将数据插入Oracle。 Java Jframe

Question

一直试图将数据插入oracle。我对其进行了排查，并设法获得system.out.println 1和2.

这是我的代码。 PS。我怀疑使用jDatepicker可能是日期。

   private void AddActionPerformed(java.awt.event.ActionEvent evt) {                                    
    // TODO add your handling code here:


   SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
   String startDate = formatter.format(csd.getDate());
   String endDate = formatter.format(ced.getDate());
   String id = cid.getText();
   String name = cname.getText();
   int year = cyear.getYear();
   String ccountry = country.getText();
   String ccity = city.getText();
   String cvenue = venue.getText();
   String contactemail = email.getText();

  try{

  Connection dbConnection = getDBConnection();
      System.out.println(1);
   String insert = "insert into conference values(?,?,?,?,?,?,?,?,?)";
   PreparedStatement ps = dbConnection.prepareStatement(insert);
   ps.setString(1, id);
   ps.setString(2, name);
   ps.setInt(3, year);
   ps.setString(4, startDate);
   ps.setString(5, endDate);
   ps.setString(6, ccountry);
   ps.setString(7, ccity);
   ps.setString(8, cvenue);
   ps.setString(9, contactemail);
   System.out.println(2);
   ps.executeUpdate();
   System.out.println("louis");
  }
  catch (Exception ex) {
  }

}
