JESS: So lame, and so sorry - disregard last post
Hi again, Just worked out my own answer. I just needed to add a defclass line to my clp file, so it knew about the class! (defclass newAddress Address) ;; new line of code (defrule complete-address (newAddress (locality ~nil) (number ~nil) (postCode ~nil) (state ~nil) (streetName ~nil) ) = (printout t launching crlf) ) Sorry, it always seems like I work it out after posting, even though I really think before posting. :-( I guess I answered my first question from a Jess user though! So it's not a complete waste, is the following line still the reccomended way of loading rules from Java? engine.executeCommand((batch jess_test.clp)); Ta, Matt -- Matthew HutchinsonPh.D. CandidateDepartment of Spatial SciencesCurtin University of TechnologyGPO Box U1987Perth, Western Australia 6845
JESS: Loading rules from file that relate to javabeans
G'day everyone,
I'm looking to create a java object, and monitor this via its javabeans
compatibility. Then if the object's properties meet certain criteria,
then a rule fires. I have done this with no problems using the Jess
command line, but am now interested in doing the equivalent via the
Jess API.
I understand how to do this, but have a queston regarding the storing
of rules. I want to store my rules in a .clp file, which if using the
Jess command line, i would just use (batch).
How do I create the bean complient object in Java, but ensure the rules in the .clp file know what I'm referring to?
my code for a simple java class is:
-
import jess.*;
public class JessDemo {
public static void main(String[] args) {
Rete engine = new Rete();
try
{
engine.clear();
engine.executeCommand((batch jess_test.clp)); //this line causes an
error
engine.defclass(address, Address, null);
Address
inputAddress = new Address(null, null, null, null, 36,marlow,
street, wembley, wa, 6014);
System.out.println(inputAddress.toString() );
engine.definstance(address, inputAddress, false);
}
catch (JessException error)
{
System.out.println(Error!);
System.out.println(error.toString() );
}
}
}
--
the clp file to be used with the javabean contains:
--
(defrule complete-address (newAddress (locality ~nil) (number ~nil)
(postCode ~nil) (state ~nil) (streetName ~nil) ) = (printout t
thunderbirds are go crlf) )
any my original clp file, which i used at the jess command line, was:
(clear)
(defclass newAddress Address)
(ppdeftemplate newAddress)
(bind ?na (new Address nil nil nil nil 36 marlow street wembley wa 6014 ))
(definstance newAddress ?na static)
(reset)
(defrule complete-address (newAddress (locality ~nil) (number ~nil)
(postCode ~nil) (state ~nil) (streetName ~nil) ) = (printout t
thunderbirds are go crlf) )
obviously I typed (run), too. it worked no problems.
I know enough that because I have removed the defclass, ppdeftemplate,
bind and definstance commands from the top clp file, the rule has no
idea about what's going on...
so in a nutshell: how do you store rules in a clp file about an object that is not yet instantiated?
Cheers,
Matt

In Jess 7, there's a Rete.batch() method you can use instead;
otherwise, what you've shown works fine. Another alternative is
Reader data = ... // Open file, or whatever
try {
Jesp jesp = new Jesp(data, engine);
jesp.parse(false);
} finally {
data.close();
}

Protege questions tend not to get answered on this list. You should try asking this on a Protege mailing list or forum. - Ernest Friedman-Hill Advanced Software Research Phone: (925) 294-2154 Sandia National LabsFAX: (925) 294-2234 PO Box 969, MS 9012 [EMAIL PROTECTED] Livermore, CA 94550 http://herzberg.ca.sandia.gov To unsubscribe, send the words 'unsubscribe jess-users [EMAIL PROTECTED]' in the BODY of a message to [EMAIL PROTECTED], NOT to the list (use your own address!)

Re: JESS: For-loop bug
You're right -- that's not the correct behavior. Thanks for the report. I think Yura wrote: [Charset koi8-r unsupported, filtering to ASCII...] Hi I think there is a bug in the 'for'-loop implementation. The following code returns '1' (incorrect): (bind ?x 1) (for (bind ?i 1) ( ?i 2) (++ ?i) (bind ?x (float ?x)) (printout t ?x == ?x crlf) ) ?x When I comment out the 'for'-block the expression evaluates to '1.0' (correct).

Re: JESS: New to JESS
Hi, having just started using Eclipse myself, I would suggest: - making sure you unzipped all the correct plugins into the correct directory - make sure you create a new *java* project in eclipse, not any other type cheers, Matt On 10/10/05, nikita berdikov [EMAIL PROTECTED] wrote: Hello, I'm new to Eclipse and JESS, so can anyone tell me how to start working with JESS in Eclipse 3.1.
