ClassCastException after upgrading to 2.2.0.GA

gfpelly1 Sep 21, 2009 7:31 AM

I get the ClassCastException with the components.xml file below. If I change the name of the hibernate session to anything other than 'session' then I get a different error saying the session was null.

A ClassCastException usually means that you have a class loader conflict (e.g. the class is contained in two jars, but with a different library version).
