Enterprise JavaBeans

The core composing components of an enterprise application in Jakarta EE are Enterprise JavaBeans. They are plain Java objects with embedded business logic, supported by different services from the business tier, such as remoting, transaction management, user session management, timer services, and more.

In this book, we'll learn what enterprise Java beans are, what are they used for, and what services they provide for your embedded business code. We'll study and practice the three available types of sessions bean: stateless, stateful, and singleton.
