Re: [rules-users] Help write rule drools

[Wolfgang Laun]

To remove all redundant Link objects and assuming that class Link is declared as
   class Link {
 Node source;
 Node target;
   }
(and not as given in the original post), the rule:

rule "kill redundant links"
when
$l1: Link( $s: source, $t: target )
$l2: Link( this != $l1,
   source == $s && target == $t
   ||
   source == $t && target == $s )
$n1: Node( out contains $l2 )
$n2: Node( in contains $l2 )
then
retract( $l2 );
modify( $n1 ){ getOut().remove( $l2 ) }
modify( $n2 ){ getIn().remove( $l2 ) }
end

removes all redundant Link facts and updates the out and in fields of
the Nodes at either end of these links.

I try to explain. I have a graph where each node can have only one connection
to the other. 
If I check the presence of n links between two nodes then delete n-1
connections.

How do you want the result? Printed lines on standard output? One for
each pair of connected nodes, as you have shown it below "result"? Or
collected in another fact?

[rules-users] Help write rule drools

[nill]

My structure is composed of 2 classes (Node, Link)
class Node {
List  out;
List  in;
}
class Link {
Source node;
Target node;
}

they are inserted as facts in working memory.

I have to write a rule that will unite for each node joins the links that
have the same destination, and if there is then the inverse must also join
the latter.

eg.
A - link1 -> B
A - link2 -> B
A - link3 -> C
C - link4 -> D
B - link5 -> A

result
A - link1 + link2 +link5 -> B
A - link3 -> C
C - link4 -> D

Can anyone help me?

Yes, I had imagined something like that was the case.

My original reasoning was the following; 

At the moment when the $e1 event arrives, time is Now and it is true that there 
is no second event. 
However, there is no way for the engine to know at Time=Now whether or not the 
second event is going to arrive within the required time period (this 
after[0,1m] $e1)
Surely, the engine needs to wait until (at least) Time=Now+1m before firing the 
rule, at least in the second case, because it is not possible to establish the 
truth or falsehood of the second criterion until 1m has past since the first 
event arrived because the second event might arrive, right?

Well, that's what I thought at least!

Yes, it is, and you are in good company. - A thorough study of the
temporal operators or reading Hawking's A Short History of Time helps,
either one ;-)

The word is "illuminative" rather than "interesting". Take this one:

$e1: Event($location: properties["location"] && ...)
not Event(, this after $e1)

The $e1 Event is here, Time is Now. It's most certainly true that
nothing is here after Now! - And the next one:

$e1: Event($location: properties["location"] && ...)
not Event(, this after[0, 1m] $e1)

Again, Event $e1 is here, Time is Now, and nothing is here after Now.
The operator does not instruct the Engine to wait!

Re: [rules-users] Help with event not found over window query

[daveor]

Thanks for your email below. I needed to refactor my code somewhat to get this 
technique to work but it solved the problem that I had. 

I was previously using fireAllRules() but I refactored the code to use 
fireUntilHalt() instead, which required some additional work to make a couple 
of other supporting features behave properly. I know you don't strictly need to 
do this, but it needed to be done anyway and it made sense to do it now.

I would have thought it was quite a common scenario where someone wanted to 
implement business logic such as:

- Something happens
- It is expected that something else will happen within a certain time period 
of the first thing happening
- If the second thing doesn't happen within the time period, generate an alert

I ran into trouble because my various rules (from my original email) wouldn't 
fire an alert as expected when I fed in simulated events. 

I'm curious as to why you think it's interesting that the four rules below fail 
to meet my expectation? I suppose it's the fact that I'm a drools newbie and 
the issue here is probably just my inexperience mapping business logic into 
drools rules.

Re: [rules-users] Help with event not found over window query

[Wolfgang Laun]

It would be interesting to discuss why each of these four rules fails to
meet you expectation. Mostly it's due to the engine not evaluating
exactly one minute after the "certain event" arrives.

The following rule fires 1 minute after the evaluation of the arrival
of an Event according to constraints and when no second Event
(according to constraints not shown) has arrived since then.

rule "Something Else" dialect "mvel"
timer ( int: 1m )
when
$e1: Event($location: properties["location"] && ...)
not Event(..., this after $e1)
then
   ...
end

[rules-users] Help with event not found over window query

[daveor]

Hi there, 

I'm a drools newbie and I wonder if someone could help me. I'm using drools
6.0.1 and I'm trying to write a rule that fires when:

1) a certain event is seen and 
2) a second event is not seen within a certain period of time (1 minute in
the examples below) after the first event is seen

I have tried the following LHS patterns:

rule "Something" dialect "mvel"
when
$e1: Event($location: properties["location"] && ...)
not Event(, this after $e1)
then
//do stuff
end

rule "Something" dialect "mvel"
when
$e1: Event($location: properties["location"] && ...)
not Event(, this after[0, 1m] $e1)
then
//do stuff
end

rule "Something" dialect "mvel"
when
$e1: Event($location: properties["location"] && ...)
List (size == 0) from collect (Event(..., this after $e1) over
window:time(1m))
then
//do stuff
end


rule "Something" dialect "mvel"
when
$e1: Event($location: properties["location"] && ...)
List (size == 0) from collect (Event(...) over window:time(1m))
then
//do stuff
end

The unwanted behaviours are as follows:

In the first case, the rule fires immediately after the first event is
inserted. 
In the second case, the rule fails to fire if the second event is seen (as
expected) but the rule does not fire if the second event is not seen within
1 minute.
In the third and fourth cases, the rule fires immediately after the first
event is inserted.

Event is a java class with a hash map of properties, defined with the
following metadata:

declare Event
@role(event)
end

I would really appreciate if someone could help me out here. 

Thanks and let me know if you need any more info.

Dave

[rules-users] help with drools 6

[dwipin]

Hi, 

I am trying to create a project using Drools 6 with Spring.

