I want to create a generic method of creating backups of my mapped entities.
They all look like this:


I already found out, that i can iterator over all mapped classes, using the sessionfactory's getAllClassMetadata.

But if i use now the ClassMetaData's getIdentifierPropertyName it returns null (i assume, because i have a composite id). The problem is that the fields of the the composite-id do not show up in the getPropertyNames String array.

Further, some of the classes have a named identifier (mappedBy); so how can I "dive" into that class, too, in the same gerenic approach ?
