Is it possible to declare a particular naming convention, in this case CamelCase over _underscore, on a particular model?

Hibernate use underscore as default, but I require 2 models of my models to use camelcase instead of underscore as database column. Is it possible to set a configuration on only 2 models, while leaving the rest of the models as default (meaning _underscore convention in column name).

example:
default hibernate: model class variable: rowId - database column: row_id.
What I need: model class variable: rowId - database column: rowId

If anybody has any information, article, tutorial it would be greatly appreciated.

Thanks,
Marcin
