database identity (or surrogate key) for equals()

Hi,

I am thinking of using surrogate key (the one generated by

database) to implement equals() of domain object for ibatis.

Now is there any pitfall I need to know???

Anyone doing things this way??

Although 'Hibernate in Action' said this is a bad idea but

I only want to compare objects that have id so I guess

this shud be ok.

Thanks,

Sam
