It tries to load http://raneez.frih.org/app/appCrash/class.class, and that location doesn't exist. Could you show the code where you load the appCrash class?

Funnily enough I'm having the same problem...

The java applet tries to open...

I took some time away from Java cos it started to get all frustrating. I came back to it and spent some time with my head in the Tutorials on Sun Microsystems' website. The problem is simple. I had compiled an application and was trying to open it as an applet. I now have working "Hello world!" applet code.

raneez_n I suggest that you post your java code so that someone can look at it and make it work in an applet rather than just working as an application.

Please see my post if you wish to see my working applet code.