I have drools-spring-6.0.0.Beta2 as the dependency as
drools-spring-6.0.0.Final is not available.

I am unable to get the  tag to bind in the spring
application-context file. Can some one post a sample appCtx file with the
kmodule xsd schema location specified ?

Also, is there a working sample of using Spring with Drools 6 anywhere ?

Thanks, 
Dwipin Chandran.

there ist the "exists" CE,well documented in Expert's section 4.8.3.6.4.

But then you'll have trouble accessing the order id of this anonymous existence.

Again, I recommend using what I call an auxiliary "peephole fact" to
keep track of the latest pair of PriceChange and Signal, possibly with
a reference to the OrderCreated.

Also, the "magic"  if value 1234 doesn't look kosher to me, too.

Re: [rules-users] Help on writing a rule

[Demian Calcaprina]

Mauricio,

In fact, I used to have this and the price change without window:length..
but
when
t : PriceChange()
signal : Signal( id == "1234" )
not OrderCreated( id == "1234" ) over window:time (1m)

But this will cause more and more duplicates orders (and it have sense!). I
added the length window to 1, as I would only like to create an order if
there is some signal in the window, it can place an order..

Re: [rules-users] Help on writing a rule

[Demian Calcaprina]

Yes! I receive many price change events.. but, as I am using window length
= 1, I would expect to have the activation cancelled for the previous one?

I am not sure how to express this:
"when there is some price change, and some signal, and there has not been
any order over the last minute, then place an order"

The price change and signal are like "existence" facts.. "If there is some
price change change.." "if there is some signal ..."

Would this be another way to achieve what I am trying to do?

Thanks,

Demian

PS: This is a simple rule, but then, the idea is to have more complex
rules.. like, if there has been 10 signals in the last time, place an
order, etc.

Just curious here, why do you have this -> signal : Signal( id == "1234" )
over window:length(1)?

Re: [rules-users] Help on writing a rule

[Davide Sottara]

Am I wrong or do you have two PriceChange events - 392 and 394 ?
If so, you can expect two activations.. when you fire al rules, one of
the two
will insert the OrderCreated, which in turn will cancel the other

[rules-users] Help on writing a rule

[calcacuervo]

Hi Guys. I have one quesiton on how could I implement my rule.
I have this rule:
when
t : PriceChange() over window:length(1)
signal : Signal( id == "1234" ) over window:length(1)
not OrderCreated( id == "1234" ) over window:time (1m)
then
insert(new OrderCreated("1234));

Basically, when there is some signal and some price change, create a new
order if  there has no been any other order in the last minute.
But this sometimes is being fired twice:
12:31:01,121 INFO  [org.drools.audit.WorkingMemoryConsoleLogger] (Camel
(camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED
rule:ertetr activationId:ertetr [393, 392, 0] declarations: t=PriceChange
[](392); signal=Signal@1413ddef(393)
12:31:01,160 INFO  [org.drools.audit.WorkingMemoryConsoleLogger] (Camel
(camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED
rule:ertetr activationId:ertetr [393, 394, 0] declarations: t=PriceChange
[](394); signal=Signal@1413ddef(393)

I think that, when the 1m window have passed, it creates twice the
activations, as I have not called fire all rules yet. Does is make sense? Do
you have some idea on how could I implement this rule? "when there has been
some price change and some signal, and I did not create a new order in the
last minute, just create a new order".

Thanks in advance!

Demian

Re: [rules-users] help on drools guvnor

[Stephen Masters]

Have you tested that the rules fire when you load them as DRL?

It would probably be worth showing us what EmployeeMap looks like and the rule 
which you expect to fire if there is an EmployeeMap in working memory.

The Drools version would also be useful.

[rules-users] help on drools guvnor

[pritha.ghosh]

Hi,

I am not able to run rules from .pkg resources.

Knowledgesession is getting populated with package and rules inside the 
packages but when I am firing ksession.fireAllRules(); no rules are getting 
executed.

Below is my program

final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

// Use this line if calling rule defined using guvnor package
org.drools.io.impl.UrlResource urlResource;
try {
  urlResource = (org.drools.io.impl.UrlResource) 
org.drools.io.ResourceFactory
  .newUrlResource(new 
java.net.URL("http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/OBSPOC/OBSSNAP/OBSPOC_OBSSNAP.pkg";));


  urlResource.setBasicAuthentication("enabled");
  urlResource.setUsername("admin");
  urlResource.setPassword("admin");
  kbuilder.add(urlResource,ResourceType.PKG);
}
 catch (MalformedURLException e) {
System.out.println("malformed URL");
e.printStackTrace();
  }
catch (Exception e) {
  // TODO Auto-generated catch block
  e.printStackTrace();
}
// create the knowledge base
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();




// Check the builder for errors
if (kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors().toString() + 
"");
throw new RuntimeException("Unable to compile the rule 
file.");
   }else{
System.out.println(".Rule File is Read 
Successfully");
}

// get the compiled packages (which are serializable)
final Collection pkgs = kbuilder
.getKnowledgePackages();

// add the packages to a knowledgebase (deploy the knowledge packages).
  //  final KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
 kbase.addKnowledgePackages(pkgs);


final StatefulKnowledgeSession ksession = kbase
.newStatefulKnowledgeSession();

ksession.addEventListener(new DebugAgendaEventListener());
ksession.addEventListener(new DebugWorkingMemoryEventListener());

 EmployeeMap employeeMap = new EmployeeMap();
employeeMap.setEmployeeCountry("INDIA");
employeeMap.setEmployeeID(1);
employeeMap.setEmployeeName("USERP");

ksession.insert(employeeMap);
 ksession.fireAllRules();


ksession.dispose();


Thanks,

[rules-users] Help with DefaultAgenda.java

[Mallory]

Hello,

I have tried to change the source code of DefaultAgenda.Java by adding the
code below:

 //drools orginial sequential code
  /*
while ( continueFiring( fireLimit ) && fireNextItem( agendaFilter )
) {
fireCount++;
fireLimit = updateFireLimit( fireLimit );
this.workingMemory.executeQueuedActions();
}
*/


//code with concurrency

InternalAgendaGroup myGroup = (InternalAgendaGroup) getNextFocus();
fireCount = myGroup.size();

for(int i =0; i< fireCount; ++i)
{

new Thread(new Runnable(){
public void run()
{
fireNextItem( agendaFilter );

}
}).start();

}


I am getting an Errorjava.lang.NullPointerException because my code flow is
going to consequenceExceptionHandler ! = null exception.

else if ( this.consequenceExceptionHandler != null ) {

this.consequenceExceptionHandler.handleException(
activation, this.workingMemory.getKnowledgeRuntime(),

Could you kindly help me with this?

