Title

Managed JPA in an OSGi framework - getting the best of both worlds

Overview

The OSGi Alliance Enterprise Specifications release provides definitions and guidance for building enterprise technologies, such as Servlet containers, Object Relational Mapping frameworks, and JTA transaction managers, that can be used in an OSGi framework. This talk will describe benefits and limitations of the Java ^TM Persistence API (JPA) service defined by the OSGi Alliance Enterprise 4.2 release. Drawing on examples from the Apache Aries project, the talk will also demonstrate how a container implementer can build upon the existing specifications to provide managed JPA in an OSGi environment. Finally the talk will show how an OSGi JPA container can be integrated with the OSGi blueprint service to provide dependency injection, and a familiar programming model for JEE developers.
This session is intended for existing JEE and OSGi developers with an interest in learning more about how existing JEE technologies can be integrated and used in an OSGi environment.
