java.lang.ClassNotFoundException: net.sf.ehcache.hibernate.EhCacheRegionFactory cannot be found

[Jason Trinidad]

Hello everyone,

I am trying to add 2nd level caching to an existing Eclipse project. It is using hibernate 3.6.0.final, so I added hibernate-ehcache-3.6.0.final, and ehcache-core-1.5.0. I added to my hibernateProperties the following lines, 

<prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>

<prop key="hibernate.cache.provider_configuration">config/ehcache.xml</prop>

<prop key="hibernate.cache.use_second_level_cache">true</prop>

<prop key="hibernate.cache.use_query_cache">true</prop>

But I get an exception when I run the code

java.lang.ClassNotFoundException: net.sf.ehcache.hibernate.EhCacheRegionFactory cannot be found

I've tried multiple things, 

Tried upgrading to:

hibernate 3.6.10.final, hibernate-ehcache-3.6.10.final, and ehcache-core-2.4.3

, but I just got the same error.

I also tried changing 

<prop key="hibernate.cache.region.factory_class">net.sf.ehcache.hibernate.EhCacheRegionFactory</prop>

to

<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>

But I got the error: java.lang.ClassNotFoundException: net.sf.ehcache.CacheException cannot be found

I also tried 

<prop key="hibernate.cache.provider_class">net.sf.ehcache.hibernate.EhCacheProvider</prop>

but go an error java.lang.ClassNotFoundException: net.sf.ehcache.hibernate.EhCacheProvider cannot be found

I'm using Windows 7, and Eclipse Kepler

Any clues would be appreciated.

Thanks.

hey,

I think you need to use a different factory that is actually part of the "hibernate-ehcache-3.6.0.final" jar ( org.hibernate.cache.ehcache package)

eg. 

hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.EhCacheRegionFactory

or

hibernate.cache.region.factory_class=org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory

Let us know.

Thanks,

Fabien