[rules-users] Help to implement my 1st planner

[André Rezende Fróes de Moraes]

Hello everyone, i'm trying to implement drools planner for my paper and it
is proving very hard taking in consideration that i never user it before.

I was able to reproduce the examples, even though i got very confused, but
i  undestood some things, but i'm really lost of how to implement my own
project/rule.


My paper is about service, I don't really know how to define it, but i'll
try to explain.

A given company receive several requests of maintence, repair, etc, all the
time, and it have a number of people to solve that, these technicians. It's
something like the nurse roaster but wy to simpler.

An issue can pop at any minute, it have a starting time and an estimated
time to be acomplished.

The technician have work for a fixed amount of time, but he have the start
time and the end time of work, that I want to use to assign the issue.

I've created the class Technician

Technician



import java.util.Date;

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("Technician")
public class Technician extends AbstractPersistable {

private int engId;
private int workTime;
private Date startWorkTime;
private Date endWorkTime;

private Technician technician;

public Technician(int engId, int workTime, Date startWorkTime,
Date endWorkTime) {
super();
this.engId = engId;
this.workTime = workTime;
this.startWorkTime = startWorkTime;
this.endWorkTime = endWorkTime;
}

public int getEngId() {
return engId;
}

public void setEngId(int engId) {
this.engId = engId;
}

public Date getStartWorkTime() {
return startWorkTime;
}

public int getWorkTime() {
return workTime;
}

public void setWorkTime(int workTime) {
this.workTime = workTime;
}

public void setStartWorkTime(Date startWorkTime) {
this.startWorkTime = startWorkTime;
}

public Date getEndWorkTime() {
return endWorkTime;
}

public void setEndWorkTime(Date endWorkTime) {
this.endWorkTime = endWorkTime;
}

public Technician getTechnician() {
return technician;
}

public void setTechnician(Technician technician) {
this.technician = technician;
}

}



Issue class



import java.util.Date;

import com.thoughtworks.xstream.annotations.XStreamAlias;

@XStreamAlias("CloudComputer")
public class Issue extends AbstractPersistable {

private Date startTime;
private Date estimatedTime;

public Issue(Date startTime, Date estimatedTime) {
super();
this.startTime = startTime;
this.estimatedTime = estimatedTime;
}

public Date getStartTime() {
return startTime;
}

public void setStartTime(Date startTime) {
this.startTime = startTime;
}

public Date getEstimatedTime() {
return estimatedTime;
}

public void setEstimatedTime(Date estimatedTime) {
this.estimatedTime = estimatedTime;
}

}



and here i got lost. I'm trying to schedule the technician to these issues
based on the estimated time and in the time left of technician.

I accept any kind of help or comment, I need it for next monday, i'll be
tunned everytime on this trying to make it happen.

Thanks for your time

[rules-users] help with designing / implementing a way for users to write their own rules

[kurrent93]

Dear drools experts

Can I get some ideas on how best to do the following. 

I would like users of my app to be able to write their own rule(s). For
example, if Joe User buys an item that is more that $200 then he uses XYZ
shipping. If he does not select shipping the he uses ABC shipping. 

More precisely, how can I offer the ability, using Guvnor, for the end user
to write a rule, that does not give him the ability to modify a rule
condition regaring user id. The example above, of coures, has a condition
that if user is 'Joe User'. 

There are very many places in the app where users should be able to write
rules, so it would be nice to use (embed) guvnor, rather than writing a
special UI for each situation.

Any suggestions welcome.

Br
Anton

Hi Toni,

It's very interesting to know it. It is possible that it is a bug. I did the
test several times but the results are the same.

Best regard

Must be a bug, perhaps verifier thinks these two rules are in different 
packages.

I can take a look at this next week.

[rules-users] Help please!!!

[paco]

I want to detect the conflict between the rules with Drools Verifier. For
example the first condition of the second rule is present in the first rule
and the actions to perform are the same in both rules as they demonstrate in
the following case. It works very well when these rules belong to the same
drl file.
- fichier  a.drl---
rule "a"
no-loop true
ruleflow-group "group1"
dialect "mvel"
when
A==0
then
Action1
end
rule "b"
no-loop true
ruleflow-group "group1"
dialect "mvel"
when
A==0 && B==1
then
Action1
end

The problem arises when I separated its rules and that I have to put each in
its own file
  a.drl
rule "a"
no-loop true
ruleflow-group "group1"
dialect "mvel"
when
A==0
then
Action1
end

--b.drl
rule "b"
no-loop true
ruleflow-group "group1"
dialect "mvel"
when
A==0 && B==1
then
Action1
end
I can no longer detect this problem with Drools Verifier.
Does anyone ever encountered this problem?
How can I do to write a small program to audit if this case?

My master thesis  is to develop a model interface that allows the
doctor to pose
the question for the patient. it consists of an interface and a database

 The purpose of the ontology is to implement the interface model that

and then clicking a button data are displayed which are imported for the
ontology weight the answer and then if the readings are not in good clicks
a button to display other data but not displayed the first time and if the
election is made on a data. By clicking a button to display the data that
are connected to select data and then validate the choice.

