[rules-users] Non Spatial Map Reduce
I was reading the blog http://www.optaplanner.org/blog/2014/03/03/CanMapReduceSolvePlanningProblems.html and although the unsuitability of the spatial division of the problem makes sense, I'd like to understand why the problem can't be broken up differently. i.e. why can't any solution be loaded into n separate solvers with 1/nth of the moves, and then send the best solution to all the solvers, and repeat? -- View this message in context: http://drools.46999.n3.nabble.com/Non-Spatial-Map-Reduce-tp4028652.html Sent from the Drools: User forum mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Long pattern for Nurse Rostering
That does make sense. It sounds like I should be adding the facts as domain objects where the index is available instead of generating them during the solution. I was trying to reuse the existing ShiftType3DaysPattern class from the nursing example, but used more than I should have. The code I have is almost working, but it seems to create plateaus. I can give it a push by stopping the GUI, making some changes, and then restarting. So I'll add another rule to do that on it's own.

I'm trying to create a rule for a 15 day pattern.

Number[] numbers = new Number[] { wrap(5), wrap(6), wrap(4),
wrap(1), wrap(2) };
new RuleRunner().runRules(new String[] { Example3.drl }, numbers);
}
private static Integer wrap(int i) {
return new Integer(i);
}
}
The RuleRunner class is the same as given in the example and I do not think
I should give that here, since it will clutter the question. It simply
creates the KnowledgeBase, stateful session, inserts the facts as given in
the 'numbers' array above and then calls fireAllRules method on the session.
The rule file (Example3.drl) is:
rule Rule 04
dialect mvel
when
$number : Number()
not Number(intValue $number.intValue)
then
System.out.println(Number found with value: + $number.intValue());
retract($number);
end
The output I get is as follows:
Loading file: Example3.drl
Inserting fact: 5
Inserting fact: 6
Inserting fact: 4
Inserting fact: 1
Inserting fact: 2
Number found with value: 1
Number found with value: 4
Number found with value: 2
Number found with value: 5
Number found with value: 6
Not the correct expected ascending sorted order.
What might I be doing wrong? I cannot imagine that the drools rule engine
would be broken at this basic level.

[rules-users] DSL Build Problem
I'm looking for a little help on a problem we can't figure out with some DSL
errors during a build. We're working with version 5.3.0.Final on RSA 7.5.5.
The offending line of DSL is on the rule is:
Write qualifyingPoints on Result as $var01 * $var02
$var01 and $var02 are variables set in the WHEN part of this rule.
The offending line of code is translating to:
modify (Result){qualifyingPoints = $var01 * $var02};
When I execute the program that calls this rule, if fails during the build
process with the following:
Unable to Analyse Expression @Modify with (Result){qualifyingPoints = $var01 *
$var02 };
[Error: java/lang/String.isEmpty()Z]
[Near : {... @Modify with (Result){qualifyingPt }]
^
[Line: 1, Column: 9] : [Rule name=Qualifying Points rule 1']
If I modify the code to use an assignment and update instead of modify, it will
build without an error:
Result.setQualifyingPoints( $var01 * $var02 );update (Result);
Note that we only see this behavior on RSA. We do not see it on Eclipse (but
we need to use RSA).
I didn't find anything online so I thought I'd check to see if this is
something someone has seen before.
Thanks!

Re: [rules-users] 5.3.0.Final throws RuntimeDroolsException: Unable to merge resource attribute for type declaration
Edson,
Thanks for your feedback. I've have created an eclipse/maven project to
duplicate this problem but I couldn't figure out how to open an issue in Jira
(perhaps I don't have permission).
If I include all the dependent libraries in a zip file (for convenience) the
zip will be 7MB (which might not be so convenient after all).
Please let me know how I can open a new issue in Jira and/or how best to
deliver this project to you.

Hi, I'm using drolls 5.3 server with one rule in a _stateless_ session. I am sending a POJO to the server, having it check a few attributes, modify the attributes of the bean as needed then return the result.

I have three .drl files. The first is globals.drl that simply imports and
defines some global variables (e.g, a org.slf4j.Logger, etc.). This
globals.drl file also defines NormalizedEvent as follows:
declare NormalizedEvent
@role( event )
end
The second rules file (defaultRules.drl) contains default rules for aging out
old / stale events.
The third rules file has rules additional rules that are specific to a policy
being dynamically deployed to our application.
The compilation and loading process treats globals.drl as common header
file. That is, rules files are pre-pended with globals.drl before they are
compiled. For example:
String globals = readDrlfile(globals.drl);
String newRules = readDrlfile(rulesToAdd.drl);
knowledgeBuilder.add(ResourceFactory.newReaderResource(new
StringReader(globals + newRules)));
if (knowledgeBuilder.hasErrors()) {
throw exception ...
}
// No exception so compile succeeded --- BTW, it's using JANINO
knowledgeBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());
// ERROR
The first compile and load (globals.drl + defaultRules.drl) succeeds but I get
this exception when I try to compile and load an additional file (globals.drl +
additionalRules.drl).
This code was also written by someone not very familar with Drools but it was
working in 5.2 and now I need to get it working with 5.3Looks like there
were some significant code changes to AbstractRuleBase between these two
releases.
Any thoughts or suggestion here would be greatly appreciated.

