Hibernate version: 3

Mapping documents: <property name="age" column="age" type="integer"/>

I have to support an old database with a poor design. In the old EJB implementation there are several columns that have int or long mapped to a nullable database column. For now I need to simply convert any nulls I encounter to 0 is it possible to do this with an integer type?

If not can I do this with a custom datatype? If so where can I find a good examlpe?

Thanks!

Jamey...

If you are using java beans ..simply modify the default values of the properties from null to 0..

use a usertype...

maybe try to contact the poster of this topic:

to see if they got theirs done.

if not, search the wiki for examples.
