Hi,

For a projet we have a full mapping configuration that feets 90% of projects.
But in some cases we have 2 different projects using the same root project with it mapping.
We use XML mapping (old projects)
CASE : one projet has to overide mapping on its side ; add column/relation in a persisted object

Is it possible and how, to overide class mapping only in this project wihout having to get all the XML file and change it ?

XML mappings can override annotation ones. But the XML mappings can't be overridden. You need to break the mappings and only chose the ones that are appropriate for your project.

ok thanks.

So in that case I'll have to split hbm file in several files and change my configuration settings in order to inject hbm file I want.
If I used anotations it would be easier, because I would set Spring configuration, scanning the package with the Entity I want.
