The Java Persistence API (JPA) of the Java Community Process is a standard for the object-relational mapping (ORM) of Java objects. JPA can be integrated into both Java EE applications with EJB3 and/or Spring as well as into any Java SE applications. As a result, it is possible to implement persistent objects with standardized interfaces portably. The open source project Hibernate was already widely used before the adoption of JPA and has made a name for itself as a very good OR mapping framework. It fully supports the JPA specification and adds useful non-standard features. Using practical examples and exercises, the participant will learn how to work with the Java Persistence API using Hibernate. Looking at the wider market reveals other JPA providers such as EclipseLink and OpenJPA.
