Overview of this book

This book is a fast-paced tutorial that explores the key features of EJB 3 with many accompanying examples. This book is not a complete reference guide, but a concise exploration of EJB 3's core elements. This book is primarily aimed at professional developers who already have a working knowledge of Java. Enterprise architects and designers with a background in Java would also find this book of use. Previous experience of working with Java is essential and knowledge of relational databases is desirable. As this book is an introduction to EJB 3, it is aimed at those who are new to EJB 3. As the new version of EJB is so radically different from the previous version (EJB 2.x), the book is suitable for and should be of interest to those who have had experience working with EJB 2.x. The text makes it clear where the differences between the versions of EJB lie, although they are not explored in detail.

Summary


We have covered a lot of ground in this chapter. We have seen that session beans are an EJB technology for encapsulating business logic. Session beans can be either stateless or stateful. We had our first examples of using metadata annotations in our beans. We looked at packaging and deploying session beans using Ant scripts. We showed how a client running outside an EJB container would invoke a session bean using JNDI. We also showed how a client running in an Application Client Container can use dependency injection instead of JNDI to invoke a session bean.

We described the lifecycle for both stateless and stateful session beans and looked at examples of session bean lifecycle callback methods