Hi,
You can create two types of Model I'm Guvnor: 1) a declarative model, in which
case you can open the model and see the facts and fields; 2) upload a POJO
model, in which case the model screen only allows you to download the current
version.
When authoring rules in Guvnor you select a Fact (class) first and then click
on this to select fields.
By what you describe I get the feeling you may not have read Guvnor's
user-guide. Please do have a look.
With kind regards,

[rules-users] Are retracted events garbage collected in stateful session?
I am inserting a high volume of relatively large objects into a long-running StatefulKnowledgeSession in Stream mode. I use a rule to start a jbpm process when each event is received, and the last step retracts the event. I assumed these were all being garbage collected until my app server started running out of memory. I ran a profiler and saw that none of my event objects were ever collected. Is there any way of freeing references without disposing the working memory? This is not a good option for our app. I have read this post http://drools.46999.n3.nabble.com/Removing-facts-from-statefulknowledgeSession-s-memory-td1875795.html#a1881799 Removing-facts-from-statefulknowledgeSession-s-memory and several others, but my objects are all manually retracted. I just need to make them available for garbage collection.

[rules-users] Guvnor does not like my rule?
Noob alert, first post.
I have a rule that works fine when I run it in a JUnit test. I've imported it
into Guvnor (along with all my referenced pojos and functions) and it will not
build there. Here is the error:
Unable to Analyse Expression for (String curr : (ListString) $validList) {
ValidValue aValidVal = new ValidValue(curr); drools.insert(aValidVal); }; for
(int i=0; i$validList.size(); i++) { String curr = (String)$validList.get(i);
ValidValue aValidVal = new ValidValue(curr); drools.insert(aValidVal); };:
[Error: unexpected token: $validList] [Near : {... rr : (ListString)
$validList) { }] ^ [Line: 1, Column: 35]
What the rules is trying to do is run values from a set of records through a
validation function and then add each of the valid values as individual facts.
Guvnor apparently doesn't like the way the iteration of the list is being done.
I've tried a few different ways of iteration. Thanks in advance for any
advice.
Here is the rule:
when
$validList : List()
from accumulate(
InRecord($value :
value != ),
ListValid($value))
then
for (String curr : (ListString) $validList) {
ValidValue aValidVal = new
ValidValue(curr);
insert(aValidVal);
}
for (int i=0; i$validList.size(); i++) {
String curr =
(String)$validList.get(i);
ValidValue aValidVal = new
ValidValue(curr);
insert(aValidVal);
}

[rules-users] Error in Guvnor with Enumerations (5.1.1)
Reposting since I didn't get any takers. I'm hoping it might have been because
I sent it to the list on a Friday afternoon (2 weeks ago).
Hey,
I'm trying to utilize a load method for Guvnor, but I can't seem to get it
working. His is my DataHelper class (modeling it off the documentation):
package com.enumerations;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
public class DataHelper {
public ListString getQuestionNumberList(){
ArrayList returnList = new ArrayList();
Iterator it =
com.enumerations.DroolsTest.questionList.iterator();
while (it.hasNext()){
QuestionAndAnswer qAndA = (QuestionAndAnswer)it.next();
if (!returnList.contains(qAndA.getQuestionNumber())){
returnList.add((String)qAndA.getQuestionNumber());
}
}
return (ListString)returnList;
}
}
I've placed this (both as a .jar and .class file) in my JBoss installation
under
\jboss-4.2.3.GA\server\default\deploy\drools-guvnor.war\WEB-INF\classes\com\enumerations.
Using this syntax as an enumeration in Guvnor:
'QuestionAndAnswer.questionNumber' : (new
com.enumerations.DataHelper()).getQuestionNumberList()
I get the following errors:
[Enumerations] Unable to load enumeration data.
[Enumerations] [Error: failed to access property: getQuestionNumberList():

I am using Drools 5.1.1. Does anyone have any suggestions on what to do to
correct this error?

