I'm extremely sorry... please ignore. It was an issue on my part.
I'm new to Envers and I've the same issue but didn't find a solution.
Could you please explain how you solved it?
I'm using Spring 2.5, Hibernate 3.3.2 and Envers 1.2.1.
I would check the packaging and that all the jars have downloaded correctly and in the right versions.
thanks for your reply. You're right!
It was because of my eclispe. Eclipse used on old envers jar-file (envers-1.1.0.ga-hibernate-3.3) although I removed it from the Java Build Path and added the new jar-file (envers-1.2.1.ga-hibernate-3.3.jar).
Well, I removed the jar-file from the lib-folder of my project and everything works fine.
Very weird behavior, isn't it?!
