We are using the following approach to cache the entities using EJB 3.0 for JBoss.

Persistnce.xml changes :

<persistence-unit name="OracleDatabase" transaction-type="JTA">
  <provider>org.hibernate.ejb.HibernatePersistence</provider>
  <jta-data-source>java:/ClientPointeDS</jta-data-source>

  <properties>
   <property name="hibernate.dialect" value="org.hibernate.dialect.Oracle9Dialect" />
   <property name="hibernate.show_sql" value="true" />
   <!-- These are the default for JBoss EJB3 -->
    <property name="hibernate.cache.provider_class"  value="org.hibernate.cache.HashtableCacheProvider" />
   <property name="hibernate.transaction.manager_lookup_class"  value="org.hibernate.transaction.JBossTransactionManagerLookup" />
            <property name="jboss.entity.manager.factory.jndi.name"         value="java:/EntityManagerFactories/oracleDatabase" />



   <!--  JBoss Cache Related Changes  -->
<!--   <property name="hibernate.cache.use_second_level_cache" value="true"/>-->
<!--   <property name="hibernate.cache.use_query_cache" value="true"/>-->
<!--   <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.jbc2.JndiMultiplexedJBossCacheRegionFactory"/>-->
<!--   <property name="hibernate.cache.region.jbc2.cachefactory" value="java:CacheManager"/>-->
<!--   <property name="hibernate.cache.region.jbc2.cfg.entity" value="mvcc-entity"/>-->
<!--   <property name="hibernate.cache.region.jbc2.cfg.query" value="local-query"/>-->
<!--   <property name="hibernate.show_sql" value="true"/>-->


    <property name="hibernate.cache.provider_class" value="org.jboss.ejb3.entity.TreeCacheProviderHook"/>

     <property name="hibernate.treecache.mbean.object_name"  value="jboss.cache:service=EJB3EntityTreeCache"/>

     <!-- <property name="hibernate.ejb.classcache.services.entities.InstitutionData" value="transactional"/>
      <property name="hibernate.ejb.classcache.services.entities.InstitutionStatus" value="transactional"/> -->

    <property name="hibernate.cache.use_query_cache" value="true"/> 

   <property name="hibernate.cache.region.factory_class" value="org.hibernate.cache.jbc2.JndiMultiplexedJBossCacheRegionFactory"/> 

   <property name="hibernate.cache.region.jbc2.cachefactory" value="java:CacheManager"/> 

   <property name="hibernate.cache.region.jbc2.cfg.entity" value="mvcc-entity"/> 

   <property name="hibernate.cache.region.jbc2.cfg.collection" value="mvcc-entity"/>  

  </properties>



@XmlRootElement(name="institutionData")
@XmlType(propOrder={})
@Cache(usage=CacheConcurrencyStrategy.TRANSACTIONAL)
public class InstitutionData {
  /**
   * Apache Logger reference
   */  
 

 } 

 


 We are getting the following Exception
