Thank you Piero, I see your point, I am not thinking on changing the database at the middle of the development process, at least, it isn't my priority.
Anyway, I am thinking on developing some business components, as tapestry modules, which should interact with the underlying database, but I don't want to couple them with neither hibernate nor anyone database technology, so, I am thinking which is the most standard way to make it abstract.
