Course duration: 2 Days

Overview

This course develops skills in using the Object/Relational Mapping tool Hibernate. The course uses the latest release version of Hibernate, 3.2, which is directly related to the new EJB 3.0 version defined in Java EE 5.0. By the end of the course, students will be prepared to set-up and use Hibernate as the persistence mechanism in Java applications.

Layout

The training course combines lectures with practical exercises that help the delegates to put what they have learned on the training course into practice. The exercises specifically build on what has been recently taught and are built up as the training course progresses.
