Hi,
I am implementing rules engine into my project, I have been referring the many
technical resources about jboss drools.
I did implement some set of rules which are much more needed for my project.
All of a sudden after I placed all the rules in the spreadsheet(.xls) file, and
executed it,

hi,

$p: RuleContext($size: getOldContext().getParent().getUsableSpace()

then
Event event = new Event(folder almost full,
$p.getOldContext().getParent(), new Date());
event.display();

Assuming Event has a field called context (which is set by the
constructor you use in your RHS):-

$p: RuleContext($size: getOldContext().getParent().getUsableSpace()
(30*1024*1024))
* not Event( context == $p.getOldContext().getParent());*
then

What field do you set in the constructor then?
new Event(folder almost full,* $p.getOldContext().getParent()*, new
Date());
Whatever field this is you should check in the LHS with the not
Event() - this ensures the rule only activates if there isn't an Event
already for the RuleContext.

yeah.. i understood what u meant.. i tried it.. but still problem is not

Above all, realize that only facts *insert*-ed into Working Memory can
be taken into account by rules. So, first thing, insert the Event in rule
size. Then you can, basically, write a rule like this:
rule size
when
$p: RuleContext($size: getOldContext().getParent().getUsableSpace()
Can you please elaborate about why do you want to do that? what's the point
of having a list inside of the Event class that will contain the same event?
The Then side of the rule is pure java.. so you just do
event.getEvents().add(event);
but I don't see the point of doing that.

Actually, il have to use this ListEvent in another class and then print
listEvent after every rule execution cycle.

Seeing that the list is static you can use the usual way for accessing
a static class member:
Event.listOfEvent.add( ... );
@Mauricio: It's not unusual to maintain a static collection (even
though there may be better ways, esp. with Drools).

Hello every body !
I'm a new drools Fusion user, And I'm now facing a real problem which
is that my events attriutes values doesn't go to starttimestam and
endtimestamp, I explain :
when declaring a new event
declare Evenement
@role(event)
@startimestamp(attr1)
@endtimestamp(attr2)
If you look at the implementation of EventFactHandle.getEndTimestamp
(not ...eSt...) you'll see why: it returns startTimestamp + duration.
You should *not* use methods that aren't in the stable part of the Drools API.
Also, the documentation does not tell you that you can map event
attributes

According to the documentation:
Rule constraints do not have direct access to variables defined inside the
process.
It is however possible to refer to the current process instance inside a
rule constraint,
by adding the process instance to the Working Memory and matching for the
process
I had some tests working fine in jbpm 5.1 but failing in 5.3 because of
this same reason. I'm not sure if this is this is a regression bug or if
there is a deliberated change in the behavior.
Maybe someone in the jbpm dev team can shed some light here.
Best Regards,
We're using 5.2.0 final here.
What we are also observing is that whenever a process instance reaches a
businessruletask node the rule gets fired a number of times equal to the
number of instantiated processes even if any of those processes didn't
reach the bussinessruletask node.
Does this means
The behavior you described is how it is working in 5.3 (and it seems 5.2
too). The rule is fired once per process instance you have in your working
memory no matter if the others instances are, are not yet or even has
already been in that Rule Task Node. Again, I'm not sure if this is a

OK, let's step back a bit.
What are you trying to achieve?
Do you *want* the DRL text, or do you want to load a BRL rule?
Where did you get the BRL rule from, normally rules are authored in DRL (in
which case you'd use KnowledgeBuilder, as in all the examples) or in Guvnor

Support for the BRL editor in Eclipse was dropped as from 5.2.0, so I assume
