If your organization has a firewall to protect its network from
access by users outside that network then you will need to configure
the applet viewer to access applets outside your network.

To set up the applet viewer to connect through a proxy gateway to the
Internet:

1.Bring up the applet menu by clicking on the 'Applet' item at the
  top left of the menu bar of the applet viewer.
2.Click on 'Properties'.
3.Fill in the http proxy fields.

  E.g.
  Http proxy server: myproxy.mycompany.com
  Http proxy port:   80
  Firewall proxy server:
  Firewall proxy port:

  If your Web Browser is already configured to connect to the
  Internet use the values set up there.  (e.g.  with WebExplorer use
  the Proxy Gateway values in the Configure-Servers page, omitting
  the leading 'http://' and trailing '/'.)

  If you do not know your Proxy Gateway consult your system
  administrator to see if you are authorized to use the proxy
  services.

4.Click on 'apply' to store the changes.
5.Close the applet viewer.
