Hi! I'm using EjbDoclet and thinks it's very good (thanks Rickard!). Look below on my

Required by the spec is the home, remote, PK (when EB) and bean class AND the
ejb-jar.xml file. Rest is good-to-have classes :) The generated bulk data class i
guess is not to difficult to understand what to do with. Use it when sending entity
data back and forth between ejbs and between client and ejb. The usage of the
generated CMP/BMP class may seem more unclear at first but i think that it is good to
seperate out all the methods (or most of them) that has with persistent to do, and
only keep the real buisiness methods left in the bean class which now is really slim.
And as a feature you can easily switch your bean between beeing a CMP or a BMP bean.
I guess Rickard Öberg has more arguments :-)
