Stateful Session EJB Part 3 Stateful Class

Enterprise JavaBeans ('EJB') is a managed, server-side component architecture for modular construction of enterprise applications. The EJB specification is one of several Java APIs in the Java EE specification. EJB is a server-side model that encapsulates the business logic of an application. A session bean encapsulates business logic that can be invoked programmatically by a client over local, remote, or web service client views. Session beans are of three types: stateful, stateless, and singleton. Stateful Session Beans The state of an object consists of the values of its instance variables. In a stateful session bean, the instance variables represent the state of a unique client/bean session. Because the client interacts (“talks”) with its bean, this state is often called the conversational state. Session bean is similar to an interactive session. A session bean is not shared; it can have only one client. When the client terminates, its session bean appears to terminate and is no longer associated with the client.
