Re: hibernate and field symbolic name

Raoul,

currently I'm working on an update for svc-persist-hibernate... mainly
to keep it in sync with hibernate 3.0; but internally the service
changed (almost) completely. I hope to get it done by tonight, but right
now I have to take a coffee in a bar ;-) , because I'm struggling for
some hours with the programmatical configuration of hibernate
(org.hibernate.mapping especially). I cleaned up a lot, so I hope that
things are easier to understand (especially the variaous hibernate
parameters that you can pass to fields).

Cheers,

Aleks
