 Linda  DeMichiel, Chief Architect: EJB spec

Linda DeMichiel is a senior architect in the Java EE Platform group at Sun Microsystems and the chief architect for Enterprise JavaBeans 3.0 and the Java Persistence API. As the Specification Lead for JSR-220, she was responsible for launching and leading the initiatives for Enterprise JavaBeans 3.0 and the Java Persistence API under the Java Community Prcoess.

She has over 20 years of experience in the areas of databases, object persistence, distributed computing, and OO in both industry and research. Before assuming responsibility for EJB, she led the team that implemented Sun's first object/relational persistence product, and worked earlier at IBM on object/relational extensions to both DB2 and the SQL99 standard. She holds a Ph.D. in Computer Science from Stanford University.

Presentation: "Java Persistence and EJB 3"

Track:   Java in Action

Time: Wednesday 17:15 - 18:15

Location: Elizabeth Windsor


Enterprise JavaBeans 3.0 and the Java Persistence API are two of the major technologies of the new Java EE 5 Platform.

With the EJB 3.0 release, the EJB architecture has undergone a dramatic simplification targeted at ease of use for application developers.

One of the most significant results of the work on EJB 3.0, however, has been the introduction of a new, standard API for Java persistence and object/relational mapping that supports use in both Java EE and Java SE environments.

This talk will cover key aspects of the Java Persistence API and its role in the development of EJB 3.0 applications, 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.

We'll conclude with a discussion of work in progress on the next releases of EJB and Java Persistence within Java EE 6---where we are going and where we need to go.

Presentation: "EJB/JPA feedback with the expert group BOF"

Track:   Solution Track 2

Time: Thursday 13:00 - 14:00

Location: Wordsworth Room


The initial version of the Java Persistence API (JPA) was released last year at JavaOne, along with the Java EE 5 specification. Since that time, it has gained significant traction among developers, and all the major object/relational mapping implementations have embraced the new specification. Now that we've gotten the release out, implementations online, and built some real-world experience, it's time to start looking towards the next version of the JPA specification.

Come to this session to hear what new features members of the EJB expert group team are thinking about, and to provide feedback of your own into the future of the JPA specification.
