Synopsis by Alan Zeichick

Once upon a time, Java was viewed as a language for building tiny Web

applications. No longer. With the rise of advanced standards such as JDBC,

Java can talk to nearly all relations or object databases; thanks to JNDI, Java

can access directory services; Sun's specification for Enterprise JavaBeans

allows developers to build distributed applications which can communicate

with each other; the Java Messaging Service provides for applications to

"publish" and "subscribe" to services, and so on. Java's time as a serious

programming platform has arrived, and this book provides not only a detailed

description of today's Java platform, but all of the enhanced specifications

mentioned above. Thanks to its clear explanations, this book is valuable for

developers or their managers considering the use of Java for enterprise-scale

applications. The inclusion of complete examples and source code makes it

even more valuable for current Java developers looking to understand all of

the capabilities unleashed by this new programming technology.

Back Cover

Stephen Asbury and Scott Weiner – two of Sun’s favorite Java programming

trainers – provide easy-to-digest instructions for the major Java Enterprise

APIs and their associated programming tools and products. They describe

proven techniques for combining these APIs to create powerful enterprise

applications and discuss the role middleware products play in the enterprise

development process. You’ll learn how to:

• Program with Java Enterprise APIs like RMI, Servlets, JDBC, JNDI,

JTS, and others

• Build N-Tier transactions applications with Enterprise JavaBeans

• Create messaging applications with Java Messaging Service (JMS)

• Build a servlet search engine for your Web site

• Create an online store with JavaServer Pages (JSP)

About the Authors

Stephen Asbury and Scott R. Weiner are cofounders of Paradigm Research,

Inc., a training company that specializes in object-oriented programming with

Java, JavaScript, and other Web technologies.

Dedication

For my friends and the lessons they taught that were sometimes hard to learn.

—Stephen Asbury

For my wife Susan, who is special in too many ways to list here. For my daughter Emily,

who comes to kiss me goodnight right about the time I start to work on the book each

night. They both make me smile and I just wanted them to know I appreciate their

patience, love and support.

—Scott Weiner

Acknowledgments

First, we would both like to thank the PRI gang; Alberto, Brad, Eric, Ethan, Glen, John,

Karen, Kerry, Nicole, Shrinand, and Tyler. Sometimes writing takes away from work and

we appreciate their dedication in our stead. Special thanks to Ethan for his LDAP

expertise and Alberto for listening to Stephen complain about another late night, a fouled

up example, or basically anything worth commiserating about.

And where would authors be without editors? Many thanks to Terri Hudson, Kathryn

Malm, and Gerrie Cho for transforming our sometimes confused expositions into logical

explanations.

Finally, unending thanks to our wives Cheryl and Susan. You can only apologize for

coming to bed at 3 a.m. and working through the weekend so many times before you

realize that the person you keep apologizing to knew long before you did what your

decision to write a book entailed. I know from my experience that Cheryl is always two or

more steps ahead of me, and although I kick myself for not figuring it out sooner, I

wouldn’t have it any other way. I bet if you asked Scott about Sue, he would tell you the

same thing.

Introduction

Overview

Java is steadily becoming the language of choice for new enterprise-wide development

projects. A number of factors have lead to this explosion in Java’s popularity as a

programming language and in particular as a language for large scale development

projects. If you are reading this book, we expect that you already have some familiarity

with Java as a programming language, and won’t bore you with the laundry list of

marketing buzz words that are often used to excite folks about Java. Instead, we have

focused this book on the enterprise technologies that Sun is standardizing for the Java

developers. These technologies, as standards, are motivating numerous companies to

move their new projects onto the Java platform.

Our goal for Developing Java Enterprise Applications is to provide developers and

evaluators alike an opportunity to learn about Java enterprise development at a

technology level and from the perspective of a real world project. There are a number of

emerging Java technologies and we have taken a snapshot of the available libraries,

frameworks, and tools. Certainly, the list of available technologies will grow, but this book

should serve as a solid foundation for your Java development.

Currently the main technologies being adopted, or about to be adopted, by enterprise

developers include JDBC for database connectivity, the Java Naming and Directory

Interface (JNDI) for accessing services, and RMI for Java remote method invocation and

distributed objects. On top of this foundation are Servlets, JavaServer Pages, Enterprise

Java Beans, Java Messaging Service, and Transaction Management. All of these

combine into a feature-rich tool kit for developing Java applications.

What about CORBA?

You may have noticed that in all this discussion, we have made no mention of one of the

more pervasive and potential influential technologies in enterprise development, CORBA.

In researching and writing this book, we realized that their just wasn’t room to do CORBA,

and the Java technologies for accessing it, justice. Seeing the number of books that just

discuss Java and CORBA, we decided that our time, and your money were better served

discussing the other technologies well and leaving CORBA for a separate manuscript. We
