Help needed in configuring drools guvnor with MySql
by Dinesh kumar
Hi,
I am trying to configure Drools Guvnor with MySql. I am using JBoss 4.0 . I
searched the web and changed my repository.xml that was created in my
JBoss/bin . But I am getting one exception after another and finally I am
struck up in this exception. Any help on this will be of great help..

skip workflow's task from NodeInstance
by dgimenes
I'm trying to do a web page that lists the active workflows
(processInstances) and it's respective tasks that are waiting to be
processed to continue the flow. Also, I'd like to create a button to those
tasks to skip them, and go to the next task.
The first part I've already done with
((RuleFlowProcessInstance)ProcessInstance).getNodeInstances() (and so on),
but now I want to know if it's possible to skip the node with just a
NodeInstance objetct. Can you help me?
thx.
just in case, I'm using the words "node", "activity" and "task" to represent
the same thing.

Drools Rule Engine
by ramram
Hi All,
I am evaluating the rule engine of Drools and I have some questions:
1- Is there a way to make the rule dynamic and by that i mean that the
parameter it takes can vary between 1 instance and another?
2- is there a way to set the parameter in java and pass the parameter set
to the drl file so that it can be evaluated against?
3- concerning the number of users and optimization? is there any benchmark
made and a comparison of how many users and rules the engine can handle?
Regards,
Ram

ClassCastException during inserting knowledge package
by Piotr Jedrychowski
Hello.
I have a problem with such scenario:
1) add one knowledge package (sensor200) with two rules:
package sensor200
rule "Sensor-200-ON"
when
(and f0: FMSensorFact(id==201) f1: FMSensorFact(id==202) )
(not FMFact(id==200))
then
FMFact factToInsert = new FMFact(200);
insert(factToInsert);
end
package sensor200
rule "Sensor-200-OFF"
when
not (and FMSensorFact(id==201) FMSensorFact(id==202) )
(factToRetract : FMFact(id==200))
then
retract(factToRetract);
end
2) remove knowledge package (sensor200)
3) add knowledge package with the same name as in point 1, but with
other rule:
package sensor200
rule "Sensor-200-OR-201-ON"
when
fact: FMSensorFact(id==201)
(not FMFact(id==200))
then
FMFact factToInsert = new FMFact(200);
insert(factToInsert);
end
During adding knowledge package in point 3, I'm getting

Error in OR rule
by Piotr Jedrychowski
Hello.
I have a problem with such a condition after 'when':
(or (and MyFact(id==1) MyFact(id==2)) (or MyFact(id==3) MyFact(id==4)))
For this condition I got this error:
errors; [7,41]: [ERR 101] Line 7:41 no viable alternative at input 'or'
in rule "Sensor-1-ON"[7,64]: [ERR 102] Line 7:64 mismatched input
'MyFact' expecting ')' in rule "Sensor-1-ON"[7,84]: [ERR 102] Line 7:84
mismatched input ')' expecting 'then' in rule "Sensor-1-ON"
When I changed my condition to this:
(or (and MyFact(id==1) MyFact(id==2)) MyFact(id==3) MyFact(id==4))
everything is correct. Both conditions from logic point of view, are the
same, but the first one can't be compiled. Why?
Maybe someone had similar problem and could help me?
I'm using:
* JBoss 4.2.3.GA

How to log defects with its corresponding rule id?
by bbarani
Hi,
I am currently using Guvnor for managing rules. I have a java program which
retrieves the rules information from Guvnor and gives me the validated
output.
I now need to log the defects of each and every record with its
corresponding rule / rule type id in order to know why that / for which
value that particular rule has failed. I am not sure of Guvnor rules data
model as of now.
Can anyone let me know how to identify each rule stored in Guvnor for defect
logging purpose?
Let me know if you need more information.
Thanks,
BB

Error after inserting object in the workingmemory
by Kevin Alonso
Hello,
I´m working with the last successful build(22-may-2010) of drools5.1. I
get the error below, when I try to insert a class instance in the
working memory. This only happens when conditional part of a rule is
satisfied.
I´ve read in previous mails of this mailing list something about this
error and it seems that is related with the call of static method.
http://lists.jboss.org/pipermail/rules-users/2008-January/004485.html
I have a rule that would be activated after the insertion of the
instance. The rule is the following:
rule "ruleA"
ruleflow-group "BlockStageOrder1Round1"
when
State(SizeX : width, SizeY : height)
support : ClassifierPropositionSupport(fDescriptor : frameDescriptor,
fatherClass == "blue", x >= 0 && < (SizeX/4), y >= 0 && < (SizeY/4))
then
ProposeClassifiers.SetClassifier(drools, fDescriptor,"sky");
end
Can you help me solving this?
Thank you in advance,
Kevin.

StatelessKnowledgeSessionImpl.execute does not call dispose() method
by Σάββας Τριανταφύλλου
Hi,
I have noticed that StatelessKnowledgeSessionImpl.execute (5.1.0.M1) methods do not call dispose()
method in contrary to the documentation (http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/ht...)
3.3.7. StatelessKnowledgeSession
The StatelessKnowledgeSession wraps the StatefulKnowledgeSession, instead of extending it. Its main focus is on decision service type scenarios. It avoids the need to call dispose(). Stateless sessions do not support iterative insertions and the method call fireAllRules() from Java code; the act of calling execute() is a single-shot method that will internally instantiate a StatefulKnowledgeSession, add all the user data and execute user commands, call fireAllRules(), and then call dispose().
Is this a bug or has something changed between version 5.0.1 and 5.1.0 ?
