Since Java applets are not supported anymore by basically all important webbrowsers, we choose to provide a Java Webstart file instead. It is not signed with a valid certificate, sorry!
Because the neat embedding of the applet is no longer an option, parameter passing within this wiki is not (yet) implemented. Hence, if you dropped by via the testing page, consider setting the parameters yourself.
Furthermore, something like icedtea or Java Webstart is necessary to start the applet.
