JPA (Java Persistence API) is a JCP Standard for Object-Relational Mapping (ORM) persistence for the Java platform, both JavaSE and JavaEE. This talk will discuss and show examples from the latest version of the spec: JPA v2.0. Based upon influences from a variety of technologies that competed with the original JavaEE EJB specification for Entity beans, JPA promotes the use of light-weight POJO-based Entity objects and a simple EntityManger interface to control the CRUD operations to the backend RDBMS. Even with the rise of NoSQL data stores, there are still many applications that are well suited to a relational database solution and JPA is my favorite ORM tool for Java development.
In the talk I will present:
* Entity Operations
* Query Language
* Containers & Deployment
* "In Practice" common problems, solutions and patterns of use
