You will learn about the core concepts regarding EJB including why they are important, differences between stateless and stateful sessions, the Java Persistence API, and the JPA Entity Lifecycle using Eclipse. You will also look at the Java Persistence Query Language (JPA QL) and entity relationships.

Each LearnNowOnline training course is made up of Modules (typically an hour in length). Within each module there are Topics (typically 15-30 minutes each) and Subtopics (typically 2-5 minutes each). There is a Post Exam for each Module that must be passed with a score of 70% or higher to successfully and fully complete the course.

Prerequisites

This course is intended for intermediate to advanced Java programmers. System architects will find the advanced concepts especially beneficial in designing a framework.
