We are developing an osgi bundle with hibernate, which is deployed on the apache karaf 3.0.2. We have a clustered environment.
And as Level2 caching provider, we were trying to use Hazelcast, But we are not able to get it working.
We are getting "Unable to load com.hazelcast.hibernate.HazelcastCacheRegionFactory " error
Here is what we are doing, if we remove below code, it works fine.
1. In persistence.xml
Code:
<property name="hibernate.cache.use_second_level_cache" value="true"/>
<property name="hibernate.cache.use_query_cache" value="false" />
<property name="hibernate.cache.use_minimal_puts" value="true" />
<property name="hibernate.cache.region.factory_class" value="com.hazelcast.hibernate.HazelcastCacheRegionFactory" />
3. Installed the following bundles:
Code:
<bundle>mvn:org.hibernate/hibernate-core/4.2.7.Final</bundle>
<bundle>mvn:org.hibernate/hibernate-entitymanager/4.2.7.Final</bundle>
<bundle>mvn:com.hazelcast/hazelcast/3.4</bundle>
<bundle>mvn:com.hazelcast/hazelcast-all/3.2.3</bundle>
<bundle>mvn:com.hazelcast/hazelcast-hibernate4/3.0</bundle>
<bundle>mvn:net.sf.ehcache/ehcache/2.9.0</bundle>
<bundle>mvn:org.hibernate/hibernate-osgi/4.2.2.Final</bundle>
<bundle>mvn:com.hazelcast/hazelcast-hibernate/xxx</bundle>
Are we missing anything? Please help...
This is the error we are getting:
