Using Hibernate 3 is it possible to create a criteria query that will exclude subclass from the results:

class Foo
class Bar extends Foo

Bar is mapped in hibernate as a subclass of Foo (joined-subclass in my case)

I would like to be able to write a criteria query that returns only objects whose class is Foo, not objects whose class is Bar.

Does anyone know if this is possible?

It's easy enough to write code to strip Bar instances from the results after the query has been run but this is ugly.

Thanks

hi pei
try to filter it by discriminator field

You should do something like:

if it wasn't partially broken!

If you are using string discriminator types, a hibernate bug prevents a proper usage of this feature,
