First of all, the only chance of this ever working(if any), is if you run the
browser on the same machine that has the Webserver and applet. Since you
use localhost, that will always refer to the local m/c. If this is indeed
the way
you have it, then you may need to check to see that the machine has
connection
permissions set to listen,accept..
