Hi, all:

I have three questions:
1. It seems that Applet demo
http://herzberg1.ca.sandia.gov/jess/demo.html
doesn't work on my sun sparc solaris workstation with Netscape 4.51. The
error is: netscape.security.AppletSecurityException: security.class from
local disk trying to access url:
http://herzberg1.ca.sandia.gov/jess/examples/sticks.clp
Does anybody know how to make it run or how to solve the security
problem?

2. Can I use only java JDK 1.1.x and Jess50ax but without servlet to
make Jess on the server side, GUI runs on the client side? I got this
error when I tested my program on the netscape brower 4.51:
netscape.security.AppletSecurityException: security.member access.

3. Jess system command pipes output to console since Jess50a5. It can
run (system "ls"), but it seems to run (system "ls -l") will give error
like:
Nested exception is:
java.io.IOException: ls -l: not found.


Thanks for any replies in advance!
