The default security model in most browsers allows an applet to open
TCP/IP connections only to the host from which it was loaded.  For
example, if your applet is at http://www.foo.com/javastuff/stuff.jar,
it will be able to load


but *not*


I think that that's getting better in newer browsers, but I haven't
looked for a while.  The JDK plug-in from Sun might also help.

Look at the bright side -- at least there's no equivalent of Melissa
in the Java world, yet (imagine if hostile applets could start
connecting to arbitrary SMTP hosts).

All the best,
