This book simplifies the creation of well-designed enterprise applications using the upgraded Enterprise JavaBeans 2.0 specification. Experienced Java platform mentors Gail Anderson and Paul Anderson use detailed code examples to introduce every key skill involved in creating components, stand-alone Java platform clients, and JavaServer Pages API clients. They introduce powerful EJB platform design patterns, and show how to apply them in real-world projects while avoiding critical errors in application design. Using actual business components, the authors show how to make the most of these key EJB component architecture features: Stateless and stateful session beans Entity beans with bean-managed persistence Entity beans with container-managed persistence Container-managed relationships Local and remote interfaces The Enterprise JavaBeans Query Language EJB 2.0 specification message driven beansEach chapter includes a "Design Guidelines and Patterns" section designed to help you assess tradeoffs associated with your design decisions, and key point summaries that tie together important concepts. In short, Anderson and Anderson give you everything you need to build EJB 2.0 platform applications with maximum robustness, scalability, and performance.
