Hi Simone,
Normally the ORM takes care of creating the database schema on the basis of the annotations. The annotations look fine
to me.
Which ORM are you using?

Hey Simone,
My question is more what JPA solution you use, hibernate or eclipselink or something else?
Also, you say that no FK's are generated, did you check in the database itself for this?
(I ask because on the basis of the annotation you showed the FK should be generated by the ORM layer)
