Kan ikke smide data i excel

Når jeg forsøger at lægge data i en excel file får jeg fejl. Min kode seer således ud:

       
        StringBuffer buffer = new StringBuffer();
        for(int i=0;i<kolonner.length;i++){
            buffer.append(kolonner[i]+" VARCHAR(250),");
        }
        buffer.deleteCharAt(buffer.length()-1);

        try{
           
            Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
           
        }catch(ClassNotFoundException e) {
            e.printStackTrace();
        }
       
        try{
           
            Connection con = DriverManager.getConnection("jdbc:odbc:;Driver={Microsoft Excel Driver (*.xls)};READONLY=FALSE;Dbq=C:\\kartotek.xls;");
            Statement stmt = con.createStatement();

            stmt.executeUpdate("CREATE TABLE "+objektNavn+" ("+buffer+")");
           
            for(int i=0;i<objektListe.size();i++) {
               
                MK_Kartotek kart = (MK_Kartotek) objektListe.get(i);

                stmt.executeUpdate("INSERT INTO "+objektNavn+" " +
                "VALUES(" +
                "'"+kart.getNavn()+"'," +
                "'"+kart.getAdresse()+"'," +
                "'"+kart.getPostnr()+"'," +
                "'"+kart.getBy()+"'," +
                "'"+kart.getKontaktperson()+"'," +
                "'"+kart.getEmail()+"'," +
                "'"+kart.getHp()+"'," +
                "'"+kart.getLevereingsAddresse()+"'," +
                "'"+kart.getMobil()+"'," +
                "'"+kart.getBank()+"'," +
                "'"+kart.getCvrnr()+"'," +
                "'"+kart.getTlf()+"'," +
                ")");
            }
           
            stmt.close();
            con.close();
        }catch(SQLException a) {
            a.printStackTrace();
        }


Fejlen jeg får er følgende:

Det er ikke meget den fortæller den fejlmeddelse. Kan nogen se hva jeg gør galt?
