public class GASHAdmin

extends javax.swing.JApplet

implements java.lang.Runnable, java.awt.event.ActionListener

Ganymede GUI admin console.

GASHAdmin is a dual-mode (applet/application) GUI app for monitoring and controlling the Ganymede server. In addition to monitoring users and tasks on the Ganymede server, the admin console includes a full-functioned schema editor.

GASHAdmin connects to a running GanymedeServer using the admin() method. In order to get logged into the server, GASHAdmin itself publishes an iAdmin object via RMI implementing the Admin interface so that the server can dynamically update us as things happen on the server.
