[solved] classCastException BigDecimal Oracle ADF BC

Question

Hi,
I am using JDeveloper 10.1.3.3 and ADF BC to persist some data in an Oracle 10g database.
On the db-side we are using a package to perform insert, update and delete-actions. Therefore I implemented ch26.4 from the userguide (Basing an Entity Object on a PL/SQL Package API)
On several tables it is implemented succesfull. However on one table, which contains 37 collumns, the am-methods raises an ClassCastException BigDecimal.
Does you know if there is a limit on the ammount of collums, parameters that you can use for an callableStatement? Or any other idea what can raise such an exception?
Error stack:
java.lang.ClassCastException: java.math.BigDecimal

Hallo Johan,
Thanks for your input. I compared some of my code and found the error...
Hereby the original code:
         setOid((Number) callStoredFunction( NUMBER
                                           , "vac_i_pck_int_scp.maak_relatie(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"
                                           , new Object [] { getBedrijfsnaam()
                                                           , getRsnOid()
                                                           , getTelNr()
                                                           , getFaxNr()
                                                           , getWebSite()
                                                           , getEmailAdres()
                                                           , getOpmerking()
                                                           , getStatutaireVestigingsplaats()
                                                           , getInschrijvingsnrKvk()
                                                           , getPersPublicaties()
                                                           , getOmvangMandaat()
                                                           , getBeleggingscategorien()
                                                           , getPercentageAllocatie()
                                                           , getContractvoorwaarden()
                                                           , getFees()
                                                           , getBandbreedte()
                                                           , getDeelnamePool()
                                                           , getPortefeuilleDiscretionair()
                                                           , getLooptijdMandaat()
                                                           , getMandaat()
                                                           , getRtsOid()
                                                           , getStatus()
                                                           , getKlantcode()
                                                           , getCrossrelatie()
                                                           , getPrijsgevoelig()
                                                           , getVeeleisend()
                                                           , getLoyaal()
                                                           , getBegindatumContract()
                                                           , getEinddatumContract()
                                                           , getDeelmandaatElders()
                                                           , getDeelmandaatBij()
                                                           , getDeelmandaatOmvang()
                                                           , getReden()
                                                           , getBedragMandaat()
                                                           , getBtwNummer()
                                                           , getScpReferentie()
        );                          The NUMBER constant refers to java.sql.Types.NUMERIC.
The Oid attribute in my Entity Object refers to a number(9,0) column.
And this is the code that works...
        BigDecimal bigDec = (BigDecimal) callStoredFunction(NUMBER, "vac_i_pck_int_scp.maak_persoon(?,?,?,?,?,?,?,?,?,?,?,?,?,?,?,?)"
                                   , new Object [] { getVoorletters()
                                                   , getTussenvoegsel()
                                                   , getAchternaam()
                                                   , getCodeGeslacht()
                                                   , getGeboortedatum()
                                                   , getTelNrZakelijk()
                                                   , getTelNrPrive()
                                                   , getTelNrMobiel()
                                                   , getFaxNr()
                                                   , getEmailAdres()
                                                   , getOverigeVertegenwoordiging()
                                                   , getOrganisatie()
                                                   , getVttOid()
                                                   , getAttOid()
                                                   , getMdwOid()
                                                   , getScpReferentie()
       try {
           setOid(new Number(bigDec.doubleValue()));
       } catch (SQLException f) {
           // TODO
       }Regards,
