i'm quite new in the EJB-world. I've read EJB in Action to find an introduction in the whole topic. I think that I've understood a lot of the the concepts, but there are also some gaps which I want to close. For that I've started to sumarize some basic classes and to describe their purpose on one Din-A4-Sheet.
Perhaps someone else is interested in this, or find some errors. Any feedback about it is welcome.
