"May the source be with you"
Don't know about such a doc, you will have to look at the source code itself. Not for the faint hearted, it is a complex beast and (unfortunately) has very little inline comments.
You have to look at the server module, package org.jboss.ejb.plugins.cmp
Do u know where exactly i find the src (so i don't need to decompile)?
I took a look at cvs at sourceforge but couldn't find the directory.
