Foil 87 Control Applet

From Tutorial on Java for Middle tier in Computing Portals Tutorials at ACM Java Grande Meeting -- June 14 99. by Tom Haupt


1 The control applet is responsible for maintaining the session, and direct communication with the middle-tier.
2 Direct communication is the most efficient, but since it is buried into an applet, this mechanism is not readily customizable.
3 The generic services, such as file service (upload, download, edit, copy, move, delete) and job services (show current jobs/show queues/kill jobs) will be supported this way. [combination of the user context and a query]
4 The Gateway will also support a non-direct communication with the middle-tier through servelts.
