[rules-users] gwt-console

[Shanika Wijerathna]

Hi
Im new to drools. Im trying to get gwt-console work with jboss server. So I
downloaded the gwt-console code from svn (
http://anonsvn.jboss.org/repos/soag/bpm-console/trunk) and when I try
excecute mvn install command from trunk it gives me following error. I tried
googling but I couldn't find a way to get rid of this error. And also in
forums they say that we need to change pom.xml to use drools as defult
profile. Where I can change it? Thanks alot if some one can help me. Im
trying to start learning jboss drools and i have already installed jboss and
Guvnor.

What version of Guvnor are you using? When you said M1, did you mean the

Re: [rules-users] NullPointerException @ modify()

[H.C.]

I resorted to rolling back our Drools version to 5.0.1 and the code works
without changes. So...guess this must be a bug with 5.1.0-M1.

Re: [rules-users] removeKnowledgePackage Call Hangs!!

[malkhafaji]

Any help is appreciated. I am stuck on this. I stripped everything down to
two simple drls, and one of them loads the other as a new KP, and then tries
to unload it.

Any ideas why the removeKnowledgePackage could possibly throw a
NullPointerException in M1?? This is really hurting us as we are going live
with this in a couple of weeks or so.

Any help would be greatly appreciated!

[rules-users] get image of flow from xml

[Daniel Gimenes]

I'm trying to show an image of a workflow on a web page, based on it's xml.

I've first tried to do this by using drools-eclipse project functionality of
export workflows as images, but gave up because the project has many
dependencies.

Then I tried the drools-guvnor, which do exactly what I want, but it's
developed using GWT. My problem i'm having now is with using drools-guvnor
jar in my GWT project, and then i'll still have to integrate it with SEAM. I


want to know if this can be done. Have someone already done this before? Is
there a better way?

Re: [rules-users] Drools5 in tomcat 5

[Rubén Marrero]

thanks a lot! 


I'm trying to setup a decision service, _without_ having to code in java. 


I'm kind of swamped at the moment in other stuff but will get back to this ASAP 
and report back. 


Thanks again,

Asunto: Re: [rules-users] Drools5 in tomcat 5 

Examples below shows how to use drools Camel integration. With Camel 
integration, you can host drools rule engine as a Camel service. The 
service can be based on Web services, REST, JMS or whatever capabilities 
Camel offers. 
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-pipeline/drools-camel/src/test/java/org/drools/camel/component
 

You can also use Drools pipeline to expose a drools rule engine as 
service. For example, example below is exposing Drools through JMS: 
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-pipeline/drools-messenger-jms/src/test/java/org/drools/runtime/pipeline/impl/SimpleJmsMessengerTest.java
 

If you do a google search, you can also find some nice docs on how to 
use drools-pipeline to expose drools engine as web services etc. 

Hope this helps, 
Jervis

Re: [rules-users] error while executing business rules

[Esteban Aliverti]

Any reason why you are using Drools 4?
Try to figure out which rule is failing and post it here.
I have never used Drools 4. I started from V5.

Try to be a little more specific. Which version of drools are you using? How
your rule looks like? What are you trying to do?

Best,

[rules-users] error while executing business rules

hi friends ,

I am getting the error while executing the business rule



[2010-05-17 09:37:22,419] [FATAL] Error occured while creating rules package
for parameter : 568 (BusinessRuleServiceImpl.java:2285)

Re: [rules-users] Time Taken To Load Rule Resource

[Esteban Aliverti]

Yes, you can compile your rules once and save them as binary files. Here is
a code snippet to do that:

   * KnowledgePackage pkg = (KnowledgePackage) kbuilder** **
.getKnowledgePackages().iterator().next();*
*FileOutputStream out = new
FileOutputStream("/some/file.pkg");*
* **try {*
* **DroolsStreamUtils.streamOut(out, pkg);*
* **} finally {*
* **out.close();*
* **}*

The code above only uses kbuilder's first package.
The way you load a binary package is the same as you do for DRL files:

*
kbuilder.add(ResourceFactory.newFileResource("/some/file.pkg",
ResourceType.PKG);
*

Hope you find this useful!

Best,

Re: [rules-users] Time Taken To Load Rule Resource

[Adeyinka Timi]

Thanks for your reply!

No particular reason. Is there a better of going about this - avoid
compilation of rules everytime?

Is there any reason why you need to compile the rules every time your app

Hi guys,

 

I have a drools application running that takes about 7 seconds to run. 5
seconds of this time is used in parsing 2 DRL files that 200kb (6200 lines
of code) and 34kb (1400 lines of code). Do you guys have any tips or any

These files were removed recently from repository. You need to execute *mvn

Re: [rules-users] Jbilling Drools performance

[Antonio Anderson Souza]

Dear Thomas,

My first try was to use the matches and the performance was slower about 3
minutes to process only one CDR, after this benchmark and some research I've
tried to use the per digit comparison.

The order of this table that I sent is inverted, the most general entries
must be analyzed first.

I'm still analyzing how to change JBilling to use per digit comparison to
benchmark the performance of this solution.

Thank you very much for your tips.

Re: [rules-users] [Drools Fusion] Can't detect 2 occurrences with sliding window

[Xavier Coulon]

Hello Wolfgang,

Thanks for you answer. I changed my JUnit test method to the following :

@Test
public void testActivity() throws IOException, ParseException,
InterruptedException {
// parse the log file
Resource logFile = new ClassPathResource(
"activity/activite18h20-18h30-tpcnop01s-extract.log");
// converter and inject tracks in the session,
List logLines = FileUtils.readLines(logFile.getFile(),
"UTF-8");

// fire all rules
session.fireAllRules();
LOGGER.info("loading events");
// load events from stream
for (String logLine : logLines) {
Operation operation = LineConverterUtil.getOperation(logLine);
LOGGER.debug("Moving clock from "
+ (new Date(clock.getCurrentTime())).toString() + " to "
+ operation.getDate());
*clock.advanceTime(operation.getDate().getTime()**
- clock.getCurrentTime(), TimeUnit.MILLISECONDS);
session.fireAllRules();
***// clock.advanceTime(10, TimeUnit.SECONDS);
LOGGER.debug("Inserting " + operation);
FactHandle operationHandle = entryPoint.insert(operation);
LOGGER.debug("Insertion done: " +
operationHandle.toExternalForm());

}
LOGGER.info("done with events");
// check...
Assert.assertTrue("Rule not fired...", listener
.isRuleFired("overActivity"));
}

But it still does not work : the first "operation" is retracted from the
session when the clock is moved (see my logs below), yet the window of 60s
is not expired (18:26:47 to 18:27:11)

Any idea ?

Re: [rules-users] Is it possible to access created Object inside RHS???

[Swindells, Thomas]

Yes,

How you do it depends on what you are wanting to do.
If you just want to use the newly created object from other rules then you 
should insert it into the knowledge base.
If you just want to pass back your newly created object into your application 
then the easiest way is to insert a global object into the knowledge base, you 
can then call methods on this object to communicate from the rules into your 
application.

If you want to do both then the best way is to insert it into the knowledge 
base and then use queries from your application to extract the facts you are 
interested in.

Reading 
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/html_single/index.html
 and looking at the samples and test cases in the drools codebase should help 
you get further.

[rules-users] Is it possible to access created Object inside RHS???

[Kuttiraja]

Hi,

I have some application using Drools.
Sample rule

rule "rule 1"
when
//some condition
then
Object a = new Object()
//Do Something with Object
end

is it possible to use this newly created object from the Application?

Thanks in advance

[rules-users] CHR 2010: Call for Participation

[Peter Van Weert]

 CALL FOR PARTICIPATION
CHR 2010


 7th International Workshop on Constraint Handling Rules
  associated with ICLP 2010 (part of FLoC 2010)
Edinburgh, Scotland, 20 July 2010
 http://dtai.cs.kuleuven.be/CHR/CHR2010/

   HIGHLIGHTS

* newcomers' welcome to CHR tutorial by Thom Frühwirth
* invited talk on the JBoss Drools business rules platform by Mark Proctor
* invited talk by Matt Lilley of SecuritEase, a leading stock broking system
* introduction to CHRiSM, a CHR-based probabilistic formalism, by Jon Sneyers
* presentation of the six accepted papers + two demos

  INTRODUCTION

The  Constraint Handling Rules  (CHR) language has  become a major  declarative
specification formalism  and implementation  language for  constraint reasoning
algorithms and  applications. Algorithms  are often  specified using  inference
rules, rewrite  rules, sequents,  proof rules,  or logical axioms  that can  be
directly  written  in CHR.  Its  clean semantics  facilitates  program  design,
analysis, and transformation. See the CHR website for more information:

   http://dtai.cs.kuleuven.be/CHR/

PROGRAM

The CHR 2010 workshop offers a very attractive and varied program.  Next to our
accepted technical papers, we have two invited speakers:  Mark Proctor from the
JBoss Drools  project, a  major open-source  business rule  platform, and  Matt
Lilley from SecuritEase, a leading stock broking dealing and settlement system,
and one of the most prominent industry users of Prolog and CHR.

Other  highlights  are the  first  practical confluence  checker  for CHR,  and
several  application-oriented  presentations, including  two demos  by students
from the  University of Ulm on using CHR with a  multi-touch interface: one for
automated music generation,  and one aimed at  providing long-term routing  for
fully autonomous sailing boats (in cooperation with the Roboat  project).

