Summary
The EJB architecture simplifies enterprise applications by basing them on standardized, modular, reusable components. The EJB architecture provides a complete set of services to those components, and handles many details of application behavior automatically. By automating many of the time-consuming and difficult tasks of application development, J2EE technology enables enterprise developers to focus on adding value, which enhances business logic, rather than building infrastructure.
