JFrame instance called from a Thread

Question

Hi All,
I have an application that fetches data from a database. I have a thread that displays a 'Please wait' message in a JFrame while the software fetches data from the databse.
The trouble is that the message does not appear on the JPanel untill the data is completely fetched from the database.
The frame appears with a button, but no message on it!
Please help.
Thanks.
Anuj.
Code :
// calling method
InformationBox ib = new InformationBox("Please wait while the software fetches data from the database");
ib.setTitle("Please wait");
ib.setLocation(100,100);
ib.setVisible(true);
ib.pack();
public class InformationBox extends javax.swing.JFrame implements ActionListener {
JButton ok = new JButton("OK");
JPanel text = new JPanel();
JPanel okp = new JPanel();
JLabel center = new JLabel();
FlowLayout f1 = new FlowLayout();
FlowLayout f2 = new FlowLayout();
BorderLayout b1 = new BorderLayout();
String comments ="" ;
public InformationBox(String sd) {
this.comments=sd;
jbInit();
public void jbInit() {
this.getContentPane().setLayout(b1);
text.setLayout(f1);
text.add(center);
center.setLayout(new FlowLayout());
center.setText(comments);
ok.addActionListener(this);
okp.setLayout(new FlowLayout());
okp.add(ok);
getContentPane().add(center, BorderLayout.CENTER);
getContentPane().add(okp, BorderLayout.SOUTH);
public void actionPerformed(ActionEvent e) {
if (e.getSource() == ok) {
//eq.setEnabled(true);
this.setVisible(false);
}
