry−wide initiative, with support and contributions from many
companies and many people. The J2EE platform is not one product from one company. It's a standard
framework around which the leading enterprise vendors are competing to build innovative,
high−performance, distributed enterprise software platforms. In the pages of this book, you will find
contributions from BEA, IBM, iPlanet, Oracle, and half a dozen other vendors, as well as their customers:
AT&T, Bekins, CERN laboratories, the U.S. Army, and many others.
This book is for all the people who are already involved with the J2EE platform. The success of the platform
is the result of outstanding work and vision from a lot of people. I would personally like to thank those
people. In this book, you will read about the most important of themthe people who took the J2EE platform
into the trenches to solve business problems and reap the benefits of this new technology. Their experience is
enlightening. The book's editors, Rick Cattell and Jim Inscore, are ideally suited to bring these experiences to
you: Jim has managed all the technical writing for the J2EE platform, and Rick was instrumental to the
inception and technical architecture of the J2EE platform. We hope you enjoy reading the book as much as all
these people enjoyed working with this technology.
