Ok, I'll start a new try to explain the problem:

1)  arbitrary Applets work in IE on other Websites in the Internet
2)  my Applet *does* work in IE, if I open the file directly from my desktop
3)  my Applet does *not* work in IE, if I serve the HTML and JAR files
through Tomcat

4)  arbitrary Applets work in FF on other Websites in the Internet
5)  my Applet *does* work in FF, if I open the file directly from my desktop
6)  my Applet *does* work in FF, if I serve the HTML and JAR files through

In addition I've traced the output of the Java Console, when loading the
Applet through Tomcat in IE (case 3 above)

Here's the log:

Java Console at Page-Reload in IE:

basic: Starting applet teardown
basic: Finished applet teardown
basic: Fortschritts-Listener hinzugefĆ¼gt:
basic: Applet geladen
basic: Applet resized and added to parent container
basic: PERF: AppletExecutionRunnable - applet.init() BEGIN ; jvmLaunch dt
111675 us, pluginInit dt 65177365 us, TotalTime: 65289040 us
basic: Applet initialized
basic: Fortschritts-Listener entfernt:
basic: Applet made visible
basic: Starting applet
basic: Applet started
basic: Told clients applet is started 

To me this looks like the applet is correctly loaded, started, etc., i.e.
the java-side work out well, but the IE refuses to show the applet.

I assume, this is no java-applet-security-problem (like a not
signed-jar-problem), because there is no 
AccessControlException or stuff like that.
