public class AppletServer
extends Webserver

An AppletServer object is a web server that an ObjectImporter communicates with. It makes the objects specified by exportObject() remotely accessible from applets. If the classes of the exported objects are requested by the client-side JVM, this web server sends proxy classes for the requested classes.
