the errror sessionfactory.getcurrentsession() returns session, not sessionfactory, thereby class cast exception.
remove .getcurrentsession()
@repository public class linedao implements geometrydaointerface { @resource private sessionfactory sessionfactory = (sessionfactory) hibernateutil.getsessionfactory().getcurrentsession();
