If you override equals, you have to have two VO objects to do the
comparison.
I think it is better to perform this type of work in one of your
business or service methods. You could then let your user know if
anything was updated.

No I think. iBatis is not aware whether your VO-s have changed and
can not decide whther to run updates or not.
Why don't you override the Object.hashcode() method on your
VO and call it and save the value when you retrieve the
record. Call it again when the user submits their changes.
If the values are different, the a change was made.
Hm, I usually override equals. Any advantages with hashCode?
But most of the time (being lazy) I execute updates without checking
if there were atual changes. You know modern hardware and database
software are so fast.
