I'm gonna answer my own question but I still need clarification: 1.- Entity caching is done by configuring <property name="hibernate.cache.use_query_cache" value="true"/> in persistence.xml. The cache will start showing up entities, but entities will never be accessed from the cache (this is the point that i need to clarify). 2.- If besides the above, the entity is configured with the HINT @QueryHint(name="org.hibernate.cacheable",value="true"), then queries will also be cached, and if a query is repeated, results will be retrieved from cached. It seems caching entities don't make any sense if query caching is not enabled. Is it that way? Thanks a lot !!