Please can you guide me to make this work?

can you give to me  a detailed description and the simplest methods to
follow and i inform you about all the information concerned my
environment to lead a good results because i'm a beginner in this domain ?

If there is any point on the ontology create or something missing you
can tell me because this is the first that I work with ontologies.

 so I just need to  realized this little application to validate the model
interface and the ontology and I like that you guide me.

Attached is the interface model and the ontology.
I await your advise and your help.

[rules-users] Help

[seagull]

Hi everyone,

I am new to drools.net and I am testing some basic commands but can't seem
to find help anywhere! I am trying to print the contents of a variable but
for some reason, the contents are not printed! The first line (i.e. hello)
on the other hand is being printed.. Is there a common mistake I may be
doing?

Thanks!

rule "testing"
when
p: Person (name == "john")
then
Console.WriteLine ("hello");
Console.WriteLine (p.name);
end

[rules-users] Help needed - Repository not getting initialised?

[Praveen]

Hi,

Repository is not getting initialised, throws NPE.
Please advise.
TIA.

public static Repository repository;

public static Session getSession() throws Exception {
return getSession(true);
}

public static synchronized Session getSession(boolean erase) {
try {
if (repository == null) {

if (erase) {
File repoDir = new File("repository");
System.out.println("DELETE test repo dir: "
+ repoDir.getAbsolutePath());
RepositorySessionUtil.deleteDir(repoDir);
System.out.println("TEST repo dir deleted.");
}

JCRRepositoryConfigurator config = new
JackrabbitRepositoryConfigurator();
String home = System
.getProperty("guvnor.repository.dir");
  
repository = config.getJCRRepository(home);

Session testSession = repository
.login(new SimpleCredentials("alan_parsons",
"password".toCharArray()));

RulesRepositoryAdministrator admin = new
RulesRepositoryAdministrator(
testSession);
if (erase && admin.isRepositoryInitialized()) {

admin.clearRulesRepository();
}
config.setupRulesRepository(testSession);
return testSession;
} else {
return repository.login(new SimpleCredentials(

}
} catch (RepositoryException e) {
throw new IllegalStateException(e);

They can recalculate just fine -- the underlying AccumulateData is just a

Re: [rules-users] Help with troubleshooting rules/Drools

[Robert Crawford]

I've rolled back to 5.2.0 and it seems to be doing better. Almost an hour of
uptime.

I already have a custom consequence exception handler -- I think it's
cribbed from that link, even. But this exception doesn't appear to happen
during the execution of a consequence -- I *think* it's during an event
expiration, but I can't swear to that.

The exception may happen during working memory operations (e.g., an insert),
so there isn't even a rule active.

Which version of Drools are you using? In my case, switching from Drools
5.2.0.Final to Drools 5.3.0.Final broke 47 of my unit tests (1 error and 46
failures). The one that now gives an error, shows this stacktrace (similar
to yours):

[rules-users] Help with troubleshooting rules/Drools

Any advice on how to troubleshoot problems? I have a fairly simple set of
rules (a couple dozen), but keep having problems with fatal exceptions. The

No mention of a rule name, so where do I begin?

My architecture is simple: one thread ran fireUntilHalt(), other (multiple)
threads inserting objects. Should I synchronize on the session so only one
thread is inserting at a time?

There's one rule that triggers a large number of inserts, and it used to
give me problems, but I've moved those inserts into Commands and those
problems seem to have gone away.

Any advice would be welcome, no matter how basic you think it is! Thanks!

Re: [rules-users] Help! Activations firing out of salience order

[darktyco]

I had to upgrade to 5.2 to get away from the same salience bug. So far 5.2
has been very good to us other than the outrageous amount of memory it takes
to load up a large rule base (which you can partially get around using the
latest mvel jar).

There used to be a subtle bug in the PriorityHeapQueue containing the 
activations.

See https://issues.jboss.org/browse/JBRULES-3044

-W
2011/10/18 Swindells, Thomas mailto:tswinde...@nds.com>>
In our project we have been experiencing a large number of intermittent unit 
test failures when we are testing our rules (on drools 5.1.1).
After a lot of debugging, examining our rules for logic errors, experimenting 
and generally scratching our head trying to work out what is wrong, we have 
noticed that sometimes (but very intermittently) activations are firing in the 
wrong order.

In our rulebase we have two rules, Rule A salience 80 and Rule B salience 70. 
Whilst debugging we made Rule A and B are identical other than rule B having 
some additional constraints on the end.
Dumping out the agenda events we have observed the following actions occurring:
BEFORE_FIRED rule X
CREATED_ACTIVATION Rule A
CREATED_ACTIVATION Rule B
AFTER_FIRED rule X

... (no references to either rule/activation)

BEFORE_FIRED Rule B
CANCELLED Rule A
AFTER_FIRED Rule B

How can Rule B be firing before Rule A when both activations exist?
Does anybody know of any bugs in 5.1.1 that may be causing this?
We have a branch of code on 5.3 and that also has had intermittent unit test 
failures, we've not had chance to examine whether this is the same pattern or 
just a different logic issue.

Please help,

Thomas

Re: [rules-users] Help! Activations firing out of salience order

[Swindells, Thomas]

Ouch looks like we and anybody on 5.1.1 needs to desperately update then.
Though I am rather concerned by this issue 
https://issues.jboss.org/browse/JBRULES-3211  "Rules fires on incorrect 
condition" - has this been looked at/is the issue correct as a rules engine 
which fires random rules when it shouldn't would be problematic!

2011/10/18 Swindells, Thomas mailto:tswinde...@nds.com>>
In our project we have been experiencing a large number of intermittent unit

After a lot of debugging, examining our rules for logic errors, experimenting

How can Rule B be firing before Rule A when both activations exist?

