I have this scenario:

table A:

id - primary key
X - references table B

table B:
id - primary key

column X of table A references table B and is unique, not null in table A (many-to-one).

I want to know how I can map this in the .hbm.xml file with a corresponding finder method.

Can I use finder meta tag inside many-to-one for this scernario.
I tried this, but when it generates the .java file, the object type for table B is null, is passed as the third argument inside the finder method based on X.

Could you please help me here.

I need a findByX method which accepts session, object X and returns the list without any nulls.

Thanks,
splguy.

You need to detail the problem a little better if you want an answer, preferably by checking out: http://www.hibernate.org/160.html

What table is object X mapped to? Where are your mapping files.?
