EJB 3 is meant to recast Java server-side development into a mold you might not expect. Most server-side Java books tend to be serious affairs—heavy on theory, slightly preachy, and geared toward the advanced developer.
The tone is intended to be friendly, conversational, and informal. We made a conscious effort to drive the chapter content with examples that are close to the real-world problems you deal with every day. In most cases, we introduce a problem that needs to be solved, show you the code to solve it using EJB 3, and explore features of the technology using the code.
We cover theory when it is necessary. The goal of this book is to help you learn EJB 3 quickly and effectively, not to be a comprehensive reference book.
Instead, we provide deep coverage of the most useful EJB 3 features and its related technologies. We discuss various options so you can make educated choices, warn you about common pitfalls, and tell you about battle-hardened best practices.
