exception in thread "main" org.hibernate.mappingexception: unknown entity: it.s.monitoringdoor.model.door_open [...]
some advice?
look @ package of door_open class, is: it.selco.monitoringdoor.model while in hibernate.cfg.xml door_open.hbm.xml file at: <mapping resource="it/s/monitoringdoor/model/door_open.hbm.xml"/>. package , mapping resource path not match, should same e.g. it/selco/monitoringdoor/model/door_open.hbm.xml , of course move door_open.hbm.xml in same path class.
hope helps.
ps, why using both annotations (e.g. @entity) , hbm mapping class? think should choose 1 not both.
