"Expresso Framework is supposed to have a J2EE mapping / integration. With this 
extra piece of software I think that you can program with Expresso's own 
`DBObjects', and these will automatically to EntityBean. A `DBObject' is 
theoretical a heavy duty Data Transfer Hashmap object and so can be mapped to 
any reasonable database table and therefore EntityBean."

In the original email that I wrote I thought there was an extra Expresso
Plugin available, which allowed Expresso to talk to EJBs on J2EE application
server directly. So you have to ask Sandra directly.

I was speculating in the last sentence about how you can deduce by
inspection that a DBObject is a glorified hash map.  I was skipping a lot
of steps in a way for Expresso to talk directly to an Entity Java Beans.
