Developing Applications with Java Persistence API (JPA)

This 2-day instructor-led course teaches students how to build, develop, and run Java applications that use the Java Persistence API (JPA). Students use IBM Rational Application Developer V7.5, which provides complete support for the JPA specification, to develop the JPA-based applications in this course. JPA provides a mechanism for managing persistence and object-relational mapping. It represents a significant evolution over previous persistence techniques, such as Java Database Connectivity (JDBC) and EJB 2.0 Container-Managed Persistence (CMP), and it can be used in both Java Standard Edition (Java SE) and Java Enterprise Edition (Java EE) applications. This course begins with an overview of persistence and the JPA specification, including features of the Java Platform that support JPA and JPA architecture. Subsequent topics include creating JPA entities, using Java Persistence Query Language (JPQL) and performing object-to-relational mappings (ORM) for persistent data. Students also learn how the use of JPA in applications differs between the Java SE and Java EE environments. Hands-on exercises throughout this course give students practical experience developing JPA-based applications with IBM Rational Application Developer V7.5. JPA development skills covered in the exercises include creating entity classes, developing a Java SE application to perform database operations, mapping entities to single and multiple tables, and working with JQL queries. To learn how to use JPA entities running in an EJB container, students should attend one of the following courses:

• Developing EJB 3 Applications for WebSphere Application Server V7 (WD352)
• Developing EJB 3 Applications for WebSphere Application Server V7 (Remote Class) (VD352)