[rules-users] Help needed - how to get Number and intValue in Guvnor

[Praveen]

Hello,

I am new to Drools and trying to write rules using Guvnor GUI.
I have uploaded POJO's that are required for my rules.
I am facing issue trying to get Number()(the one in Bold-Italics) and
intValue in the Guvnor GUI.
Below is the rule for reference, its taken from one of the examples provided
in Drools Planner.


// Accumulate hard constraints
rule "hardConstraintsBroken"
salience -1 // Do the other rules first (optional, for performance)
when
$hardTotal : */Number(/)* from accumulate(
IntConstraintOccurrence(constraintType ==
ConstraintType.NEGATIVE_HARD, $weight : weight),
sum($weight) // Vote for
http://jira.jboss.com/jira/browse/JBRULES-1075
)
then
scoreCalculator.setHardConstraintsBroken($hardTotal.intValue());
end

Re: [rules-users] Help with URL resource caching

[benji2212]

Ah, I found my problem.  There was an issue with the builds, and my latest
changes weren't being applied to the environment I was testing in.  I've got
it working with the code I posted above.  Thanks.

[rules-users] Help with URL resource caching

[benji2212]

I'm using KnowledgeAgent to poll regularly for three DRL files hosted on a
web server.  If the web server goes down for any reason or one of the DRL
files becomes unavailable, the change scanner and knowledge agent
unsubscribe from the resource(s) that were unavailable.  

After reading some topics on the forum, I found that setting the
drools.resource.urlcache system property should correct this.  However, I've
been unable to get this to work properly.  The code I'm using is below.  Any
insight into what I'm doing wrong would be appreciated.  I'm using drools
5.1.1.

System.setProperty("drools.dateformat",
"MM/dd/");
System.setProperty("drools.resource.urlcache",
"C:\\Users\\000\\Documents\\rule-cache");

//start the scanner service and resource change 
notifier service
changeNotifier = 
ResourceFactory.getResourceChangeNotifierService();
changeScanner = 
ResourceFactory.getResourceChangeScannerService();
changeNotifier.start();
changeScanner.start();

kagent = KnowledgeAgentFactory.newKnowledgeAgent("My 
Knowledge Agent");
URL url = 
RulesRuntimeImpl.class.getResource(CHANGE_SET_PATH);
Resource drl = ResourceFactory.newUrlResource(url);
kagent.applyChangeSet(drl);


My change set file looks like this: 
http://drools.org/drools-5.0/change-set";
xmlns:xs="http://www.w3.org/2001/XMLSchema-instance";
xs:schemaLocation="http://drools.org/drools-5.0/change-set
drools-change-set-5.0.xsd" >

type="DRL" />
http://mysite.com/test/SecondDecisionTable.drl";
type="DRL" />
http://mysite.com/test/ThirdDecisionTable.drl";
type="DRL" />



and the output I get when a resource in the change set becomes unavailable:

Based on the stack trace I would guess that the file Sample.pkg contains a
serialized KnowledgeBase and not a serialized KnowledgePackage. Maybe you
could try to do your export like this:

KnowledgeBase kbase = ...;
KnowledgePackage kpackage = kbase.getKnowledgePackages().iterator().next();
FileOutputStream fos = new FileOutputStream(new File("c:/Sample.pkg"));
DroolsStreamUtils.streamOut(fos, kpackage);

Re: [rules-users] help! rule"rule_key" failed to predicate

[Wolfgang Laun]

The "package" declaration must be first.

You don't have to insert the "dialect" attribute into each rule.

Please consult the manual when programming.

Re: [rules-users] help! rule"rule_key" failed to predicate

[FrankVhh]

Hi,

I thnik you might need to reposition dialect = "mvel". The compiling error
will go away if you put it inside each of your rules. See example:

rule "system will execute 'tc' command"
   
 when
dialect "mvel"
eval(Server.Message>8388608)
 then 
 System.out.println("The network is so crowd that it needs repairing.");
Runtime.getRuntime().exec("tc");#give the authority and execute the "tc"
command
end
 
rule "caution"
dialect "mvel"
when 
eval(Server.Message==8388608)
then 
System.out.println("caution!The network maybe will get blocked very
soon.");
end 
 
rule "fluent network"
  dialect "mvel"
  when
  eval(Server.Message<8388608)#conditions
 then 
  System.out.println("the current network is very good");#actions
end

Also, mvel is needed to make the "eval" statement work. In your case, it
might not be needed to work with eval at all.

WHEN Server.message <  should work as well. Providing you have an
attribute message in Server with a getter defined.

Regards,
Frank

[rules-users] help! rule"rule_key" failed to predicate

[赵慧]

 hello,everyone! I wrote a rule with Drools, I compile the program and get the 
errors as follows: 

[3,0]: [ERR 103] Line 3:0 rule 'rule_key' failed predicate: 
{(validateIdentifierKey(DroolsSoftKeywords.RULE))}? in rule
[3,9]: [ERR 101] Line 3:9 no viable alternative at input 'com' in rule package
[7,0]: [ERR 101] Line 7:0 no viable alternative at input 'import' in rule 
package in rule sample  

I don't know how it happened, looking forward to your reply! thank you !!! 
 
PS: My rules are here:
 dialect "mvel"
package  com.sample
import com.sample.Server;

rule "system will execute 'tc' command"
   
 when
eval(Server.Message>8388608)
 then 
 System.out.println("The network is so crowd that it needs repairing.");
Runtime.getRuntime().exec("tc");#give the authority and execute the "tc" 
command
end
 
rule "caution"
when 
eval(Server.Message==8388608)
then 
System.out.println("caution!The network maybe will get blocked very 
soon.");
end 
 
rule "fluent network"

Re: [rules-users] help! rule"rule_key" failed to predicate

[Wolfgang Laun]

How can we help you if you don't show us the text of your .drl file?

