The class you are missing is in a package org.hibernate, so it should come from Hibernate, no with EhCahe. (Although I imagine it would also depend on EhCache) What dependencies from hibernate have you included? –  madth3 Mar 10 '12 at 2:25
    
This is the list of hibernate Maven artifacts: docs.jboss.org/hibernate/core/4.0/quickstart/en-US/html/… –  madth3 Mar 10 '12 at 2:26

The dependency you're looking for is the following I think (Perhaps a different version)

<dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-ehcache</artifactId>
    <version>3.6.2.Final</version>
</dependency>

I searched for the missing class using Maven Central's search site:

http://search.maven.org/#search|ga|1|fc%3A%22org.hibernate.cache.EhCacheProvider%22

For anyone who is confused why newer hibernate-ehcache 4.x.x artifacts don't contain org.hibernate.cache.EhCacheProvider: In "newer" Hibernate versions, the configuration parameters have changed... in 4.x.x versions, it's correct to use the following: jpaProperties.setProperty("hibernate.cache.region.factory_class", "org.hibernate.cache.ehcache.EhCacheRegionFactory"); –  Abdull Jan 29 '13 at 22:19

When I ran into this problem, it was because I was trying to update the version of hibernate. When moving from hibernate 3.2 to 3.3, the packages split. I had tried to replace hibernate with hibernate-core. Reverting back to the full hibernate package (at 3.2 level) fixed my problem.

During my next round of updates, I will probably need to replace the full hibernate package with hibernate-core and hibernate-ehcache as referenced above.
