JESS: Re: [s] Help Jess C#
Pls i need help on this, im trying do developd a study, about the the implementation of JESS in C#.net, i think the only way possible is converting JESS in XML and then convert XML to Rule engine suported by C#.net dont kwon if this is possible help me if anyone can pls, the finish of my graduation depend on this -- View this message in context: http://www.nabble.com/Help-Jess-C--tf3265887.html#a9267148 Sent from the Jess mailing list archive at Nabble.com.

I don't know how implementation of Jess in C#.net, use Jess in C#.net, and converting JESS in XML and then convert XML to Rule engine suported by C#.net, could all mean the same thing to you. I guess you're using that odious IT manager definition of implement, defining it to mean something like use. But in any case, you might consider using Jess as a rule server, as described in chapter 21 of Jess in Action. Wrap Jess in a simple, dozen-line server process which accepts Jess code and returns results just using the Rete.eval() method. You could make it a SOAP server to make it simple to talk to from C#. For the last one, you might want to make a cup of tea, sit down, and have a good look at the Jess 7 manual, which describes Jess's support for an XML rule language. - 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://www.jessrules.com 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: Working with Exceptions

I mean like (defrule someRule comment (Callhome (thing1 ?a)(thing2 ?b)) (try ( ?a ?b)catch (printout t they need to be integers crlf)) (test(eq ?b TRUE)) = (printout t done crlf) ) in the above case the engine throws me an exception when ?a and ?b happen to be strings and then it doesnt fire the remaining rules. i dont want that. Instead i would want the engine to just ignore this rule if ?a ?b are strings. can this be done.? You'd have to put that try statement into a test conditional element, just like any other function call that's outside a pattern. Just make sure you return FALSE from the catch block, and it will halt pattern matching. Just something like (test (try ( ?a ?b) catch (printout t they need to be integers crlf) FALSE)) ought to work fine. - 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://www.jessrules.com 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!)

JESS: Commenting JESS files
Greetings! Is there any way to do Java style commenting in JESS files? Like anything after /* and before */ is ignored by the loader? It would sure make coding a lot easier than having to put a ; at the beginning of every line.

JESS: removing modules
In our application, we are dynamically creating and removing rules from the engine. We are sent a set of rules that are associated with a certain module based on parameters passed to us along with the rules. We are notified when a rule is no longer needed and we remove the rule (or rules) from the engine. What we would like to do is when a module no longer contains rules; we want to remove that module from the engine. I've searched through the documentation/book/api but did not see a way to remove a module from the engine. I noticed in the mailing list that someone retrieved an iterator of modules and removed a particular one from the iterator using iterator.remove(). Is this the best way of removing modules or is there a more efficient way to accomplish this? Also, is there a simple way to determine if a module contains any rules? Thanks for any assistance. Scott
Re: JESS: Commenting JESS files
Good news! Thanks. I just looked in the JESS in Action book and its not there. I didn't think to try the online version. But I will double check things next time. I tend to be a little lazy with online version since there is no index as there is with the book. Guess I am a little old fashioned that way.
