Now I have recompiled the applet with -version 1.3 so it should run on most browsers (I tested with JRE 1.4.2_01/1.5.0_02-b09, Linux/Solaris/Win32 and the applet loaded on those and played music on atleast the Win32 systems(the others had no speakers)).
I also had the opportunity to write an ant script so its easier to recompile and included a sample with the applet tag in the source.
