Overview

The Getting Started with Java(TM) Persistence API course provides students new to Enterprise JavaBeans(TM) (EJB(TM)) 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(TM), students build an enterprise application that performs all the standard database operations: create, retrieve, update, and delete (CRUD). In addition, students refactor their code to include 1-to-1 and 1-to-many relationships. Students are guided through the creation of the application and complete key portions of the application through hands-on labs.
