I have a class B which extands class A. I am writing a HQL using these two classes. In B's mapping file i have only B's fields. When I execute the HQL A is replaced with B and I am getting exception that the field info is not found.

like
SELECT a,b,c

FROM

A a, B b, C c

Where

a.id = c.id
AND c.id = b.id

is interprated as

SELECT a,b,c

FROM

B a, B b, C c

Where

a.id = c.id
AND c.id = b.id

How do I mention in B's mapping file that A's info is in A's mapping? I can't change the class structure for any reason.

The hibernate version is 2.1.7

Thanks in advance.

Assuming that you have auto-import="true" in your configuration file, you don't need to mention A in B's mapping file unless you want to alias A.

If you're seeing B's table when you query on A, it's most likely due to the way you've declared the inheritance in your mapping. Perhaps you've accidentally said that A's mapping extends B, instead of the other way around. You'll probably have to post your mappings for a more detailed analysis.
