how to ensure that JDialog always stays on top

java visibility jdialog

I have a JDialog that takes a name from the user. Behind the JDialog, is an applet. I dont want the user to access that applet until he has entered the name. I tried JDialog.setAlwaysOnTop(true), but the applet throws an AccessException error. So what I did was keep a while loop that will execute JDialog.setVisible(true) till the JtextField(input for user name) is empty (""). But for some reason this works really slow, meaning the JDialog loads, but it takes time to focus on the JTextField and even when the user types his name, it comes really slow... like one character in 2 seconds... Is there any other way for me to force the user to enter the name before accessing the applet?

Use a modal JDialog. For example the code in your init(...) method of JApplet might include:

JDialog dialog = new JDialog(SwingUtilities.windowForComponent(this));
dialog.setModal(true);
dialog.setSize(...);
dialog.setVisible( true );

Or you can just use a JOptionPane.showInputDialog(). Again you would just specify "this" as the parent component of the option pane.
