I am trying to configure JBossCache 3 as 2nd level cache for Hibernate 3.3.1.GA. Official-looking http://galder.zamarreno.com/wp-content/uploads/2008/09/hibernate-jbosscac... says caches ought to be configured like so (see p.24): anonymous wrote : | <?xml version="1.0" encoding="UTF-8"?> | <cache-configs> | <!-- A config appropriate for entity/collection caching. --> | <cache-config name="optimistic-entity"> | ... | On the other hand, http://www.jboss.org/file-access/default/members/jbosscache/freezone/docs... instructs this format (p.105): anonymous wrote : <?xml version="1.0" encoding="UTF-8"?> | <jbosscache xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" | xmlns="urn:jboss:jbosscache-core:config:3.0"> | | --> | | | .... | Is the latter the correct one? If so, then I am guessing the earlier format was used with JBC2 and was deprecated in JBC 3? If that's the case then should I be using RegionFactory/CacheProvider *other* than one supplied with Hibernate 3.3.1.GA - org.hibernate.cache.jdbc2.JBossCacheRegionFactory? This RegionFactory expects cache config in <cache-config/> format. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4210100#...
