This example demonstrates the use of a Glacier2 router and the
implementation of a Glacier2 session server.

To run the demo:

Start the server:

$ java Server

In a separate window, start the session server:

$ java SessionServer

In a separate window, start the Glacier2 router:

$ glacier2router --Ice.Config=config.glacier2

In a separate window, start the client:

$ java Client

If you plan to run this demo using clients on different hosts than
the router, you must first modify the configuration. You need to
change the Glacier2.Client.Endpoints property in config.glacier2 and
the Ice.Default.Router and Callback.Client.Router properties in
config.client. In all cases you must replace the "-h 127.0.0.1"
parameter with the actual external address of the machine on which
glacier2router is running.
