inserting date into oracle!!!

Hi, I have been trying to insert the current date into ORACLE in vain... my query reads like this.. java.text.SimpleDateFormat formatter = new java.text.SimpleDateFormat("dd/MM/yyyy"); java.util.Date currentTime_1 = new java.util.Date(); String dateString = formatter.format(currentTime_1); // Have to use Java.util.date.... out.println( "<br>" ); out.println( dateString ); // shows current date Fine.. sql = "INSERT into RESERV_DOC_UPD(CODE,DOC_COD,COLAB_COD,RESERVED,DATE_RESERV)"; sql += "VALUES("+temp+","+code+","+COLAB_COD+","+RESERVED+","+(to_date(dateString, dd/mm/yyyy))+")"; Can anyone Please tell me whats wrong with this query and the remedy for it!!??? Thnx a lot in adv, gaucho
