If EDT is "totally" blocked by your EJB method such that no event processing occurs at all, then there's nothing you can do. In that case you have to move the EJB call to a SwingWorker.

If EDT is only "partially" blocked, for example by a modal dialog, then you can add an ImageObserver to your ImageIcon, and repaint the icon in imageUpdate (e.g. call paintImmediately if your icon is set on a JLabel).

Take a look at JXBusyLabel, it has some defaults and support for BusyPainter as well that controls the image/animation you want to be displayed. Check here for a basic tutorial.
