Java with Konqueror on FC2

[Nigel Henry]

I have jre-1.5.0.6 installed. The .bin version. Using Firefox I have no 
problem with applets using the java plugin, but Konqueror doesn't use the 
plugin so I have to set the Java path to, in my case.
/usr/java/jre1.5.0_06/bin/java

I tried this site, which someone on the KDE list was having a problem with.

This works fine on Firefox, and Opera, but not with Konqueror. On the right of 
the main page is a box named monitor. The ticker at the bottom of the box 
works ok, but the main applet lunches out with some Portuguese words meaning 
"system failure", and the Java console shows this.

Today, as I'm about to update the Smootwall, and looking through the various 
stuff on the web interface, I saw there was a shell connection using SSH, and 
uses a Java applet. Going for this I tried it on Konqueror. It got as far as 
"loading applet", then didn't do anything. The same trial with Firefox using 
the Java plugin worked fine and the applet loaded. The output from the 
Javaconsole for the failed Konqueror trial is below. Konqueror says "loading 
applet", then the output to the Javaconsole, then Konqueror says "applet 
failed"

Error during state 1

I'm not up to speed with Java, but does anyone know what this output is 
saying, and what might be a possible fix to get these applets to load on 
Konqueror?

I do also have FC1,3,4, and 5 installed, but it would be nice to get a bit of 
feedback before I go installing the JRE on FC5 for instance.
