This new series was designed for the software developer who -- whether to prepare for an interview or a new project -- needs to come up to speed quickly on a new language or technology. CodeNotes presents the most succinct, accurate, and speedy way to ramp up. Most programming books give equal weight to all areas of a given technology. CodeNotes, by contrast, drills down to the core aspects, focusing on the key elements needed to quickly understand -- and immediately implement -- a technology. CodeNotes was conceived and written by a team of seasoned, published software developers. The series offers a fresh approach, providing easy-to-follow labs that use real-life case studies, exercises, and "skeleton code" to help demonstrate the key concepts. It is also the first series to offer, at its launch, a distinct and highly effective electronic component, which includes an e-book edition and access to a Web-based developer community where CodeNotes readers can communicate with both the authors and other developers and take free on-line tests to gauge their understanding. This CodeNotes edition will introduce the Java developer to the key technologies of J2EE 2. Enterprise Java Beans, Java Server Pages, and Java Servletes will be covered individually, and architectural examples will be provided of how these technologies can work together. Popular application servers such as BEA Web-logic and IBM WebSphere will also be introduced.