All I can see is that the DRL parser could not find  "rule" (failing several
other alternatives) and then found the identifier "com" and didn't know what
to do with it.

This happens in line 4, position 0 (a misspelled "import"?) and 9 ("com").

Re: [rules-users] help! the field *** is not visible

[Wolfgang Laun]

Still, accessing the class field com.sample.Server.Message in eval() in this
way is almost certainly not a good approach.

But note that
   dialect "mvel"
may be written preceding all the rules it should apply to.

Re: [rules-users] help! the field *** is not visible

[John Peterson]

Try adding 'dialect "mvel"' (no single quotes) after the rule name to the top 
of each of the rules.  I have seen this error before and doing this resolved 
the issue.

Re: [rules-users] help! the field *** is not visible

[Michael Anstis]

A better approach would be to use:-

rule "system will execute 'tc' command"
 when
Server(message>8388608)
 then
 System.out.println("The network is so crowd that it needs repairing.");
  Runtime.getRuntime().exec("tc");#execute the "tc" command
end

This assumes you insert Server facts into working memory and they have a
"getMessage" property.

Normally you'd use eval when you are unable to leverage DRL. Their use is
normally discouraged. Also, your usage is incorrect; please read the
documentation.

With kind regards,

Mike

hello,everyone!I wrote a rule with Drools,but the error told me that the field 
Server.Message is not visible, I can't find how it happens. Please help me, I 
am almost exhausted with it. thank you.
the rules are as follows:
 
package com.sample
import com.sample.Server;
 
rule "system will execute 'tc' command"
 when
eval(Server.Message>8388608)
 then 
 System.out.println("The network is so crowd that it needs repairing.");
  Runtime.getRuntime().exec("tc");#execute the "tc" command
end
 
rule "caution"
when 
eval(Server.Message==8388608)
then 
System.out.println("caution!The network maybe will get blocked very 
soon.");
end 
 
rule "fluent network"
  when
  eval(Server.Message<8388608)#conditions
 then 
  System.out.println("the current network is very good");#actions

Re: [rules-users] Help with Accumulate function

[Dwipin C]

Thanks Wolfgang. 

The issue here is that the accumulation has to happen at a higher level in
the object hierarchy, "Position" in this case. However, this is no direct
link between Position and PostitionPnlAttributionAmount ( which is being
accumulated). How do I tackle such a scenario?

$attibAmtType will be just one for the condition given, but there could be 
multiple $posPnlAmt within a Position. 

Thanks,
Dwipin

Well, this explains it - you'll have to find the selecting combination
of $posPnlAmt and $attibAmtType in a unique way, assuming there is
just one such combination.

Re: [rules-users] Help with Accumulate function

[Wolfgang Laun]

One way to exclude siblings for a fact X is to use a constraint such
as "there is no other X with an identifying, comparable id < than the
only one I want".

  X( $id: id, $interesting: interesting )
  not X( id < $id )

Re: [rules-users] Help with Accumulate function

[dwipin]

The issue here is that the accumulation has to happen at a higher level in
the object hierarchy, "Position" in this case. However, this is no direct
link between Position and PostitionPnlAttributionAmount ( which is being
accumulated). How do I tackle such a scenario?

Thanks,
Dwipin.

Re: [rules-users] Help with Accumulate function

[Dwipin C]

Without the accumulate function, following is the fire occurrence- 

$position : Position() - 2
$posScn : PositionScenario(scenario == 'SCEN-EOD', position == $position ) 
- 2 ( with all above facts)
$posScnGrp : PositionScenarioCurrencyGroup(positionScenario == $posScn, 
currencyType == CurrencyTypes.TRANSACTIONAL) - 2 ( with all above facts)
$posPnlAmt : PositionPnlAmount(pnlAmountType == "DTD", 
positionScenarioCurrencyGroup == $posScnGrp) - 3 ( with all above facts)

$attibAmtType : AttributionAmountType(attributionAmountType == 
"UNEXPLAINED/RESIDUALPNL") - 2 (just this fact)

All of them together without the accumulate fires it 6 times.

Repeated firing may be due to there being more than one scope for 
accumulating
the sum, as selected by the patterns leading up to the accumulate.

If you take only the patterns preceding the accumulate - how often does 
this fire and for which elements? You need a single combination of 
$posPnlAm and $attibAmtType.

[rules-users] Help with Accumulate function

[dwipin]

Hi, 
  I am having trouble implementing this rule with the accumulate function.
My rule requirement is - 
Aggregate all PnlAttributionAmounts with a type of "UNEXPLAINED" for all
Positions for a given day. 

Below is the code I have for this - 

$position : Position(date == $currDate) 
$posScn : PositionScenario(scenario == 'SCEN-EOD', position == $position ) 
$posScnGrp : PositionScenarioCurrencyGroup(positionScenario == $posScn,
currencyType == CurrencyTypes.TRANSACTIONAL) 
$posPnlAmt : PositionPnlAmount(pnlAmountType == "DTD",
positionScenarioCurrencyGroup == $posScnGrp) 
$attibAmtType : AttributionAmountType(attributionAmountType ==
"UNEXPLAINED/RESIDUALPNL") 

$totalPnlAttibAmt : BigDecimal() 
from accumulate( 
PositionPnlAttributionAmount(positionPnlAmount ==
$posPnlAmt, attributionAmountType == $attibAmtType, $pnlAttibAmt :
financialValue) 
,sum($pnlAttibAmt) 
) 

eval ($totalPnlAttibAmt > 1000) 

When I do it this way, the rule gets executed 6 times, basically for every
fact that evaluated to true. How do I restrict this? The rule should be
executed only if the final eval results in true. 

Thanks for any help, 
Dwipin.

Re: [rules-users] HELP - Problem creating package -validateUniqueRuleNames(PackageBuilder.java:830)

[Saleem Lakhani]

All my rules worked fine with Drools 3. NowI am trying to upgrade to
Drools 5.

