/**
 *   This is an application that will talk to the remote object.
 *   After lookup of remote object, it will query it for a
 *   greeting, which will be shown in the system console.
 *
 *   The reason that this example uses an application and not an applet as client,
 *   is that to get the name of the client we need to have a permission to read the
 *   system properties, something which an applet doesn't have.
