Visigenic Applet

README

To run VisiClient applet, you need to do the following.

Start osagent and gatekeeper (with port 16000)
(for gate keeper, create a file called gatekeeper.properties and just
put this entry in there : exterior_port=16000)

Then start the Bank server (vbj Server &).

Your browser should have Jinitiator installed (use ojdk-pc.us.oracle.com
for getting JInitiator, jdk 1.1.7.18)
(Browser security doesn't have to be off, i.e, you may set it to
AppletHost in Jinitiator)

Then simply connect to  mysun:8080/applets/bank/VisiClient.html
