Which is why most of the time it just makes sense to update the values that
are supplied.

I appricate for ur suggestion, thanks a lot.
but
This type of approach will use only if a form have one or two parameters ,
but if ofrm have more than 20 parameters and like that there 20 to 30 forms
then, it will become redendunt to write such check mehtods for every form
parameters.
so Please can any one provide me better approach.
Thanks

Normally, it's just easiest to update all the values and if they haven't
changed, no harm, no foul. But if you need to, you can put a check in the
parameter mutators of the action. Something like:
private Bean bean;
public void setName (String name) {
if(!name.equals(bean.getName())) {
bean.setModified(true);
}
}
