Hi all,
i'm using hibernate 3.1.3 and would like to know if it's possible to have multiple primary keys in one single entity and how to define them with the mappings file? Could you point me to some documentation about it?

Thanks for your help.

You can only have one primary key by definition. You may have multiple columns that are specified to make up the primary key.

If your primary key has multiple columns look for the composite-id section of the Hibernate_reference.pdf file. It has an example of how to map that.
