Object equality in context of hibernate / webapp

Question

How do you handle object equality for java objects managed by hibernate? In the \'hibernate in action\' book they say that one should favor business keys over surrogate keys

Answer 1

Thanks for all your input. I decided to use surrogate keys and provide those right at object creation time. This way i stay clear of all that 'rarely' changing stuff and have something solid to base identity on. First tests look rather good.

thank you all for your time. Unfortunately, i can only accept one answer as solution i will take Pascals, as he provided me with good reading ;)

enjoy
