New to Java

Hello!

I'm trying to self-sign an applet but it seems like it's not working. I've come as far as adding (or trying to add in my case) my certificate to cacerts.

I've followed these instructions : http://forums.sun.com/thread.jspa?threadID=174214

The cmd message below seems to indicate an error.

I can't run the applet in internet explorer. I get the "To help protect your security , Internet Explorer has restricted this webpage from running scripts or ActiveX controls that could access your computer. Click here for options...".

When I click yes window , with the same size of the applet is displayed but the applet is not run. When I look at the details of the error it says:

Undantag (swedish) = exception(english).

My OS is vista 32, ultimate.

I'm grateful for any assistance!
