Have heard of generating the byte code directly but never done it my self
before. My only concern is in that way will the debuging become
nightmare. (as we are not good @ reading byte codes as computers.)
plus there would be quite bit of code changing in the generation code..
but that is not impossible if it worth it.
Thanks

Thanks :) .. I read bit about cglib and saw the jar inside the geronimo
as well. With the help of tools ect and with above approch I belive it is
much better than I thought at first.

yes it would make the deployment simpler .. plus I think we shoud ask what
the dims think about it as well.
Thanks

Normally, you write the standard code reused across all beans in normal
java code that you compile an pack in a library jar. Then you only
generate a tiny bit of byte code to implement an interface and call
your library java code. This is how we implement EJB. We generate an
implementation of the EJB interfaces and all that implementations does
is call our EJB library code, which does stuff like check permissions
and start transactions.
Anyway, it is not important for now, but something I'd like to do in
the future.
