Just a (maybe stupid) question : what's the interest of using EJB if you
already have Corba ? Apparently, i see a disadvantage in the fact your methods
return objets keys, rather than object themselves. Can't you use another Corba
object to browse your hierarchy, whose methods would return objects directly ?
