I would like to be able to perform a "dirty" check on my entity, to avoid saving the object if it hasn't been modified. Does Hibernate offer any native facility to perform a "dirty" check?

it's much simpler that than, you don't have to as Hibernate will dirty check automatically and avoids any useless SQL.

Dirty check works if I load entity object and within same Hibernate Session update entity object and save.

I use DTOs for incoming data from webpage. This DTO gets tramsformed in Entity object.

Which in turn is saved using Hibernate Session update. But dirty checking is not working in this case.

How can I enable dirty checking in this type of scenario.

I will greatly appreciate any lead on this. If needed I can post my code.

Thanks,

What do you mean by "not working" ? It's always enabled.

Could you show the code about "This DTO gets tramsformed in Entity object" ?
How do you get a reference to the entity object?


What a waste of time. Seam exposes entities directly, to JSF components, others and even to javascript/JSON.
