IcedTea Java plugin cannot load applet jar file

Hi!

Is this the place to get some IcedTea support...? :)

I have terrible trouble getting the simplest Java applets to work...

System is Peppermint 3 (32 bit) with original Firefox and Debian package
"icedtea-plugin".

I can see some applets, like this one: http://math.hws.edu/xJava/MB/

But a very simple test applet does not work:
http://sessions-hamburg.de/applet/applet_noswing.html

There is an exception in ~/.icedtea/log/java.stderr:

java.lang.ClassNotFoundException: ma.ma01.NoSwingApplet
    at
net.sourceforge.jnlp.runtime.JNLPClassLoader.loadClass(JNLPClassLoader.java:1404)

...which is apparently caused by an unability to load the applet's jar file
(I saw an exception about that somewhere else I think). However, the jar
file is clearly there: http://sessions-hamburg.de/applet/MagicApplet.jar

And the weird thing is, the applet viewer loads the applet just fine! (Try
"appletviewer http://sessions-hamburg.de/applet/applet_noswing.html" on
your command line, does it work? The applet should just say "Hello world".)

Finally, I cannot get a Java console to pop up even if I select that in the
IcedTea configuration screen.

Hehe... sorry if this question is boring or something - it's very important
to me, I need to write an important applet.

Best regards,
Stefan
