You can't, the JDialog event if is modal is not a system modal dialog, but a Java modal dialog. So the flag modal will not work "outside" a Java enviroinment.

Put this line in the constructor of your class that extends JDialog :

super(JOptionPane.getFrameForComponent(theparentComponent), "Title", true);

I hope it will help you.
best regards,

you have to use the appropriate parent Frame

try something like this

Frame modalFrame;
Component c = applet;
while ((c != null) && !(c instanceof Frame)) c = c.getParent();

if (c != null)
  modalFrame = (Frame)c;
else
  modalFrame = new Frame("dummy modal");
 
 
JDialog dialog = new JDialog(modalFrame, ...);
