Hi all,
I'm quite new to spring & hibernate and I get this error I've already said in the title of this post when trying to persist an object. Here are the mappings of the objects. Thank you all. If you need something else, just ask for it and I will post. I think is enough with the mapping files but I have no idea.
Hibernate version: 3.0

SdmValoraci
