New Alpha release of WAS 6.1 Feature Pack for EJB 3.0
I couldn't resist posting this announcement, even though I'm on vacation this week and with limited net availability.
The EJB3 Feature Pack alpha release contains a preliminary implementation of the Enterprise JavaBeans 3.0 (EJB3) specification.
EJB 3.0 introduces major simplifications and ease-of-development improvements to the EJB programming model and the persistence model. These changes are designed specifically to reduce the complexity of EJB programming, through adherence to the following principles:
Plain Old Java Object (POJO)-based development for both Business Logic and Persistence
No dependencies on external framework interfaces (for example javax.ejb.)
Allows unit test outside the app server
Highly leverage defaults -- Only need specify an item if you do not want the default
Highly leverage J2SE 1.5 annotations -- Annotations may be used stand-alone or in combination with XML descriptors
Persistent data objects matching the persistence domain model -- Full support for inheritance and polymorphism
The EJB3 Feature Pack alpha does not provide a full implementation of EJB3 yet. However, there is enough implemented to build basic applications that drive business logic and persistence. The Getting Started Guide (available from the "Library" tab, from below's code download link) describes current limitations and scenarios that should be possible with this release.
