Hey Luciano, Meanwhile i tries pumping in the rule with a webdav api
(Sardine in my case) and that seems to work and trigger ok for me. this is
how i did that
public class SardineTest {
public static void main(String[] args) throws SardineException {
Sardine sardine = SardineFactory.begin("admin"
Hello,
I've been making myself familiar with Drools Planner and in the process
of doing so, I've hacked together a simple algorithm for optimizing the
Travelling Salesman Problem:

At this point, I get a 7 % improvement over a route with 71 stops, which

You might be disabling "delta score calculation" with your score rules:

Sample code from it to add rules in a drl file.:

The suggestion of placing the type declarations in the template worked.
However I am eager to find a solution where they can be defined
independently without exhibiting the bug mentioned earlier in the thread?
Thanks,
James

As far as I know, Drools can only reason over facts in the working memory. It
can not directly "select" from RDBMS. You have to load in all data items
from the database and validate them in memory by Drools.

I’d potentially be interested depending on what time it is – during the day
would actually be better as I could probably get away with it being classed as
training for work.

Hi.
I have such declaration of type
declare Contact
firstName : String
end
then I want to add new property to this type. so the next version is
declare Contact
firstName : String
newField : String
end
this type declaration is in separate drl file.
then I add this new type to current Knowl
Did you try using
ResourceFactory.newFileResource("C:\\savedRules\\rule.drl")? A FileResource
is more appropriated for your case I think.
By the way, this kind of questions should go in rules-users@lists.jboss.org.
I'm forwarding it now.
Best,

You can access Objects from external resources using the "from" keyword (in
fact the use of this with Hibernate named queries is a documented use-case,
IIRC).
The Objects are not however inserted into WorkingMemory using "from" are
should therefore be time-constant as their properties will not be
Beware with the use of the FROM Conditional Element, because if you are
using another fact that doesn't come from the DB and you change them, the
FROM CE will be continuously evaluated causing the execution of tons of
queries multiple times.
My two cents.

Great, but i like (need really) to triger the rules from a web
service, since i am outside the JVM, i will use the web interface to
manage the rules, at least at the beginning.

Sure, I agree, this would be an example:-
rule "Family smurf"
when
MyFact( smurf == "pupa" )
ExternalObject( ) from placeHolder.namedQuery("Smurfs")
then
//Do something
end
If MyFact is updated in other rules the list will be refreshed "from" the
named query.
So the preference might
Are you adding rules one by one? Or are you adding files that contains
multiple rules?
If you are adding rules one by one you could try something like this:
1. create a kbase
2. for each rule:
1. create a kbuilder
2. add the rule to the kbuilder
3. add the generated packag
Template expansion is just text processing. Inserting some text into a
template before expanding the modified template should be simple. And even
an insertion after expansion is feasible for some of the expansion
procedures.

The current version of Drools does not support dynamic changes in "type
declarations" and I don't see this changing anytime soon. The reason is that
not only the actual fact would require changes, but the actual knowledge
base would require changes as several nodes might be referencing the old

I am using Drools 5.1.1. The error occurs when I am pointing at the .drl
file too.
The scanner says (after the error) that it is scanning 0 resources
And what will happen to any FactType objects out there? Or the Class
objects derived from them? Will it be safe to continue to use the object
returned by KnowledgeAgent.getKnowledgeBase() which is documented to return
a "cached KnowledgeBase"?
Whoa!
