EJB 3.0 has simplified the programming model for Enterprise JavaBeans (EJBs) dramatically and introduced a new Java Persistance specification. In this new edition, we've updated Enterprise JavaBeans to deliver the latest need-to-know Java technologiesto you in the same award-winning fashion that drove the success of four previous strong-selling editions (over 150,000 copies in print).The book's fifth edition has been drastically overhauled for the latest specification of the Java programming language and provides everything you need to work with the eminent 3.0 standard. The authors' solid grasp on the complexities of EJBs coupled with a succinct, easy-to-follow style and hundreds of clear, practical examples are the reason this book was voted "Best Java Book" by the editors and readers of Java Developer's Journal.
If you're up on the latest Java technologies, then you know that Enterprise JavaBeans (EJB) 3.0 is the hottest news in Java this year. In fact, EJB 3.0 is being hailed as the new standard of server-side business logic programming. And O'Reilly's award-winning book on EJB has been refreshed just in time to capitalize on the technology's latest rise in popularity.
This fifth edition, written by Bill Burke and Richard Monson-Haefel, has been updated to capture the very latest need-to-know Java technologies in the same award-winning fashion that drove the success of the previous four strong-selling editions. Bill Burke, Chief Architect at JBoss, Inc., represents the company on the EJB 3.0 and Java EE 5 specification committees. Richard Monson-Haefel is one of the world's leading experts on Enterprise Java.
Enterprise JavaBeans 3.0, 5th Edition is organized into two parts: the technical manuscript followed by the JBoss workbook. The technical manuscript explains what EJB is, how it works, and when to use it. The JBoss workbook provides step-by-step instructions for installing, configuring, and running the examples from the manuscript on the JBoss 4.0 Application Server.
Although EJB makes application development much simpler, it's still a complex and ambitious technology that requires a great deal of time to study and master. But now, thanks to Enterprise JavaBeans 3.0, 5th Edition, you can overcome the complexities of EJBs and learn from hundreds of practical examples that are large
enough to test key concepts but small enough to be taken apart and explained in the detail that you need. Now you can harness the complexity of EJB with just a single resource by your side.
