Hi,
i opened 2.level cache and query cache in persistence.xml like following:
			<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.cache.use_query_cache" value="true" />

and on an entity: 
@Cache(usage = CacheConcurrencyStrategy.NONSTRICT_READ_WRITE)
for 2. level cache

and 

	query.setParameter("vorname", vorname).setParameter("nachname",
  | 		nachname).setMaxResults(maxResults).setFirstResult(firstResult)
  | 		.setHint("org.hibernate.cacheable", new Boolean(true)).setHint("org.hibernate.cacheMode", CacheMode.GET ).setHint("org.hibernate.fetchSize", new Integer(100));
  | 
for query cache...

but it doese not work :(
