This problem is realated to Classloading problems – you have the two jars inside different classloaders . Make sure that Hibernate and ehcache jar are in the same dir (thus the same classpath and classloader) and make sure there are no duplicates or older versions.

Since you are getting NoClassDefFoundError and not ClassNotFoundException, it means the JAR is there in your classpath but classloader is not able to load this class. May be due to version mismatch. Like you are using JDK1.4 and trying to use a class complied in JDK1.5 or above version. Link might help:

You are missing ehcache.jar from your class path. You must include this jar to get rid of the exception. If you don’t have this jar, you can download it from here
