java - Hibernate Inheritance: Load all entities but no subclasses -

given 2 classes

@entity @table(name = "a") @inheritance(strategy = inheritancetype.table_per_class) public class a{ ... }

and

@entity @table(name = "b") public class b extends a{ ... }

when calling

sessionfactory sessionfactory = ...; session session = sessionfactory.opensession(); session.createcriteria(a.class).list()

i receive instances of and b.

how query instances of (no subclasses of a)?
