            }
            catch (ClassNotFoundException cnf)  {
                JOptionPane.showMessageDialog (null, "Driver not Loaded...");         
                System.exit (0);
            }
            catch (SQLException sqlex) {
                JOptionPane.showMessageDialog (null, "Unable to Connect to Database...");
                            sqlex.printStackTrace();
                System.exit (0);
            }

This is not able to connect to the Library database. I have created a ODBC data source Library.

This is the error message:
