Hello Thomas.

Sorry to hear your having problems with getting the applet going:

This is generated by the applet launcher trying to retrieve the java 
classes directory, after failing to retrieve the archive at the given path.

Your applet tag looks fine. I think there may be a problem with the 
configuration of your web server, meaning the cgi-bin directory is not 
actually served externally. Remember, the archive parameter has to 
resolve to a URL that the browser can use to retrieve the 
jalviewApplet.jar archive, and 
http://bisc.cse.ucsc.edu/cgi-bin/jalviewApplet.jar does not work.

There is actually no reason to put jalviewApplet.jar in the cgi-bin 
directory, since it is a client side resource. Try changing the archive 
parameter to "jalviewApplet.jar", and copy the jalviewApplet.jar file to 
the same directory on the web server as your testjview.html page.

hope this helps!
Jim
