Description:
Written for the experienced Java developer or manager, Professional EJB provides a truly in-depth guide to using Enterprise JavaBeans, including versions 1.0 and 2.0. Filled with practical advice for good design and performance and plenty of useful sample code, this title is one of the best available guides to working with this powerful component standard.While some titles on EJB are long on theory and short on the nuts and bolts of actually deploying and running beans on real platforms, this book distinguishes itself with plenty of practical code as well as the XML descriptors needed to deploy each sample. (With EJB the genius is in the details--more so than with most programming topics--and the authors supply the necessary deployment specifics here.) Weighing in at over 1,200 pages, this text is massive but exceptionally well paced. The Wrox team of authors have assembled a simply excellent tutorial for building and using EJB, beginning with the version 1.0 standard. The authors start with session and then entity beans, exploring features built in to today's J2EE-compliant application servers. Coverage of the EJB 2.0 standard, along with new topics like messaging beans and the Java Message Service (JMS) comes later. Besides actual source code and an excellent case study for an online movie ticket booking application, several chapters explore design issues with EJB in detail. At this point in the book, there is an excellent section on a half-dozen reusable EJB design patterns. There's also plenty of advice for squeezing more performance and scalability out of today's J2EE application servers. Later chapters turn toward newer technologies like wireless and Web services, and how to integrate EJB with two older distributing computing standards (COM and CORBA). There's coverage on installing and running some of today's most popular J2EE application servers, from BEA WebLogic, to IBM WebSphere Application Server, to the free, open-source JBoss alternative. (In theory, any properly designed EJB will run on any server, but it helps to get some help with each J2EE application server platform.) Overall, the focus on running EJB in real application servers helps makes this book a success. Professional EJB will be a good refresher for those making the transition to EJB 2.0, as well as those developers who are new to Sun's powerful component standard and want to get it right in a hurry. --Richard Dragan