Because  many FLoC attendants  will be new to CHR,  we included  two additional
introductionary presentations: Thom Frühwirth will give a broad tutorial on CHR
in general, and  Jon Sneyers will introduce the  recent CHR-based probabilistic
formalism CHRiSM (also presented at the main ICLP conference).

The full workshop's program is available at:

   http://dtai.cs.kuleuven.be/CHR/CHR2010/programme.shtml

  REGISTRATION

Registration for the workshop can be done online at:

[rules-users] issue with drools-container and related (in it's classpath) projects

[kicho]

Hi all!

I have a question regardless drools-container eclipse projects from svn
trunk (drools-spring project to be precise). I've noticed that that
particular project is now missing .classpath and .project files. 

I have been reading posts about drools and spring integration and found them
interesting, but now i don't know what projects from the svn i need to
checkout, since the mentioned files are missing. 

Is there any particular reason for that?

Thanks in advance,
kicho

Re: [rules-users] [Drools Fusion] Can't detect 2 occurrences with sliding window

[Wolfgang Laun]

You are inserting Operation facts, interleaved with advancing the clock,
both of which correctly updates the agenda and eliminates the facts that
are pseudo-too-old to matter.

But you are never goiving the Engine a chance to fire - until it is
pseudo-too-late.

Either you call session.fireUntilHalt() in a separate thread or, for unit
test, call
fireAllRules() after each clock manipulation.

[rules-users] [Drools Fusion] Can't detect 2 occurrences with sliding window

[Xavier Coulon]

Hello,

I'm new to Drools (5.0.1) and i've tryied the following (basic) fusion rule
for a few days now without success.
The rule is to determine if a user performs 2 operations in the sliding
window of 60s. In such a condition, a log message should be triggered.

Here is my DRL code : 

# declare events
declare Operation
@role(event)
@timestamp(date)
end

rule "overActivity"
dialect "mvel"  
when
#condition : 2 operation in less than 1 minute
$operation1 : Operation() 
over window:time(60s) from entry-point "OperationStream"
$operation2 : Operation(this != $operation1, ipAddress ==
$operation1.ipAddress)  
over window:time(60s) from entry-point "OperationStream"
then 
#actions
System.out.println("over-active user " + $operation1.ipAddress 
);
end


And my JUnit test, using a PSEUDO Clock :

public class DroolsRulesTestCase {

static KnowledgeBase knowledgeBase;
StatefulKnowledgeSession session;
// FactHandle handle;
SessionPseudoClock clock;
WorkingMemoryEntryPoint entryPoint;
private TrackingAgendaEventListener listener;

private static final Logger LOGGER = Logger
.getLogger(DroolsRulesTestCase.class);

@BeforeClass
public static void globalSetup() throws IOException {
KnowledgeBuilder builder = KnowledgeBuilderFactory
.newKnowledgeBuilder();
ClassPathResource classPathResource = new ClassPathResource(
"rules/activity-fusion.drl");
Assert.assertTrue("Rules resource not found", classPathResource
.exists());

builder.add(ResourceFactory.newInputStreamResource(classPathResource
.getInputStream()), ResourceType.DRL);
Assert.assertFalse("Errors in builder:"
+ builder.getErrors().toString(), 
builder.hasErrors());
KnowledgeBaseConfiguration configuration = KnowledgeBaseFactory
.newKnowledgeBaseConfiguration();
configuration.setOption(EventProcessingOption.STREAM);
knowledgeBase = 
KnowledgeBaseFactory.newKnowledgeBase(configuration);

knowledgeBase.addKnowledgePackages(builder.getKnowledgePackages());
}

@Before
public void setup() {
KnowledgeSessionConfiguration configuration = 
KnowledgeBaseFactory
.newKnowledgeSessionConfiguration();
configuration.setOption(ClockTypeOption.get("pseudo"));

session = knowledgeBase
.newStatefulKnowledgeSession(configuration, 
null);
clock = (SessionPseudoClock) session.getSessionClock();
listener = new TrackingAgendaEventListener();
session.addEventListener(listener);
session.addEventListener(new 
TrackingWorkingMemoryEventListener());
entryPoint = 
session.getWorkingMemoryEntryPoint("OperationStream");
}

@SuppressWarnings("unchecked")
@Test
public void testActivity() throws IOException, ParseException,
InterruptedException {
// parse the log file
Resource logFile = new ClassPathResource(
"activity/extract.log");
// converter and inject tracks in the session,
List logLines = FileUtils.readLines(logFile.getFile(), 
"UTF-8");

