You'll need to define that youu have a primary key class
in both your properties file and your deployment descriptor.
In your properties file you'll have something like
...
db.Field.id id
db.Field.clientId client_id
db.Field.franchiseeId franchisee_id
...
db.Finder.findByPrimaryKey where id = ? and client_id = ? and
franchisee_id = ?
my id, client_id and franchisee_id here are all char's, although varchar will
work as well without problems ...

Not sure, if you're using container managed persistence then you'll
only need to define what you want and GenIC will create the
find* methods for you.

Yeah, CheckEJB isn't perfect, but better then nothing ...

Um, something like joe-nas, I keep thinking it's a variant on
Jonah, the whale fodder from the old testament ...
