Find the "Java Console" and open it. It will most likely contain an
explanatory error message. Most likely it's simply a security
exception; IE isn't letting Jess read something or other that it wants
to read (the .clp file, for instance, or perhaps
jess/scriptlib.clp. Hairy, complicated, constantly changing, and
largely inscrutable security rules are one reason why you'll not
encounter many unsigned applets on the web these days consisting of
more than a few dozen lines of code.

Of course, you don't want to convert the graphical console class into
a Servlet, since servlets don't have GUIs; you want to simply make
Jess method calls from the body of a normal servlet. Eventually I hope
to provide an example servlet. For now, suffice it to says that once
you've learned about servlet programming, and studied the examples in
the Jess manual on embedding Jess in Java applications, you should
have no problem writing such things from scratch.

I've used New Atlanta's ServletExec with IIS, which is very nice (but
only the crippled demo is free.) The other things I've done servlets
with have involved using other web servers (Sun's Java Web Server,
Apache + Apache_jmod, the W3C's Jigsaw which has native servlet
support.) Of all of these, Jigsaw is my favorite. JWS was my least
favorite.
