Netscape's security model restricts what applets that are
loaded via the network are allowed to do. One of these things is that
sockets can't be created to connect to a host other than the one the
code was loaded from. This means you need to do one of two things:
*) Run an httpd on the machine you want to connect to
*) put the class in a directory in your CLASSPATH and
it will be loaded from local disk, avoiding the
restrictions.
I'm writing the networking part of a book on Java (Java
Unleashed from Sams.net, comming out in Feb/March, plug plug :), and
I've had plenty of fun trying to get things to work from NS. But the
good news is that a later version will have more flexibility with
security models (check out java.lang.SecurityManager and the Security
faq at:
http://www.javasoft.com/docs/sfaq/
for more information). Hope that helps.
