The excetion seems to be more of a classpath problem than a hibernate one. It seems that the class "org.hibernate.criterion.Criterion " cannot be loaded - most of the time this problem has one or more of the following reasons:
- The jar file (hibernate-core-x.x.x.jar) is missing in the classpath
- The jar file is in the classpath but one of the imports of the class references a class that is missing in the classpath
- One of the jar files has a defect (check the md5) - compared to the above two reasons this one is rare.
