All Implemented Interfaces:

java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable, javax.accessibility.Accessible

public class LogApplet
extends java.applet.Applet

This Applet reads the applet parameters, concats them to one string and sends it to the scone Remote Access Server. The Applet gets the destination for the socket connection from parameters.
Everytime the method logMsg is called by javascript, a corrisponding string is sent to RAS.
Transmissions of the RAS can execute JavaScript commands
