It's probably what one would, in polite circles, call a hack but it does work...

The function docs for (batch) (in chapter8 of the manual) say that the-------------------------------------------------------------------------------

the file hanging off of the applet's documentBase. No place does the
manual say that batch takes a URL; if this works in an applet, it's
just undefined behavior -- a coincidence.
If you want to load Jess code from a URL, then the only legal way to
do it is to do it yourself. This is pretty easy -- something like
Rete engine = ...;
URL url = new URL("http://foo");
Reader r = new InputStreamReader(url.openStream());
Jesp j = new Jesp(r, engine);
// Read until end-of-file
Value v = j.parse(false);
would work fine. This is all that (batch) does.
