The Apache OpenEJB community has released OpenEJB 3.0 final. OpenEJB 3.0 is an embeddable, lightweight EJB 3.0 implementation that can be used not only as a standalone server, but as an embedded server in Tomcat, JUnit, Eclipse, Intellij, Maven, Ant, or any other IDE or application. In addition to the features you'd expect in an EJB 3.0 implementation, OpenEJB emphasizes ease-of-use, painless configuration, and powerful testing possibilities so you can focus on product development.

As a daily user of OpenEJB 3.0, I've been thoroughly impressed by the quality of the product and by the assistance of the developers throughout the beta phases since last summer, and can say with perfect confidence that without OpenEJB 3.0 I would not be able to do the work I'm doing with EJB3. In particular, the ability to load OpenEJB directly into my testing harness increased my development speed by an order of magnitude, because I can run tests with real EJBs against a real database in memory, and when the test finishes the database gets discarded. That means no loading tomcat, no expensive packaging of components, no rebooting servers, no delays. I've wanted to do this kind of development for years, and now it's a reality.
