Whether you're new to EJB and J2EE or you're upgrading from previous versions, this hands-on, practical book will teach you the real "nuts and bolts" of Enterprise JavaBeans 2.0 development. Unlike previous books, this one shows how to make the most of EJB 2.0 within the broader context of the entire J2EE 1.3 platform, helping you use the facilities available throughout the platform and use Enterprise JavaBeans to deliver on all the functionality the platform can offer. This book introduces every significant element of the recently finalized EJB 2.0 specification, using real-world examples you can adapt for your own projects. Every chapter ends with a hands-on project; the book ends by showing how to integrate these projects into one full-fledged enterprise application. Coverage includes packaging and deploying EJB 2.0 components, migrating existing EJB 1.0/1.1 applications to EJB 2.0 environments, and much more. For every Java developer working with J2EE technologies in enterprise environments -- including those new to EJB and J2EE as well as those migrating from EJB 1.0 or more
