This course offers a comprehensive and detail-oriented treatment of the Java Persistence API (JPA) and its use in the Java-EE environment. We cover JPA basics including simple object/relational concepts and annotations, persistence contexts and entity managers, and configuration via persistence.xml. We get a good grounding in the Java Persistence Query Language (JPQL) and take advantage of a prepared JPQL query console to explore the two schemas on which the course's case studies are based. We then look at practical issues involved in using JPA in the enterprise context, including Java EE Bean Validation, working with server-managed data sources, dependency injection, container-managed transactions, and transaction propagation.
This version of the course supports JPA 2.1 with a choice of two providers: EclipseLink 2.6, which is pre-configured for course exercises, and Hibernate® 5.0. Switching providers is just a matter of moving a few lines in and out of XML comments in the relevant persistence.xml file, and we encourage instructors to demonstrate both providers, to illustrate portability and for comparison of some finer points.
The course also supports either the Derby or Oracle® RDBMS. Derby is bundled with the course software and is pre-configured; a script is included to change over to Oracle configurations for all exercises and schema-creation scripts are available for both.
Each student in our Live Online and our Onsite classes receives a comprehensive set of materials, including course notes and all the class examples.
