ERRORCODE=-4220, SQLSTATE=22003 on java select from DB2

Question

i'm having the following exception with this method, any guess? The same exception is thrown even if i change the parameters of the function, i also tried with String but the problem is the same.

public void getDettagliLottoPerPersonalizzazione(BigDecimal numeroLotto, BigDecimal progressivoApparato, BigDecimal numeroScatola) throws Exception
    {   
        List<DettaglioLottoPersonalizzazioneDTO> dettaglioLottoResult = null;
        Query query = null; 
        try
        {
            logger.info("Ricerca dettaglio lotto da personalizzare per numero lotto " + String.valueOf(numeroLotto) );                          
            XmlQueryReader prop = XmlQueryReader.getIstance();
            String queryDettaglioLotto = prop.getQuery(this.getClass().getSimpleName(), "queryLetturaDatiPerPersonalizzazione");                    
            query = entityManagerView.createNativeQuery(queryDettaglioLotto);
            query.setParameter(1,numeroLotto);
            query.setParameter(2,numeroLotto);
            query.setParameter(3,numeroLotto);
            List<Object[]> result =  query.getResultList();
            for (Object[] objects: result) {
                System.out.println((String)objects[0]);
                System.out.println((String)objects[1]);
                System.out.println((String)objects[2]);
                System.out.println((String)objects[3]);
            }
        }
        catch(Exception  e)
        {
            logger.error("Errore durante la ricerca del dettaglio lotto da personalizzare per numero lotto "  + String.valueOf(numeroLotto) + ". " + e.getMessage());
            throw new Exception("Errore durante la ricerca del dettaglio lotto da personalizzare per numero lotto "  + String.valueOf(numeroLotto));
        }
        logger.info("Ricerca dettaglio da personalizzare numero " + String.valueOf(numeroLotto) + " avvenuta con successo");
    }

Here's the exception

The same query executed on DBeaver works fine.
