Overview

The Getting Started with Java Persistence API course provides students new to Enterprise JavaBeans (EJB) 3.0 and the Java Persistence API (JPA) with a step-by-step guide for creating an application with these technologies. Using JPA and NetBeans, students build an enterprise application that performs all the standard database operations: create, retrieve, update, and delete (CRUD). In addition, students will refactor their code.
