Hi David,
let's continue this in a new thread, as it might not be related to the original question.
Actually, I don't get the problem ;-). So you have autogenerated classes, which contain no annotations, but you want to let the server detect them as EJBs?
I think a hibernate property will not help, you need to do an EJB way. If annotations are not possible, declare them in ejb-jar.xml.
Hope this helps
Wolfgang
