hibernate.cache.region.factory_class Required in hibernate.cfg.xml

I am working on using memcache as second level cache for Hibernate. I am using hibernate-memcached-1.2.4, spymemcached 2.8.0 and hibernate 4.1.4.

But when i try to use it , it gives me error saying

    Initial sessionfactory creation failedorg.hibernate.cache.NoCacheRegionFactoryAvailableException: Second-level cache is used in the application, but property hibernate.cache.region.factory_class is not given, please either disable second level cache or set correct region factory class name to property hibernate.cache.region.factory_class (and make sure the second level cache provider, hibernate-infinispan, for example, is available in the classpath).

Had the same issue while using hibernate-memcached 1.3 and spymemcached 2.7 with hibernate 4.3. Had to switch to hibernate4-memcached which provides a RegionFactory.

The exception is quite self-explanatory. You have to set the *hibernate.cache.region.factory_class* property. For instance with ehcache would be adding the following line:

<property name="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</property>
