Hibernate version:
3.0

I have implemented table-per-class-hierarchy but when I do a select to retrieve an object I want to figure out what the class of that object is. Unfortunately instanceof does not always give me the correct class. Is there a way to achieve this?

Can we have more info? Perhaps a mapping class and just how you are 'running a select'? From your vague message, I can only make assumptions... like are you running a jdbc select statement or an hql statement? It seems like you arne't using hibernate to do your queries...

Basically I have a hibernate class say X. X has one sub class Y. There is another hibernate class Z that holds a collection of X (or Y). When I retrieve the collection and do an instanceof X/Y and if the object in the collection should have been of class Y (sub class) it always shows the object as being of the class X. Thats the problem

When a class X has a subclass Y, and you have an object of Y (y), then "y instanceof X" is true. But when you have an object of X (x), then "x instanceof Y" is false. I hope this helps you?

Yes I understand that. Let me explain the problem again

I have a class X and an subclass Y (using the table per class hierarchy pattern)

Class Z has a collection of objects of X and/or Y

I load Z

I iterate through the collection trying to detect the if the object is of class Y by doing
Code:
currObj instanceof Y

This comparison fails for objects that I know for sure are of of class Y
