....
String User = usernameLoginTxtField.getText();
String Password = pwLoginField.getText();
String SQLString = "select * from Administrators where username = '"+User+"' and password = '"+Password+"'";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver");
con = DriverManager.getConnection(DriverPrefix+DataSource, dbuser, dbpasswd);
stmt = con.createStatement();
