Getting Started with the Java Persistence API, Java EE 5, Self-Study Course

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 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.
