Is it my java or my SQL that is giving me this error???

Question

im trying to push a value from a jsp to a database. it is a date. i have it declared as a String in my java
  private String closed_date = "";
  public void setClosedDate(String closed_date)
    this.closed_date = closed_date;
  public String getClosedDate()
    return closed_date;
  }here is the jsp page where the user enters the date
<input type="text" name="dateClosed" size="10" value="<%=rec.getClosedDate()%>" onKeyPress="return noEnter()">and here is the second jsp where the user is notified that the insert was submitted
    String dateClosed = request.getParameter("dateClosed");
    rec.setClosedDate(request.getParameter("dateClosed"));
    //rec.setClosedDate(Date.valueOf(request.getParameter("dateClosed"))); --- for testing
    System.out.println(dateClosed  + " dateClosed"); //for testingand finally here is my other java file with my sql statement and method
public static final String insertDateQuery =
" insert into Dates " +
" ( " +
" ID, CLOSED_DATE, NAME " +
" ) " +
" VALUES " +
" ( " +
" ID_SEQ.NEXTVAL, to_char(to_date(?,'yyyy-mm-dd'),'mm/dd/yyyy'),? " + // is this my problem??? my SQL to_char or should i be doing something in my java to parse???
public synchronized boolean insertDate(RecDateBean rec)
try
        makeConnection();
        ps = conn.prepareStatement(insertDateQuery );
        //ps.setInt(1, rec.getID());//pk -- SEQ.NEXTVAL
        ps.setString(1, rec.getClosedDate());
        ps.setString(2, rec.getName());
        ps.executeUpdate();
        conn.commit();
      }//try
      catch(Exception e)
        System.out.println("Exception:" + e.toString());
        e.printStackTrace();
      }//catch
      finally
        try
          releaseConnection();
        catch (Exception e){}
      }//finally
      return true;
  }//insertDatewhere am i not parsing that i can not enter this date into the database????any suggestions

Answer 1

so if i use the formatter
  private SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-mm-dd");
i would place it in my java and then change my vars from Strings to Dates
private Date closed_date = null;
  public void setClosedDate(Date closed_date)
    this.closed_date = closed_date;
  public Date getClosedDate()
    return closed_date;
public String getClosedDateFormat()
    if (closed_date == null)
      return "";
    else
      return dateFormat.format(closed_date);
like this and then in my jsp call the
value="<%=rec.getClosedDateFormat()%>"
and still set like this
    String dateClosed = request.getParameter("dateClosed");
    rec.setClosedDate(Date.valueOf(request.getParameter("dateClosed")));
and in my java change my setString to setDate
ps.setDate(2, rec.getClosedDate()); or getClosedDateFormat????
