This works fine for me. Are you behind a firewall or Proxy Server? If you are you need to set the ENV variables for the http.proxyHost and http.proxyPort to be able to connect through it.

Your browser has the settings for the firewall. On IE, you'll see these under Tools/Internet Options, Select the "Connections" tab Click the "LAN Settings" Button. The setting "Use proxy server for LAN" will be checked. Click the "Advanced" Button.
Under Servers for HTTP, will be listed a server name or IP address and Port Number.

Start the application with
java -Dhttp.proxyHost=<HOST NAME> -Dhttp.proxyPort=<Port Num> UCDemo
 
Seriously? That's what you're going with? I prefer this tiny ad:
