J2EE™ Tutorial, The

Chapter 5. Bean-Managed Persistence Examples

Dale Green

Data is at the heart of most business applications. In J2EE applications, entity beans represent the business objects that are stored in a database. For entity beans with bean-managed persistence, you must write the code for the database access calls. Although writing this code is an additional responsibility, you will have more control over how the entity bean accesses a database.

This chapter discusses the coding techniques for entity beans with bean-managed persistence. For conceptual information on entity beans, please see What Is an Entity Bean? (page 51).
