I have JRE 1.5.0.06 installed from Sun, and the site you have on your post 
works fine. the monitor graph is displayed correctly. I had not set up 
Konqueror for Java, but spent some time on this, this afternoon. Konqueror 
does not use the Java plugin, and you have to directly link to the binary. 
Eventually I got Konqueror accessing the binary, which was confirmed by 
running the following URL.

http://www.java.com/en/download/help/testvm.xml

This showed that the applet was working ok. So I tried your site, which said 
that the applet was starting, and the ticker started running at the bottom of 
the monitor screen, but then got the same system failure as you, and the 
graph would not display. the Java console gave a lot of output as below.

I can't make much sense from this, but the continual references to "unknown 
source" seem to be a problem here.

It would be good to have some other sites that need Java to try with 
Konqueror. The only one I have is a French learning site that needs Java for 
it's IRC, but Konqueror locks up using 100% CPU using that, and I have to use 
Firefox.

Anyone suggest some sites that need Java, to try out Konqueror with them?

I also Googled a lot this afternoon, and it seems that lots of folks have 
problems with Java on Konqueror.

Sorry I havn't found a solution to your problem.

Nigel.
