Guvnor-5.5
by Ricardo
Is any one tried guvnor-5.5 in websphere application server?
What happen to the conponents.xml?
Why guvnor is tightly coupled with jbossAS even each version (jbossAS) got
separate war file?
this seems a big impediment for using guvnor as rule authoring tools.
Is one knows well aware these and already know how to deal this, please
advise me?

with kind regards,

[Drools Planner] Multi depot CVRP / CVRPTW
by Mats Norén
Hi,
I've been looking at the VRP example in Drools and I'm thinking about using
it for multi depot cvrp and / or capacitated vrp with time windows.
Has anyone else tried planner for these use cases and can maybe shed some
light on their implementation?
Regards,
Mats

"Rule-Id" for a Drools Rule
by harishtejwani
All:
We are using Drools to detect specific events/conditions in our system.
In the 'then' condition of Drools rule, we would like to persist the "Rule
Id" of the rule that created the specific event/condition
This is because all our reporting is based on "rules" as filters, where
users can look at exceptions by specific rules.
Is there a suggestion or sample as how can the "Rule Id" be persisted or
indicated in the then condition that is immutable or can be long-lived. The
current approach of using Rule Name itself as the ID is brittle as this can
be changed and suddenly all reports would break.
If we assign ID's to rules, where do we keep the mapping of RULE ID to
Rules. If we store rules in GUVRNOR is there a way we can get Rule Id's for
Rules?
Best regards
Harish Tejwani

successfully deployed Guvnor in Tomcat.In next step I have created a package
then add a new category and added a rule with Decision Table (web - guided
rule ) as a rule formate.I was able to create a rule with certain set of
conditions and actions.On clicking Include Advance Option and choose *Add a
condition BRL fragment* or *Add an action BRL fragment*, I am getting java
script error and nothing is moving forword after that. That mean I am not
able to add and BRL fragment to my rule.
Can any one help me for this. Does I am doing any thing wrong.

How can I select planning-entities in the accumulate source-pattern based on a list of planning-variables?
by Michiel Vermandel
Hi,
I am kind of stuck in writing a rule :
I have PeopleMatch facts in working memory.
Each PeopleMatch has a number of persons: PeopleMatch().getPeople = List<Person>
I have planning-entities (Tasks) which have a planning-variable Person.
Now I would like to create a rule to loop over the PeopleMatch objects, gather all Tasks for the people of this match and do some calculation with all tasks.
This is what I have for the moment:
rule "matchPeopleTasks"
when
$match : PeopleMatch()
$people : List() from $match .people
$match: Number( intValue < 0 )
from accumulate( $task : Task(handler == $people),
init( Matcher matcher = $match.getMatcher()),
action( matcher.addTask( $task ); ),
reverse( matcher.removeTask( $task ); ),
result( matcher.getMatch() ) );
then
...
end
The problem area is of course the "accumulate( $task : ProjectTask(handler == $people),"
How do I select all tasks in the accumulate function, based on a list of people?
Thanks,
Michiel
