Hi,
I apologize for barging in. I'm just guessing that John might be using
Jess in combination with Protégé
(object (is-a Node\ Spoof) (resource\ sequence $? ?o $?) (Behavior\
ID ?bid))
looks very much like a mapped instance with JessTab. Asserting facts
with mapclass or mapinstance creates facts that have
this "object/is-a" thing
Usually this shouldn't interfere with the efficiency and possibilities
of using Jess.

This should work fine if the "resource sequence" multislot contains
the actual fact object; if you showed us where you assert the "Hello"
fact, then I could probably tell you what's gone wrong.
While we're here, I should ask why you're doing this "object/is-a"
thing, rather than having a "hello" template and a "node spoof"
template; you're doing a lot of extra work to make sure Jess can't
work very efficiently. And I can tell you that the "and" is not needed
here; all the patterns on the LHS of a rule are implicitly "and"-ed
together. And finally, my goodness, you're going to drive yourself
nuts embedding spaces into symbols like this -- don't do that!

Hi all,
I am a rookie to jess. I was stuck-up with this problem for the past
24-hrs.
So kindly advice.
I created two classes with multislots. The second class has a
multislot of
type - instance of the previous class. I am not able to pattern match
the
instance in the second class's object. Multislot pattern works well
for
strings. How can i do it for multislot of instances? I have attached
the
snippet for your kind perusal. Please Help.
(defrule testnest
(and
?o<- (object (is-a Hello) (Neighbor\ Address $? "10.0.0.1" $?)
(Resource\ ID
?rid))
?r2 <- (object (is-a Node\ Spoof) (resource\ sequence $? ?o $?)
(Behavior\
ID ?bid))
=>
(printout t "Attack" crlf))
The Two Classes: Hello and Node Spoof
Multifield slots : Neighbor Address (type STRING) and resource
sequence
(is-a Hello)
Thanx in Advance
