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.

Subject: Check database before INSERT in iBatis




Hi,

I have customer registration web application. Where it takes 3 pages to complete the process before submit. Once customer is registered, i.e. the records are inserted into 3 different tables then user can edit the registration.

Right now, I have a code that retrieves the record from each table and store it into Value Object class (model) and keep that into session until I update the records at the end of 3 pages. I update the record only if any value is different from VO to new ActionForm being edited else not updating.

Is there any shorter way of doing this task in iBatis?

Thanks
Jasmin
