java와 오라클 간의 Date Format 맞추기

 public int UserDataInsert(UserData ds) throws SQLException{
  Connection con = connectDB();
  PreparedStatement ps = null;
  int result = 0;  
  Calendar cl = Calendar.getInstance();
  cl.setTime(ds.getVocStartdate());
 
  try{
   ps = con.prepareStatement("INSERT INTO VOCMASTER (PROCID,CUSTNAME,CUSTEMAIL,CUSTMOBILE,CUSTAGE,CUSTGENDER," +
           "VOCSTARTDATE,VOCTITLE,VOCTYPE,VOCCONTENT) " +
           "values (?,?,?,?,?,?,TO_DATE(?,'YYYYMMDDHHMISS'),?,?,?)") ;
   long ut = cl.getTimeInMillis();
   DateFormat df = new SimpleDateFormat("yyyyMMddhhmmss");
   String ll = df.format(ut);
   System.out.println(ll);
   ps.setString(1, ds.getProcId());
   ps.setString(2, ds.getCustName());
   ps.setString(3, ds.getCustEmail());
   ps.setString(4, ds.getCustMobile());
   ps.setString(5, ds.getCustAge());
   ps.setString(6, ds.getCustGender());
   ps.setString(7, ll);
   ps.setString(8, ds.getVocTitle());
   ps.setString(9, ds.getVocType());
   ps.setString(10, ds.getVocContent());
   

   result = ps.executeUpdate();  
   ps.close() ;
   con.close() ;
  }catch(Exception e){
   System.out.println("Cannot execute query: " + e.getMessage());
  }
 
  return  result;
 }

}

바쁜 관계로 주석은 다음에 남기겠습니다.. ㅡㅡ;;;
