is possible pass null value in stored procedure call using hibernate , javax.persistence?

i'm trying in way:

storedprocedurequery storedprocedure = em.createstoredprocedurequery("my_procedure_name"); storedprocedure.registerstoredprocedureparameter("p_lease_null_me", integer.class, parametermode.inout); storedprocedure.setparameter("p_lease_null_me", null); storedprocedure.execute();
