Questions tagged [ejb-3.1]

This tag is used for question related to the session bean and message-driven bean component types of the EJB 3.1 programming model.

JSR 318: Enterprise JavaBeans, Version 3.1

Enterprise JavaBeans is an architecture for the development and deployment of component-based business applications. Applications written using the Enterprise JavaBeans architecture are scalable, transactional, and multi-user secure.

The Enterprise JavaBeans 3.0 specification focused on bringing ease-of-use to the EJB API. The purpose of the Enterprise JavaBeans 3.1 specification is to further simplify the EJB architecture by reducing its complexity from the developer's point of view, while also adding new functionality in response to the needs of the community.

The focus will be on the core session bean and message-driven bean component models and their client API. Although the Java Persistence API was developed within EJB 3.0, it will evolve under a separate JSR rather than within EJB 3.1.
