Sun has posted the proposed final draft of JSR-318 Enterprise JavaBeans 3.1. New features in 3.1 include:
- A simplified Local view that provides Session Bean access without a separate Local Business interface.
- Packaging and deployment of EJB components directly in a .war without an ejb-jar.
- An embeddable API for executing EJB components within a Java SE environment.
- A Singleton session bean component that provides easy access to shared state, as well as application startup/shutdown callbacks.
- Automatically created EJB Timers.
- Calendar based EJB Timer expressions.
- Asynchronous session bean invocations.
Comments are due by November 3.
