Course Summary

Home > Courses >Back-End Development Training >Java >Introduction to EJB3

The Introduction to EJB3 training course is designed to demonstrate a code-level overview of the three key Enterprise Java Beans (EJB3) technologies: Session Beans, Entity Beans, and Message-Driven Beans.

The course begins with a review of distributed programming concepts. It then examines reusable business logic with Session Beans, persistence with Entity Beans {also known as Java Persistence Architecture (JPA) Entities}, and workflow logic using Message Driven Beans. The course concludes with a discussion about using EJBs as web service endpoints, implementing transaction policies, and configuring EJB security.
