RE: [jBoss-User] Quick questions about EJB in general

[Hardy, Patrick, DDI - Garden City]

Thanks Rickard. I was thinking in terms of EJB 1.1. That's why I was a bit
confused.

As I understand it, JBoss complies with the EJB 2.0 standard now except for
the persistence manager. However, what I would like to know is when will the
EJB 2.0 spec. become official or "blessed" by Sun? Does anyone know, or has
it already been blessed?

Thanks.

Pat

Better yet, I wrote it :-)

The EJBDoclet allow you to use the EJB 2.0 CMP style, which means that
the bean provider writes abstract EntityBeans, with abstract get/set
methods for all persistent fields. EJBDoclet then generates a concrete
subclass which is EJB 1.1 compliant, which is thus deployable in an EJB
container.

If you have any further Q's on EJBDoclet, please use the EJBDoclet
mailing list at sourceforge.net/projects/ejbdoclet.

regards,
  Rickard

ps. BTW, you got it backwards: YOU create an abstract class, and
EJBDoclet creates a concrete subclass of it.
