The EJB architecture was the first component-based development model for Java EE specification. It consists of three main components; enterprise beans (EJBs), the EJB container, and the Java application server. In this course students will develop EJBs to run it run inside an EJB container, that is running on a Java EE compliant application server. Students will see that EJB Components enables you to build scalable and accessible enterprise applications

A Session Bean is the most generic type of enterprise bean, It representing a facet of business functionality that can be called by a client. in the same or different JVM via Local or Remote access respectively. This module will concentrate on the advantages of having the EJB model to build distributed applications and the role of the most common EJB, Stateless Session Beans, that can be pooled for remote clients or sit in the context of a Web Application.

In this module, state will be discussed via the use of Singleton and Stateful Session Beans scoped to a client conversation. It will then move onto Jakarta Persistence or Java Persistence Architecture (JPA) to cover how in a Java EE application we communicate with Databases.
