I have the following model :


class hibernateobject {
.....
}

class businessobject extends hibernateobject {
.....
}

class businessobjectSpecific extends businessobject {
.....
}


For the 3 classes, I need the 3 same mappings files (except for the class name, i set polymorphism=explicit).
I can't use the subclass clause because I don't have a discriminator and for our application we need the 3 classes.

Is there any way to specify the mapping or how can i tell to hibernate to use the same persister for the 3 classes ?

What about the performance issue by multiplying by 3 the numbers of mapping files (except at the start of Hibernate) ?

I specify one mapping file (the Hibernate Object one) and I modify the methods getPersister in SessionfactoryImpl (loop -> getSubclass). This work perfectly for session.save, session.load, but this solution is too ugly (Performance ?, specific hibernate version....)

Thanks,

Will you ever be persisting a hibernateobject, or a businessobject? In this case usually only the businessobjectSpecific is the one that is persisted. The rest are the results of a good class diagram.

If this is not the case then I would recomend using the default discriminator.
