These are known as Dependent Value Classes (DVC). which JBoss supports.  the
only requirement is that whatever you put into the Map must be serializable.
Read the J2EE 1.3 spec on DVC and Get hold of the for pay CMP doc for JBoss
where there is some info on it.  It should be possible, although I've never
worked with DVC.
