EJB 3 in Action (April, 2007), Debu Panda, Reza Rahman, Derek Lane | Книги

EJB 2 is widely used but it comes at a cost—procedural, redundant code. EJB 3 is a different animal. By adopting a POJO programming model and Java 5 annotations, it dramatically simplifies enterprise development. A cool new feature, its Java Persistence API, creates a standard for object-relational mapping. You can use it for any Java application, whether inside or outside the EJB container. With EJB 3 you will create true object-oriented applications that are easy to write, maintain and extend.
