Com.apple.mrj.JManager.JMAppletSecurityExc: security.checklisten: 113

Question

I work on a Mac OS9 and the site I use has just started using PJIRC. I cannot access the site and get this message in java messages when I try to:
5/11/2004 @ 8:30:39

The sign in screen comes up ok and I can sign in, also the applet loads, but then I just get a large white rectangle on the screen. I don't know if this is server side or pjirc side.
I would be grateful if anyone can see if there is any code missing on this as I really don't know anything about it and just trying to look around and find someone with answers. Ty in advance.

I can't post it all, too much reading but the explanations can be found @ http://www.skylit.com/javamethods/appxf.html#badcast
