I see that the cacheProvider property of the SessionFactoryBean is deprecated in 3.0. They suggest replacing it with cacheRegionFactory instead, but I'm having some problems...

first: There doesn't appear to be any RegionFactory implementation for ehCache. Can anyone point me at one?

In the meantime, I'm trying to use org.hibernate.cache.impl.bridge.RegionFactoryCache ProviderBridge, like so:
Code:
	<bean id="sessionFactory"
		class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
		.
		.
		.
		<property name="cacheRegionFactory">
			<bean id="cacheRegionFactory"
				class="org.hibernate.cache.impl.bridge.RegionFactoryCacheProviderBridge">
				<constructor-arg>
					<props>
						<prop key="hibernate.cache.provider_class">org.hibernate.cache.EhCacheProvider</prop>
					</props>
				</constructor-arg>
			</bean>
		</property>
	</bean>
But this gives the following Exception at runtime:

Code:

I'm using Spring 3.0.0 RELEASE, and Hibernate 3.3.2 GA.

Has anyone managed to get this working? Or should I just stick with my deprecated cacheProvider implementation?
