JOptionPane wont show up.

[Dcalladi]

i have a main class which is a JFrame it call as class called priceCheck()

public class priceCheck {

    public priceCheck(String barcode) {
        try {
            DriverManager.registerDriver(new com.mysql.jdbc.Driver());
            Connection conn = DriverManager.getConnection("jdbc:mysql://samp.inf.brad.ac.uk/dcalladi", "dcalladi", "Dannys21");
            ResultSet rs = conn.createStatement().executeQuery("select Name, FORMAT(Cost,2),Stock_Level where Barcode = " + barcode + "");
            while (rs.next()){
                JOptionPane.showMessageDialog(null, "Name : "+rs.getString(1)+" Cost : "+rs.getString(2)+" Current Stock "+rs.getString(3)+"");
                conn.close();
            }
        } catch (Exception ex) {
        } 
    }
}

obviously i can't have a panel or jframe for the first parameter for the JOptionPane so i heard you can have null and it should still appear but for some reason this dialog box isn't appearing. and i can't think of any reason why it isn't i have tried a System.out.println and it is getting to the class

You probably wouldn't ever consider driving a car with a blindfold on, right? Likewise, don't ignore exceptions with an empty catch block unless you simply don't want to know why your code's not working. At least print a stack trace.
