This book covers Enterprise JavaBeans Versions 2.0 and 1.1, including all optional features. It uses Java language features from the Java 1.2 platform and JDBC. Because the focus of this book is on developing vendor-independent Enterprise JavaBeans components and solutions, I have stayed away from proprietary extensions and vendor-dependent idioms. Any EJB-compliant server can be used with this book, but you should be familiar with your server’s specific installation, deployment, and runtime-management procedures to work with the examples.
EJB 2.0 and 1.1 have a lot in common, but when they differ, chapters or sections within a chapter that are specific to each version are clearly marked. Feel free to skip version-specific sections that do not concern you. Unless indicated, the source code in this book has been written for both EJB 2.0 and 1.1.
Examples developed in this book are available from ftp://ftp.oreilly.com/pub/examples/java/ejb/. The examples are organized by chapter.
