I have a java program with a JFrame and when I set it to - JFrame.setAlwaysOnTop(true); I get this error when on the web:

 Exception in thread "AWT-EventQueue-2" java.security.AccessControlException: access denied (java.awt.AWTPermission setWindowAlwaysOnTop)

Is there a way to use this command when on the web?

Thanks,

Hmm... A lot of work for a simple process; would JWindow or Dialog work in this manner and be able to stay on top of all other windows without singing the applet?

no JDialog would just stay on top of its parent.

Reasoning for the security restriction is so uninvited applet don't force windows to display on top of your other windows.
