Unsigned applet can only open connections to the host
from which it originates. That is, if the ftp server
that your applet trys to connect to is in the same
host as your web server which is delivering your applet,
it's ok. Otherwise, SecurityException will occur.
This restriction on applets is forced by SecurityManager
of web browsers. So your applet could run successfully
using appletviewer which enforces somewhat relaxed
security policies. What applets can and can't do is well
described at http://www.javasoft.com/sfaq/index.html.
Currently this restriction can be overcome by applet
signing. But unfortunately, Netscape and IE need different
methods to acquire required capabilities.

Hope this helps.

P.S. I think you crossposted your article to too many newsgroups.
     I've even seen your article in Korean one in which most articles
     are written in Korean. If you have no proper reason to post
     articles to a specific group, you'd better not, IMHO.
