Hi ,
I have a Java class(A) which is a mapping to a lookup table. Its primary key is referenced as a foreign key in another java class(B) which has a many to one mapping from that other java class(B) to this java class(A).
When i try to create a Criteria based on the first java class(A), with specifying a value for one of the attributes of this class(A), it throws a MappingException specifying that Class(A) as an unknown entity.
[b]Hibernate version:3.0.5
