Accessing web sites is easy in Java. Use the URL/URLConnection
classes. Or my com.oreilly.servlet.HttpMessage which abstracts things
a little more. See http://www.servlets.com/.
To poke through a firewall you need to set some system properties.
See:
http://www.javaworld.com/javaworld/javatips/jw-javatip42.html.
You may also want to set socksProxySet, socksProxyHost, and
socksProxyPort for SOCKS-based proxies.
