Hi,

I'm using Hibernate for O/R-mapping. I want to create an entity who's
data comes from multiple tables. I already figured out that I have to
use @SecondaryTable to achieve that.

My question is: Is there a way to map an entity to different tables in
different databases? Or do the @Table and the @SecondaryTables have to
be in the same database?

TIA
simon
