Software and versions This book covers Enterprise JavaBeans version 2.0 and version 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 to develop 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; you should be familiar with that server's specific installation, deployment, and runtime management procedures to work with the examples This book covers both ejb 2.0 and ejb 1.1. These two versions have a lot in common, but when they differ, chapters, or text with in a chapter, that specific to each version is clearly marked. Feel free to skip version-specific sections that de not concern you. Unless indicated, the source code in this book has been written or 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 Example Workbooks Although EJB applications themselves are portable, the manor in which you install and run EJB products vary wildly from one vendor to the next. For this reason its nearly impossible to cover all the ejb products available, so we have chosen a radical but very effective way to address these differences To help you deploy the book examples in different EJB products, the author will publish several free workbooks"which are used along with this book to run the examples on specific commercial and non-commerc servers. The workbook for a specific product will address that products most advanced server. So for example, if the vendor supports EJB 2.0, then the examples in the workbook will address EJB 2.0 features. If, on the other hand, the vendor only supports EJ then the examples in the workbook will be specific to EJB 1.1 Although there are plans to publish workbooks for as many different EJB server, at least two workbooks will be made available immediately. These workbooks free on-line in PDF format. The workbooks are all available at http://www.oreilly.com/catalog/entjbeans3/orhttp:/www.monson-haefel.com Copyright(c)2001 OReilly Associates 6DRAFT, 10/21/017/6/2001 Copyright (c) 2001 O'Reilly & Associates 6 Software and Versions This book covers Enterprise JavaBeans version 2.0 and version 1.1, including all optional features.
