Why not use from? The manual suggest this approach to reason over data that
is not explicitly asserted in knowledge base. It seems to me that it fits
best in the requirement of Laird. Please correct me if this is bad practice:

Hello All,
Drools 5.1.M1 is bundled with a JBoss 4.2.3 GA in download section,
ok I red http://community.jboss.org/wiki/DroolsGuvnor50inJBossAS5 info but
just wanted to get on the safe side:
Has it been tested/validated to get Drools 5.1.M1(Guvnor) to be used and
deployed over a JBoss
I tried looking for one but couldn't see one in the PipelineFactory that can be
used when I've received an object from the jms queue. I'm hoping that I'm just
being blind or something...

Hello,
we are using Drools in our company. We have a rule with three conditions in
this format:
when
Condition A
Condition B
Condition C
then
execute Action 1
Now we have a situation, in which the rule should fire if AT LEAST two of
the three conditions are satisfied. Do
Ah, that was next in my list of technologies to look at anyway so I guess I'll
just look at camel and forget about the pipeline stuff.
Are there any good starting points/examples that are worth studying?
Thanks,
Thomas

If I were you, I'd use something like
Global java.lang.Integer cnt;
Rule before everything
Salience 10
When
Eval(true)
Then
Cnt=0
End
Rule condition A
When
condition A
Then
cnt=cnt+1;
End
Rule condition B
When
condition B
Then
cnt=cnt+1;
End
Rule condition C
When
condition B
Then
IMO you can just use activation groups and not have to deal with
incrementing, something like:
rule first
activation-group myactgrp
when
Condition A
Condition B
then
...
end
rule second
activation-group myactgrp
when
Condition A
Condition C
then
...
end
rule third
Yes, you're right Tihomir Surdilovic
your solution is way more elegant than mine.
And to skasab2s: you should use a function to avoid copy and paste three time
the same then clause

Hi,
I know this is repeated again but I tried the solution mentioned in the
previous posts and it doesn't work.
When I created a guided rule in eclipse, I get blank dropdowns when choosing
the facts.
I added the jar file for the classes as an external reference
I also added a .package file to
This will not work. Rules will not predictably react to changes in global
variables. Use an object in working memory.

For simple constraints like this, using nested accessors is lighter and
simpler than using from.

Phrases like this should go in a drools best practice sections :-) Does
something like that exist?
When you read the docs, you get the impression that from is the
I had to do something like this. The way I did it is by prividing a
method in my object in working memory that takes multiple Boolean
conditions and loops through them and return true if at least N of the
conditions were true. So, this funtions will take N and a list of all
conditions.
Hi,
I have a rule with the condition that looks like below:
when
item : Item()
list : ArrayList(size 0) from collect ( SubItem( type == X ) from
item.getSubItemList())
When I execute this rule, it seems to me that the order of elements in the
collected list is not the same as they
Hi,
I am getting the following error when I try to do complex object referencing in
drools:
My class:
A{
String Type;
B objectb;
//getters and setters for above
}
My rules:
rule prod
when
$a :A(Type == Prod , objectB != )
then
B bobject = new B();
bobject.setType( Prod
Hi,
I’m new to drools, just started evaluating Drools-Guvnor for a project. To
take advantage of Java-enums I’m using the current 5.1.0 Milestone 2.
I created a decision table (web-guided) in drools-guvnor and deployed the
package snapshot, which is downloadable and returns a .pkg-File. This
You can't modify bobject, becuase it doesn't exist inside the session. You
just created it a few lines above. Maybe you need an insert() or maybe you
need the bobject reference from the LHS. Something like this:
*rule* prod
*when*
$a :A(Type == Prod , objectB != )
*then*
Indeed, the change set is an xml file specifying the resources to
add/modify/remove. Take a look at the change set structure here:
