<SplashScreen-Image>images/splash.png</SplashScreen-Image>
To your MANIFEST.MF. You can have a build tool such as maven add this automatically.
There is also the posibility to simply use a JWindow as a splash screen, but it won't show until the JVM is running. Using the method stacker described(which is the same as the one I point out) you'll show the splash even before the JVM has finished loading, which might be necessary on older hardware.
