The Enterprise JavaBeans Component

An Enterprise JavaBean is a component with a well-defined interface. This interface is defined by the EJB specifications. Enterprise JavaBeans are contained, executed, and managed within an EJB container. Any server that can host an EJB container and provide it with the necessary services can be an EJB server. This EJB component is either an implementation of an interface or extends an EJB class. This component is simply a Java class, written by an EJB developer, which implements the desired business logic and persistence.
