Hibernate version: 3.2, annotations version 3.3.1

Mapping documents: annotations

Name and version of the database you are using:Oracle 11i

Hello all.
I have used Hibernate before but I am new to annotations. I need to map a class to DB. In the class there is a Timestamp property which I would like to map to Date field in DB and I want to use @Version annotation on this field. It works fine but the time that is written to DB Date field is jvm time and not DB time. I could not find any way how to switch it to DB time with annotations. I do not want to use XML descriptor to override annotation, since I also use hbm mappings - plus I saw that documentation on XML descriptors is in poor state at the moment. I was forced to switch to hbm for my class and I used <version type="dbtimestamp",...></version>. This is working fine. Is there any way to get the same functionality with Annotations?

I'm having the same problem... Want to specify dbtimestamp in my annotation but am finding it's not working!

Hi,

the db timestamp feature is Hibernate specific. Currently Hibernate Annotations only implements javax.persistence.Version which does not have a type attribute. I believe you will have to stick with xml if you want to keep this feature for now.

Retrieving the time from the db is also not supported by all databases and implies that for each increment the db needs to be accessed. If you are not working with a legacy db it is recommended to use a number for versioning.

Thanks. Indeed we had to stay with xml for that reason. Thanks for reply though.
