Presentation: Linda DeMichiel on EJB 3 & JPA

In this talk from last year's QCon London, Linda DeMichiel, who has been leading the EJB spec since the 1.0 days, presents EJB3, with a focus on JPA. JPA is a standard API for Java persistence and object/relational mapping that supports use in both Java EE and Java SE environments.  The talk covers key aspects of the Java Persistence API and its role in the development of EJB 3.0 apps, including use of the EntityManager API, persistence units and persistence contexts, queries, object/relational mapping, and how the combination of EJB 3 and Java Persistence facilitates the development of Java EE applications.
