Besides a general introduction to EJBs, the new edition of this book excels at highlighting the differences between the EJB 1.0 and 1.1 standards. Sample code is provided for both versions. For deployment, EJB 1.1 now relies on XML to define all bean resources and dependencies. For every sample bean, the author provides the XML, as well as the old-style Java code for EJB 1.0. There's also plenty of coverage of the new reliance on JNDI (the Java directory service) in EJB 1.1 and other late-breaking Sun standards, such as combining EJBs with servlets and JSPs for delivering dynamic Web content.
This text is organized as a tutorial to the major types of EJBs with full coverage of entity beans (for accessing databases) and session beans (for managing "conversations" with particular clients). The author covers all the bases here with numerous diagrams describing the life cycle of beans and how they cooperate with today's application servers. As in the first edition, sample beans for a cruise ship booking application let you see actual EJB code in action. Helpful appendices list all EJB APIs and other useful information (such as a list of current EJB vendors).
In all, the revised edition of Enterprise JavaBeans shows off the considerable strengths of the new EJB 1.1 standard. Suitable for any working Java programmer or IT manager, the clear presentation of the strategies and techniques for successful component design help make this book a smart choice for successful development with EJBs. --Richard Dragan

From the Author
This book is has complete coverage of EJB 2.0. The book also covers EJB 1.1, for readers still using legacy servers.
Over three years have gone into refining the content this book to ensure that it was technically accurate and a pleasure to read. Delivering content that meets these standards isn't easy, and while my name is on the cover, credit is shared with many people.
In addition to this book, we are making companion workbooks available that show how to download, install, and configure different servers so that you can run the books examples on different EJB products. Workbooks and example code are available for free download from OReilly.com for WebLogic 6.1, WebSphere 4.0 and other products.
Thank you for considering my book, Enterprise JavaBeans, 3rd Edition, and good luck in your career as a distributed object professional. It's an exciting field with unlimited challenges and rewards.
