Firm JavaBeans 3.0 (EJB 3.0) is an important portion of Sun’s new light-weight Java firm version five platform (Java EE 5). they're used for the advance and deployment of component-based firm enterprise purposes similar to transaction-based purposes. Ever in view that its first unlock, EJB has been the topic of a lot media awareness and no little controversy. EJBs symbolize a cosmopolitan and strong expertise and EJB-based functions can aid excessive numbers of transactions and clients, with greatest safeguard. even though, earlier incarnations of EJB have end up appeared via many as a very advanced expertise which may bring about expensive and time-consuming suggestions which are tough to construct, enforce and keep. the recent light-weight EJB three is determined to alter all that. It has made large advances in ease of improvement, and its greatly simplified programming version has been greatly acclaimed and embraced. starting EJB three takes the reader during the information of the EJB 3.0 structure, and indicates how EJB can be utilized to advance strong, standards-based backend enterprise good judgment. With 12 years of mixed EJB adventure, the authors supply many useful insights into the whole EJB structure, masking all parts of the EJB 3.0 specification, together with its new endurance framework, simplified improvement version, and different key new gains.

Listing 2-2. Remote; @Remote public interface SearchFacade { List wineSearch(String wineType); } Listing 2-3 shows the code snippet for the SearchFacade local business interface, with an @Local annotation and a wineSearch() method declaration. Listing 2-3. Local; @Local public interface SearchFacadeLocal { List wineSearch(String wineType); } Business Methods The methods implemented in the bean class must correspond to the business methods declared in the remote or local business interfaces. They are matched up based on the convention that they have the same name and method signature.

Recognizing that a combined 800 pages of reference material can be daunting, we provide an on-ramp for developers, unfolding EJB 3 one section at a time, and giving you the information and code examples you need to roll up your sleeves and get to work. As each chapter unfolds, you will not only learn about a new area of the spec, but you will learn through specific examples how to apply it to your own applications. Many of these samples come directly from the comprehensive, end-to-end, Java EE Enterprise Wines Online application covered in Chapters 7 and 12, so you can see how they fit into a bigger picture.

Much behavior is attached automatically to an EJB or entity without it being declared explicitly, such as the transactional behavior of session bean methods, and the names of the table and columns that persist an entity and its public properties. An annotation, or its counterpart in XML, needs to be explicitly specified only when nondefault behavior is desired. In the most common cases, in which default behavior is desired, this practice leads to very sparse, clean code. This development model is known as configuration by exception, because only in exceptional (non-default) cases is it necessary to explicitly configure the behavior of the bean.
