EJB 3.0 officially announced (from Cedric's weblog)

* POJO-based (no more abstract methods, support of new)
* Simplification of the design (now optional: homes, component interfaces, lifecycle methods, no more EJBLocalObject, etc...)
* Use of injection to make it easier to test outside the container
* Use JSR 175 annotations instead of deployment descriptors
* Support for disconnected access
* Many EJB QL enhancements (bulk updates, etc...) as well as support for native SQL
* A standard O-R mapping

disconnected accessとはData transfer objectが不要になるということでしょうか。
