Hi :

I find that there is a session.persist() method in hibernate3 document. The doc says the persist is save an object to database. But what different between session.persist() and session.save() ? Thks

as far as I know, save() is also used when you wish to get an identifier for your newly created object. Also, note that cascade operations differ between save and persist (for persist, only the 'persist' cascade operator can be used).

So I think the "persist" method is not useful. But why hibernate have this method? Maybe it should be deleted from Hibernate API ?
