How to configure second level cache in Hibernate 4.3

Question

I have read post related with this but not get any answer working for me. I am configuring second level cache in Hibernate v4.3. And I have used MySQL 5.0

I have written following elements in hibernate.cfg.xml

true
org.hibernate.cache.ehcache.EhCacheRegionFactory

I have annotated my Entity class for cache as follows

@Entity 

@Cache(usage = CacheConcurrencyStrategy.READ_ONLY)
public class Employee { ....}

Following exception is shown when run

INFO: HHH000397: Using ASTQueryTranslatorFactory

I have seen than there are different cache providers for Hibernate v3 like EhCacheProvoider. All are in org.hibernate.cache package. But for Hibernate 4.3 there are only 3 classes as RegionFactory.class and other two are of exception.

1. What is wrong with above code?

2. What are major changes made for Second level cache configuration in Hibernate 4.3?