I am using the following jar files to create binary (jar) files for my
rules from command line:

antlr-runtime.jar, drools-api.jar, drools-compiler.jar, drools-core.jar,
drools-decisiontables.jar, drools-jsr94.jar, drools-templates.jar,
janino-2.5.15.jar, joda-time.jar, jsr94.jar, jxl.jar, mvel2.jar,
xpp3.jar, xpp3_min.jar, xstream.jar,
org.eclipse.jdt.core_3.6.1.v_A68_R36x.jar


This is my DSLR:

package cit.coverage;
expander Coverage.dsl

rule "rrr"
auto-focus true
when
He is nice
then
He is happy
end

This is my DSL Coverage.dsl:

[condition][]He is nice=eval(true)
[consequence][]He is happy=eval(System.out.println("HA HA"))


I am trying to create binary(jars) using the following code:

KnowledgeBuilderConfiguration kbc =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();
kbc.setProperty("drools.dialect.java.compiler", "JANINO");
KnowledgeBuilder builder = null;
builder = KnowledgeBuilderFactory.newKnowledgeBuilder(kbc);

Reader drlSource = new
InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDrlSourc
e()));  
//ruleset.getDrlSource() = com/cit/myDrl.dslr
Reader dslSource = new
InputStreamReader(RVEngine.class.getResourceAsStream(ruleset.getDslSourc
e()));

builder.add(ResourceFactory.newReaderResource(dslSource),
ResourceType.DSL);
builder.add(ResourceFactory.newReaderResource(drlSource),
ResourceType.DSLR); <-- problem
 
 KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
 kbase.addKnowledgePackages(builder.getKnowledgePackages());


no matter what I type in my dslr (drl) file I get the following
exception on the highlighted line; 
I have 1 rule or 0 rule it still throws the same exception. Does it have

ah, events werent being evicted because RHS was only evaluated during

i have altered my test code according to your suggestion, to look like this:

public void testLargeBatches() {
Node node1 = new Node("node 1");
node1.setId(1L);
s.insert(node1);

clock.advanceTime(1L, TimeUnit.DAYS);

int batchSize = 4;

nodeIds.add(1L);
DateTime engineTime;

Re: [rules-users] help with diagnosing CEP performance issue

[Wolfgang Laun]

You are inserting a day's worth of backup events at a time. In this loop the
engine is forced to evaluate both rules, for an ever-increasing number of
events. It's the second rule that requires a comparison between any two
backup events, and this causes a quadratic increment in processing time.

CEP is short for "continuous event processing", and that's what you should
let the engine do, i.e., not only evaluate the conditions but also the
execute the consequences. This is done by calling fireAllRules() after each
insertion. Alternatively, consider running fireUntilHalt() in once thread
and insert in another thread.

Ideally, the test should generate events ordered by time, and the
pseudo-clock might be advanced due to the time stamp in the generated
events. This would give you a very close approximation to a production run.

(OT: your nick "me" is confusing other gmail users. I see your mail as if I
had sent it to myself. I was almost binning it.)

The delay you see may depend on the way you run the test with 40K events.
Please describe the sequence of insertions and calls to fire...(), the

[rules-users] help with diagnosing CEP performance issue

[me]

Hi.

im trying to demo drools-fusion for a system that processes backup events.
i have the following 2 CEP rules:

rule "Backup Not Succeeded For At Least 3 Days"
@ruleId(1)
when
Node($id : id)
not ( Backup(clientId == $id, $state: state == BackupStateEnum.FINISHED)
over window:time( 3d ) from entry-point "Backup Stream" )
then
//nothing for now
end

rule "Prune Previous Successful Backups"
@ruleId(2)
when
$prevBackup  : Backup($id : clientId,  state ==
BackupStateEnum.FINISHED) from entry-point "Backup Stream"
$newerBackup : Backup(clientId == $id, state ==
BackupStateEnum.FINISHED, this after $prevBackup) from entry-point "Backup
Stream"
then
drools.retract($prevBackup);
end

rule #2 is my attempt to cut down on memory usage. the problem is that rule
#2 slows down the processing very very considerably (2 orders of magnitude
slower when simulating batches of 40K events/day).

what would be my next step in trying to find the reason for it? my intuition
tells me that with 2 events in the system at any given time instead of 120K
(single node, 40K events/day 3 day window) i should have seen either a
speedup or reduced memory consumption (if not both) and yet the results im
seeing are the exact opposite.
is there anything im missing ? i could try adding some sort of
LastSuccessfulBackup "marker" object into main memory and updating it using
events from the backup stream, but then how would i express rule #1 ?

any help/clues/suggestions would be greatly appreciated,

   radai.

Re: [rules-users] Help required for Rule Creation

[Wolfgang Laun]

Usually creation times are in seconds (starting at some Epoch) and therefore
all you have to do
is ascertain that two integers don't differ by more than 30:

$first: File( pathname matches ..., $ct: creationTime )
$later: File( creationTime < ($ct + 30) )

[rules-users] Help required for Rule Creation

[kiran.nair]

Hi,

I want to create a rule for the following scenario:

1. Event 1 : A file was created under the directory "/root/ " (Comment:
I have implemented this using 'matches' in the rule file)
2. Event 2: If File was created under "/root/" then get all the files
created within a 30 seconds of Event1. (Comment: Confused! Don't know
how to do this!)

The dataset I have is of all the files created on the system + time of
creation.

Thanks in advance!

Rgds,
Kiran

Re: [rules-users] Help me understand this drools exception

[murphy]

You should enable the option for dump creation with:
-Ddrools.dump.dir="yourDirectory"
so you can take a look at the generated code
(Process_com_test_sample_0.java) and maybe debug it.

Re: [rules-users] Help needed in activationCreated and activationCanceled event

[Michael Anstis]

Please don't email me direct. I won't reply in the future. All questions and
answers are of value to the community as a whole.

