Hi,
I recently run into some problems when trying to create a simple holiday
request process.
I defined process variables but I struggle to understand how to access them
in Human Task.
In my User Task ,,holiday approval I have this as a description:
#{employee} requested holiday for #{length}
Hello everyone.
I've got a question regarding the performance of Drools in STREAM mode.
It seems to me, that either Drools is not very fast here, or the problem
is with the rule itself.
This is the rule.
rule ABC
no-loop
when
$a :
You need to use both mappings
IN Mappings (Parameter Mapping in the IDE): this will copy your process
variables to the work item scope
and OUT Mappings (Result Mappings): this will copy the information created
or modified by the work item (in this case a human task) to the process
scope.
yes I'm with Rui,
Changing the annotations in the code requires recompilation.. and that's not
good... because when you update your drools version (ramram) you will lose
that kind of changes.
I think that the best solution is to create xml mappings for different
vendors.. Rui if you can contribute
I'm using Drools for a system of alarms on agriculture. I am considering
several parcels, whose plants can be on different status (for example,
sprouting, flowering, etc.). These statuses are updated automatically by
rules, controled by several calendars. In the other hand, the farmer is

What and how are you timing?
Executing exactly this rule on three event types with just an int id,
running with
long t0 = System.currentTimeMillis();
int count = 50;
for( int i = 1; i count; i++ ){
session.insert( new EventA( i ) );
session.insert( new
For you, maybe t1 is more important than t2, but for someone else perhaps t2
is more important than t1. I don't know which solution is better, but right
now, t1 is being logged and t2 is being thrown.
Here is the Jira issue: https://jira.jboss.org/browse/JBRULES-2656

Hi!
I created a new issue some days ago. I'm new to the jboss community and
therefore not sure whether I did it correctly. It seems like no one has
found it yet.
Could somebody have a look at it and could provide me feedback?
http://jira.jboss.org/browse/JBRULES-2782
The system is receiving readings from real sensors of humidity, temperature,
etc.. There are a lot of rules for deciding if a specific plague or illness
affects (or can affect) to the plants or not: One condition of those rules
is the plants' status, because the illnesses affect to the plant

I think that a parcel (a field) needs to be a static fact, perhaps not
maintaining a single state but two states, previous and current. Events are
state changes and sensor readings.
Now, if sensor readings are dangerous for state A and if the last state
change is not much distant from the sensor
Well, I'm in a dead end with my model, so I'm going to consider your idea. I
think it is best solution.
Thanks again.

Do you mean that insert (send) Y times A inserts Y times Aevent with the
very same id?!
If so, you will have to reconsider your approach because you are creating
the worst possible scenario for the Rete algorithm, i.e., O(n^3) cartesian
tuples for your activations.
There are strategies for
After some research it seems that jackrabbit handles the
serialization/deserialization of the rules.
However, I cannot find how the rules are exported so nicely (with a nice XML
structure, with lhs, rhs tags). If I use XStream to serialize a

Hello again!
Thanks for the heads up, Wolfgang.
Basically, what I try to create is some sort of batch window, which is
not really implemented into Drools Fusion if I remember correctly.
It doesn't HAVE to be A, B, C in that particular order which I specified
in my last post, but the
Hi Leonardo,
Thank you very much for your fast response!
I mentioned why I re-added the same rules within the issue-description.
It is something like a simulation of lots of rule changes. We are
building an application where rules will be created programmatically.
Rules will often change.
For
And, I hope, it doesn't matter in which order the Events A with id x are
matched with Events B with the same id.
The idea of my approach is to make the Events A, B, C not directly visible
to the rule ABC but through a filter fact, one per type (A, B. C) and per
id.
Here is the abstract base

Hi All,
I am able to print the logs that says which rule was fired and what is the
id for it.Thanks Wolfgang!
Is there any way I can print the conditions(when clause) that got executed
and which condition failed to execute and the order of those conditions
execution?

Hi Geoffrey.
Thank you very much for your replies. I was just testing the Drools Planner,
and the way it was implemented (with a search approach), I thought it would
work with the 8Puzzle problem. I already worked with this problem executing

When I asked this question, I meant I don't want to use any frameworks
or application servers. But for now I think I should consider to use
jBoss or such to manage cross session tx.
I'll take look at this Spring's implementation, because I think there
should be an independent implementation in
