Hi,
I want to fire a session with fireUntilHalt()
and make other threads insert facts in that session.
Is drools rule engine thread-safe in that sense?
If not, what else can I do?
Thanks.

No doubt I'm missing the point but have you seen "3.3.7.1. Sequential Mode"
in Expert's documentation?

As I understand the Expert documentation, Sequential Mode has to be
turned on, even with a Stateless Knowledge Session to achieve all the

Hi again,
maybe I should specify what exactly I want to do.
I'm developing a project in a team. We're using the eclipse IDE.
I would like to configure maven the way that it builds the eclipse
project, downloads the drools library and adds the drools library to the
projects build path.

Hello,
I am currently working with Drools Decision tables, and have created a
decision table to determine availability of offers.
I have Offer Entities which contain a collection of "groups" that the offer
can belong to. That collection contains strings of ids that identify those
groups.
Hi,
I would like to install drools for one of my projects using maven. (I've
already ask the maven mailinglist. They said I shall ask here, because
it's Drools related.)
I've set up the repository and the drools reference in my projects POM file.

I think that a single helper class
class Marker {
String property;
Object target;
}
would be sufficient:
// 1st consequence
insert( new Tag( "London", customer ) );
// 2nd condition
Tag( property == "London", $target : target )
Customer( this == $target, job == "teache
You aren't using the conditions "within one hour" here, but other than this,
it should work well, even with the customer identity included.

With two ProcessResult objects, this

There is something in 5.x which allow a rule to inherit from
another. Inheritance is on parent rule conditions.
May be you could write something like this:
rule "london_guys"
when
customer:Customer(town=="London")
then
its working...i added one global variable in the session and i was trying to
access other which was not in the memory.

The consequence section of a rule (i.e. right hand side) is simply a block
of code (in whichever dialect you're using).
Can you elaborate on what is not working? Your code looks perfectly good

Hi Folks
I've been playing with Guvnor and have been defining Test Scenarios. Mostly
the scenarios meet our requirements for simple rule packages. However we use
small flows which only use rule tasks.
I've seen that the ruleflow-group support works however I'm wondering if a
test scenario can be
AvailabilityRuleState s = new AvailabilityRuleState();
s.setValue("Not Available");
s.setReason("Type Specific");
s.setReference("Availability rule FrontAxle and
FrontSuspension Type");
resultState.add
What do you guys think of this: my facts are all the same type, so I didn't
have anything like a consumer object to break things down with. But what I
did was:

when

not Trans( this != $a, prodCat == $groupValue, date < $date )
Hi Leonardo,
the performance problem I thought of meant removing and inserting the facts

and execute the second rule only on the remaining facts.

I didn't think the Engine would go back to the Eclipse Compiler if JANINO is

So I always thought he was only looking for the Eclipse Compiler.
I added JANINO to the Classpath in it worked like a Charm.

I've found that you can use insert and possibly update in action nodes with
mvel. It seems so far that the properties of inserted objects are then
accesible in rule nodes (for example a split node). However I was suprised
to find out that it did not work if the asserted object is in a member

Checks for all activations but that is probably more correct as another rule

it turns out that inputSource memberOf $rule.inputTableList is the problem.

Thanks for your prompt reply.
Even if i remove those extra conditions it still takes a lot of time given
the fact that i have only 2 facts.
my getValue() maintains a hashmap and it returns values from the map. So it
should be fast. I tried removing equalsIgnoreCase and its still the same.
Any takers on my question below... Or have I answered my own question?
