Thanks of the suggestion, I managed to run the app after long time looking for the solution. It looks that the configuration on persistance.xml was never being setter or being overwritten. My solution was to set: hibernate.cache.region.factory_class = org.hibernate.cache.ehcache.SingletonEhCacheRegionFactory on the system.properties in the conf file from tomee.
Now the app it is running but it looks that my queries are never hitting the cache and it is always quering the DB even though i am annotating my entity with @Cachable and @Cache. Any suggestion?