// fire all rules
session.fireAllRules();
LOGGER.info("loading events");
// load events from stream
for (String logLine : logLines) {
Operation operation = 
LineConverterUtil.getOperation(logLine);
LOGGER.debug("Inserting " + operation);
LOGGER.debug("Moving clock from "
+ (new 
Date(clock.getCurrentTime())).toString() + " to "
+ operation.getDate());
clock.advanceTime(operation.getDate().getTime()
- clock.getCurrentTime(), 
TimeUnit.MILLISECONDS);
// clock.advanceTime(10, TimeUnit.SECONDS);
FactHandle operationHandle = 
entryPoint.insert(operation);

LOGGER.debug("Insertion done: " + 
operationHandle.toExternalForm());

}
LOGGER.info("done with events");
// check...
Assert.assertTrue("Rule not fired...", listener
.isRuleFired("overActivity"));
}
}

Re: [rules-users] Access to variables form sub-flows

[pvm]

Hi there,
Many thanks for your reply. i've done as you suggest, but the problem i have is 
perhaps a simpler one... i don't know how to access the variable in the rules 
in my sub-flow. My variable is called "isManager" and i can now pass it in ok, 
but not use it. E.g. if i write a rule as follows:

if

Agent() // there are plenty of these objects in my knowledge 
base...

then

system.out.println("found an agent, and the local variable is " +
 isManager);


i get an error "isManager cannot be resolved"


? How am i supposed to access a variable in the sub flow? (this is probably a 
dumb quesitons, but i just cant find out how to do it!).

Thanks,
Paul.

Hi PVM,


You have to declare the variable in both flows, the parent flow as well as the 
sub flow. Then you also have to map it to the sub flow node. To do that, in the 
parent flow click the sub flow node and in the properties map the variable in 
"Parameter In Mapping".


I hope it helps :)

Re: [rules-users] Jbilling Drools performance

[Swindells, Thomas]

My advice is to try just having a single column:
strValue matches "$param.*"
you could also compare the performance of that to
eval(strValue.startsWith("$param"))

Also presumably you are only wanting the first matching rule in your table to 
fire, looking at the table below drools will fire all of the matching rules, 
this will mean than any phone number with prefix 5511 will be charged at 0.4 as 
that will be the last rule to fire.

No problem.  I'm not sure how you'd do this in a decision table (it's probably 
pretty trivial) but in DRL you'd do:

rule "makePhoneNumber"
when
  s: String()
then
  insert(new PhoneNumber(s));
  retract(s);
end

With two caveats:

1) you need some conditions on the String matched if there are other Strings 
that don't make PhoneNumbers.
2) The rule could use a salience value higher than the pricing rules, but that 
isn't necessary.

Actually, there's a third caveat, and it's a big one: this won't work with 
sequential mode. This is because the rule above would alter working memory with 
the expectation that the pricing rules would react to the change.  If you want 
to use sequential mode you'll have to convert to PhoneNumber objects before 
hand.  I understand that you're using this Jbilling package, but is there no 
way you can put an intermediate adapter between the two?  It'd be as simple as 
inserting "new PhoneNumber(someString)" instead of "someString".

Dear Greg,

Thanks very much for your reply.

I'm using sequential mode = true

Is there a way to create this PhoneNumber class, and convert the String to the 
PhoneNumber object inside the Drools? Because I'm using a system called 
JBilling and it send the phoneNumber as a String.

Sorry if those are basic questions, but I'm a newbie in Drools...

Thank you very much,

Right off the bat I'd say try to get rid of the eval usage.  Can you put the 
phone number into an object like this:

class PhoneNumber {
  private char digit0;
  private char digit1;
  ///...same for the rest of the digits

  public char getDigit0() { return digit0; }
  public char getDigit1() { return digit1; }
}

Then the conditions would look like this:

digit0 == '$param'

Behind the scenes hopefully this will optimize better.  The use of eval won't 
optimize well.

Are you using sequential mode?  This might be a good candidate for that if 
setting the price does not trigger any other rules to fire.

Dear All,
I'm deploying  a JBilling using Drools in a Telecom Carrier in Brazil, and I'm 
using Decision tables in xls files to execute the pricing, my pricing table has 
about 40.000 rules, and I'm getting a terrible performance about 1.5 minute to 
execute the price of each CDR (Call Detail Record) mediated.

Follow bellow a small piece of my decision table:

Hi Ram, what problems did you see on JBOSS AS 6.0? I tried JBOSS AS 6.0 
recently with Guvnor 5.1, looks like this is a SEAM problem. Seam 2.1 
may not work with JBOSS AS 6. I need a further look into this.

Exception received:

At the same time, you can try JBOASS AS 5.0. Here is the instruction on 
how to deploy Guvnor in JBOSS 5.0:
