It's a security thing. I think an applet can read data from the same domain as it was served from, but not others.
There may be a way around it if you can sign the applet. Search for "sign applet" on this forum for more hints.

Is there anyway around this problem without using a signed applet?

you could use a simple server side script (PHP/Perl+LWP etc.) on your server to retrieve the external data and redirect it to your applet.

see Taka's html visualization, which reads information from a URL without having a signed applet. Search for "taka" -- or, search for applet signing which may help.
