1. org.hibernate.validator.ClassValidator missing

Hi, I had to update my hibernate version due to some damn MySQL errors. I replaces the old validation-lib with "hibernate-validator-4.0.2.GA.jar" but now eclipse can't find the class org.hibernate.validator.ClassValidator. May anybody tell me how to fix that? Additionally "org.hibernate.cfg.AnnotationConfiguration" seems to be problematically. Which jar-file contains this class? I need it for "HibernateUtils". Thanks a lot for any help. Jonny
