Expanding slightly on the reply and trying to cover this part of the
original question...
>> And how do I know which one to use?
The EJB implementation is almost always bounded to the Java EE (nee
J2EE) implementation. Unlike Java Persistence, there is not much
plugability and even the Specification Compatibility Tests are
integrated within the platform. To my knowledge, the only 2 EJB 3.0
implementations that are "final" right now are GlassFish and TmaxSoft;
both JBoss and Oracle have betas but they will not become final until
when they have a complete Java EE 5 App Server.
So, in practice, you choose the EJB implementation at the same time as
you choose your container.
We, obviously, believe Project GlassFish is delivering the best Java EE
5 AppServer and would encourage you to use it...
