The applet below, which can also run as an application, works
with the application SimServer,
which must be started separately as an application. See the previous
page : Client for Experiment Simulation
for a discussion of the applet's code.
Note that this applet will generate
a security exception when it attempts to open a socket
to the SimServer unless the machine
from which it is downloaded happens to be running the server.
(Also, the host address would need to be changed to the address
of the host from which the applet was downloaded.)
For your own experimentation, you should download the files for
both the client and server to your machine. Then compile and run
them locally. You can use the host address 127.0.0.1
to point to the local server.
