I want to check if my swing application is in the the foreground. If that's not the case I would use the application's system tray icon to display balloon notifications for some specific events. Any ideas on how to check that?

Focus subsystem helps you to check whether window is being active or not.
jframe.addWindowFocusListener(new WindowAdapter() {
//To check window gained focus
public void windowGainedFocus(WindowEvent e) {
//set flag
isWindowActive = true;
}
//To check window lost focus
public void windowLostFocus(WindowEvent e) {
//set flag
isWindowActive = false;
}
});

isActive()
and isFocused()
are a good starting point so see whether your frame has focus or not.
WindowListener
may also be used to react on windowActivated
and windowDeactivated
.
