Is the applet served from www.wolflodge.org? If not, then it can't access that host for security reasons. See HowCanAnAppletReadFilesOnTheLocalFileSystem for more information and workarounds.

If you control that web site, then sure, just put the applet into one of its pages. But if it's somebody else's web site, I'm sure you can see that you can't just go changing somebody else's web site. You could ask them if they would put your applet into one of their pages, but I can't imagine why they would do that.
