Beginning Ejb 3: From Novice to Professional (Beginning: From Novice to Professional)

Enterprise JavaBeans 3.0 (EJB 3.0) is a vital component of Sun's new lightweight Java Enterprise Edition 5 platform (Java EE 5). They are used for the development and deployment of component-based enterprise business applications such as transaction-based applications.

Ever since its first release, EJB has been the subject of much media attention and no little controversy. EJBs represent a sophisticated and powerful technology and EJB-based applications can support high numbers of transactions and users, with maximum security. However, previous incarnations of EJB have come to be regarded by many as an overly complex technology that can lead to costly and time-consuming solutions that are difficult to build, implement and maintain.

The new lightweight EJB 3 is set to change all that. It has made huge advances in ease of development, and its drastically simplified programming model has been widely acclaimed and embraced. Beginning EJB 3 takes the reader through the details of the EJB 3.0 architecture, and shows how EJB can be used to develop powerful, standards-based backend business logic.
With 12 years of combined EJB experience, the authors offer many practical insights into the entire EJB architecture, covering all areas of the EJB 3.0 specification, including its new persistence framework, simplified development model, and other key new features.

The recently-released Enterprise Java Beans 3 improves upon the old EJB architecture by reducing its complexity from the developer's point of view. Aimed at beginning to intermediate programmers, this text uses numerous examples to introduce the main components of the EJB 3 API. Coverage includes (for example) session beans, entities, persistence features, message-driven beans, and Web services. The migration of applications from EJB 2.x to EJB 3 is also addressed.