To quote what I replied to an almost identical request a couple of days ago
and posted to the drools-user mailing list.

"AFAIK, Activation Cancelled events would trigger in reaction to the
revocation of a logically inserted fact that caused an activation to trigger
in the first place. It would not help identifying which pattern in a rule
was not matched causing your rule not to activate".

Re: [rules-users] Help require for "web actor" related task

[Ashish.zokarkar]

Hello Guys,

I am able to treat "Human Task" as web actor. What I did is, I created a new
WorkItemHandler and when I submit the jsp, in jsp I wrote code to complete
the work item.

But conceptually still i have doubts:
1. I can able to register WorkItemHandler with name "Human task" which by
default take "WorkItemImpl" and "DefaultWorkitemmaneger" as workItem amd
manager respectively. I want to register my own Work Item. How can I
register it? 
Any code snippet will be really helpful.

Thank you very much in advance.

[rules-users] Help require for "web actor" related task

[Ashish.zokarkar]

Hello,
I am newbie for Drools flow. I am trying to build work flow in which
according to condition I have to ask either person properties or user
properties. 
I am trying to embed it in web project. So I created 3 jsps.
1. Ask information about User or Product.
2. According to selection shows different options.
3. Display all the properties.

What I am trying is, remove all the forwards from jsp and put them in
workflow so that its easily supportable for new object as well.

I think I should use "Human Task" where I am taking user input.

Now i have below questions:
1. I am trying to use "Human Task". But I can see it supports only Web
Service Human task. Is it true???
2. How can I use "Human Task" in this situation? In examples, I can see, I
require EntityManagerFactory, mina Task which should run on some port. Is
these steps really necessary???
3. I am trying really simple POC where I require kind of web actor which
should wait till user click on "Submit" button and then proceed to next
step. Is any similar kind of support Drools have?? If yes how can i use it??
Small code snippets or doc link will be very helpful...

Thank you very much in advance..

[rules-users] Help : How do I retrieve the repository or uuid of assets from java code?

[Han Ming Low]

Hi,

I'm trying to construct a url in the format
http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/Guvnor.html#asset=4dae7ddf-4d97-4e6b-ab07-b0f5e9d41d9c
by replacing the #asset=[uuid]

Thus, I would need to know the uuid of each asset in the repository.

I have tried to use the following code

Repository repository;
JCRRepositoryConfigurator configurator = new
JackrabbitRepositoryConfigurator();
repository = configurator.getJCRRepository(
"C:\\Programs\\Drools\\5.1\\jboss-4.2.3.GA\\repository\\" );
Session jcrsession = repository.login(new SimpleCredentials("admin",
"admin1".toCharArray()));
RulesRepository rrepository = new RulesRepository(jcrsession);
or

RulesRepository rrepository = RepositorySessionUtil.getRepository();

My drools persistence is set to MySQL.
So, RepositorySessionUtil.getRepository() kind of work but because it is
retrieving from a new repository, so it does not serve the purpose.

When I put the code above into a jsp in exploded drools-guvnor.war in jboss,
I have the following error.

org.drools.repository.RulesRepositoryException:
javax.jcr.RepositoryException: The repository home C:\Programs\Drools\5.1\
jboss-4.2.3.GA\bin\repository appears to be in use since the file named
.lock is already locked by the current process.

 org.jboss.seam.web.ContextFilter.doFilter(ContextFilter.java:37)
 
org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

But, I'm not even sure if what I'm trying to do is correct.
What I want to do is to be able to retrieve the uuid of the assets in
repository from a web application.
Can someone please help in providing a snippet of code or point me in some
direction on what should I retrieve in order to query the repository.

Thanks.

[rules-users] Help needed in Rule flow in Guvnor

[Vignesh]

Hi,

I am using Rule flow in Guvnor for setting some value out of the flow which
would be used for my further processing. Below is what I'm trying to
achieve,

I have two rule groups in the rule flow, out of which the first one would
set a  pair in a Map which is a field in one of the bean class
declared Global for the package when ever each rule is executed in the set
of rules in the group and the next rule group would be required to have a
set of rules that needs to be executed against this Map which was set in the
first rules group and send the final result as output out of the flow.

I have defined the rules in the first rule group and set the Map with
necessary keys and values, but I was not able to read the Map in this second
rule group. I had tried this second rule group as a custom java code in my
Java part after the rules execution from guvnor and able to read the map
that was set from the first rule group and able set the final decision.

I want to know whether reading the Map from the second rule group which was
set in the first rule group is possible or not. Or kindly let me know
whether I'm missing anything here and needed to add any other logic to
achieve the same.

Thanks,
Vignesh

[rules-users] Help regarding populating values from presentation layer into Fact Typpes in drools

[Swapnil Sawant]

Hi,

In drools, I have seen that following functionalities have been implemented :


-  Creating a fact type which can be used in a rule

-  Creating rule by declaring functions or by using DSL

-  Testing the rule using test scenario


Here, I had a question regarding decoupling of fact types between my 
application and drools.

I wanted to whether writing a java code for adding values from 
form/database(i.e. my application) into fact types of drools package which I 
have created is must or is there any automated way for doing this ?

For example,

If new rule gets added which will result in changing fact (either modify 
existing or add new fact).
In this case one has to  write a code for populating presentation layer values 
into this newly modified/created fact type. Can this be automated..?

>From client support perspective -How to manage addition of New Rule to 
>existing Rule base..?

Re: [rules-users] Help : Enabling Role Base Authorization in Guvnor

[Jervis Liu]

Hi, the rolesProperties file (eg,  guvnor-roles.properties) configured 
in JBoss AS is not used by Guvnor authorization. Before you enable 
enable-role-based-authorization, you need to login and configure user 
permissions in Guvnor "Administration". For example, you need to give 
your "admin" user a full admin permission.

Hope this helps,
Jervis
