The new 2.1 version of the Enterprise JavaBeans (EJB) spec extends its support for web services and the Java Web Services APIs, expands its asynchronous messaging support, adds XML Schema for deployment descriptors, and introduces a new Timer service, which allows for scheduling EJB jobs. The essential--and award winning--book on EJBs, Enterprise JavaBeans, has been completely revised and updated in this new fourth edition, to provide the real-world, nitty-gritty detail developers need to master EJB 2.1.Previous editions of this clear and engaging introduction to EJBs were voted the "Best Java Book" by the editors and readers of Java Developer's Journal, the "Best Java Book for Experts," by JavaPro editors, and one of the Top Computer Books by Amazon.com. The fourth edition lives up to--and surpasses--the excellent reputation earned by its predecessors.This authoritative and thorough guide includes everything that made previous editions the single must-have book for EJB developers: the authors solid grasp on the complexities of EJBs coupled with his succinct, easy-to-follow style; hundreds of clear, practical examples; adept coverage the key concepts EJBs ; and diagrams to illustrate the concepts presented. It also includes everything you need to get up to speed quickly on the changes wrought by EJB version 2.1, an architecture overview, information on resource management and primary services, design strategies, and XML deployment descriptors.In this edition, we're adding an EJB workbook for JBoss 4.0. The workbook shows how to deploy all of the examples on the JBoss 4.0 application server. It addresses an important problem with EJB: deploying the software on a server can be extremely difficult. JBoss is an open source project that has become the most widely used J2EE application server.Good technical authors may lay the facts before you, but great ones offer the distilled essence of their own experience and insight. Richard Monson-Haefel has provided just what Java developers need to know to harness the complexity of EJBs. What makes Monson-Haefel a master of technical authoring can be seen in his well-thought-out and logical progression of ideas, and in his examples practical, precise, usable examples, large enough to test key concepts but still small enough to be comprehensible taken apart and explained in the detail you need to deploy those principles in other situations.If you work with EJBs--or want to--this book will earn a favored spot on your bookshelf.

Thoroughly enhanced for the EJB 1.1 specification, Enterprise JavaBeans, 2nd Edition provides a great introduction to the world of server-side Java components. With plenty of material on EJB architecture and design, this new edition can serve as an authoritative resource for mastering today's bean standards.
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

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.
