Unfortunately the suggested solutions does not work. I have both 
versions on the server:

https://files.nyu.edu/emf202/public/jv/NatalTransitsA.html

uses the jar archive, while

https://files.nyu.edu/emf202/public/jv/NatalTransits.html

uses the transits folder.

Both work fine in my browser when running from the local files, but when 
running through the Internet they both give a 
java.security.AccessControlException, after using

catch (e Exception)

The code is here

https://files.nyu.edu/emf202/public/jv/NatalTransitsApplet.java

What is done is similar cases?
