Some things I just thought:
I need the html-code that starts the plug-in. Well, how can I get it? It's somehow hidden that litlle cgi that is located in oem_webstage's cgi-bin directory, right? Okay, when I start that cgi with some paramter ("gerald" in my case), I get this output:

Looks nice, right?
So why not try a applet-tag like this:
<applet

 codebase="http://vangogh.fmi.uni-passau.de:1974/oem_webstage/"  code="oracle.sysman.vtcConsole.VTCConsole"  archive="consoleStage1.jar"
 width="2"
 height="2"
>
<param name="BootPort" value="7771">
<param name="BootHost" value"vangogh.fmi.uni-passau.de">
</applet>

Unfortunately, this doesn't work, it throws some exceptions. There's an illegal argument exception and some problems with digital signatures of jar-files :-(
Might have something to do with the cryptic number at the beginning of that object-tag ("classid").
Perhaps someone could help here?

Other thought: Could the java-code of the EM execute in the standard Netscape JavaVM?