[rules-users] Rule Flow and Stateless Session
I'm having some difficulty getting a rule flow with a stateless session to work. Essentially, it is just executing the first task and then stops. I'm using Drools 5.1.1 and I just built the sample Drools by creating a new Drools Project. My rule flow is simple: Start-RuleGroup1-RuleGroup2-End I use the 2 rules from example, putting the Hello World in RuleGroup1 and Goodbye in RuleGroup2. Here's my code to run it: // load up the knowledge base KnowledgeBase kbase = readKnowledgeBase(); StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession(); KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newFileLogger(ksession, test); // start a new process instance Message message = new Message(); message.setMessage(Hello World); message.setStatus(Message.HELLO); ArrayList cmds = new ArrayList(); ArrayList dataList = new ArrayList(); dataList.add(message); cmds.add(CommandFactory.newInsertElements(dataList)); cmds.add(CommandFactory.newStartProcess(com.sample.ruleflow)); ksession.execute(CommandFactory.newBatchExecution(cmds)); logger.close(); When I run the rules, all I get is Hello World (no Goodbye cruel world). It does work with a Stateful Session using insert, startProcess, and fireAllRules, but this is a test using the rule flows with CommandFactory functionality, something we need for an application we are developing. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Test Scenarios with Rule Flows in 5.1.1 Guvnor
Hi all, I had (hopefully) a quick question about trying to test rules in rule flows in Guvnor with Drools 5.1.1. I have a simple 4 step rule flow (Start-RuleGroup1-RuleGroup2-End) with 1 rule in each Rule group. When I set up the test scenario to fire the first rule, which will trigger the second rule, activate RuleGroup1, and run the scenario, it doesn't trigger the RuleFlow and fire the rule. I've also tried activating Start instead, but neither of them trigger the RuleFlow. I know from experience that Rule Flows don't seem to work with 5.0, but with the addition of the entry options, I thought they would with 5.1.1. Am I mistaken? Also, when I look at the Audit Log, I see the Rule Flow activated and deactivated before any of the facts are asserted: BEFORE RULEFLOW GROUP ACTIVATED group:Start[size=0] AFTER RULEFLOW GROUP ACTIVATED group:Start[size=0] BEFORE RULEFLOW GROUP DEACTIVATED group:Start[size=0] AFTER RULEFLOW GROUP DEACTIVATED group:Start[size=0] OBJECT ASSERTED value:com.test.Game@47244724 factId: 1 OBJECT ASSERTED value:com.test.Customer@4c584c58 factId: 2 Could this be part of the problem?

I'm working in Eclipse only right now, but not using DSL for this particular situation (yet). I've manage to make the error go away by removing the package name from drools.package, however, when I attempt to run the code that builds the application to run the rule, it fails to resolve the Object (Fact) used in the rule.

[rules-users] Unable to find implementation for BusinessRuleProvider
Hi,
I've been experimenting with the Guided Rule Editor plug-in in Eclipse.
I've built a Drools Project using the default Hello World sample
application. I've created a new Guided Rule in my project called
GuidedRule.brl and get the associated drools.package with it. The
rule is simple:
WHEN
THEN
System.out.println(Rule has fired);
I build the knowledge base as follows:
private static KnowledgeBase readKnowledgeBase() throws
Exception {
KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newClassPathResource(SampleGuided.drl),
ResourceType.BRL);
KnowledgeBuilderErrors errors = kbuilder.getErrors();
if (errors.size() 0) {
for (KnowledgeBuilderError error: errors) {
System.err.println(error);
}
throw new IllegalArgumentException(Could not
parse knowledge.);
}
KnowledgeBase kbase =
KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
return kbase;
}
The only line changed is adding the resource of type BRL.
When I try to run, I get the following error:
java.lang.RuntimeException: org.drools.compiler.DroolsParserException:

I've tried variations to add the drools.package as a PKG type, I've had
the rules (and package) in both com.sample and /src/main/rules, but I
can't seem to resolve the problem. drools.package has been updated to
include the package name (package com.sample;) and I import the message
class as well (even though it isn't being used currently).
I suspect the issue is simple, but I haven't been able to figure it out.
Any help would be appreciated.

Re: [rules-users] KnowledgeAgent exception while trying to deserialize
Mike, I believe this is the first time we've tried running anything from workstation to server. Essentially what happened was that I did the upgrade of the drools-guvnor.war file and then we fired up the server following the upgrade. I checked out the server environment to see that it was using the new version of Guvnor (i.e. new features, like reporting, etc.) and it checked out fine. I turned it over to my business partners to start building a new rule app. I installed the new Guvnor-standalone to my workstation (based on 5.1.1) and then started building a java application. I used the local copy to with some dummy rules to verify that my eclipse app was talking to the local server correctly, which it was. It wasn't until about 2 weeks ago we tried to switch my eclipse app to talk to the new Guvnor app built by the business partners that we started seeing the problem. Since we were working with a new app, post-update, we never tried to connect prior to the update. The specific error - KnowledgeAgent exception while trying to deserialize KnowledgeDefinitionsPackage - seems to imply an incompatibility between Drools in eclipse and Guvnor from what I've gathered from Google, mailing lists, etc. It is this issue that is leading towards the idea of just exporting the repository, installing the .zip of the Guvnor-standalone I used for my workstation locally to the server, and then importing the repository. I hope that helps answer your questions.

Nice. Firstly, the re-compile\re-package malarkey is the same as Build package on the package information screen (or whatever we want to call that too!) I am suspicious that something somewhere else has not caused the problem: If Guvnor 5.1.1 (presumably) worked OK for a couple of weeks following the upgrade. Was this the first new package created with 5.1.1? Has the server been restored for some reason (to a backup with 5.0.1)? Have any new packages been successful?

Re: [rules-users] StreamCorruptedException - invalid stream
A little more information: - Prior to upgrading the drools-guvnor.war file on the server to 5.1.1 and my local eclipse install of Drools to 5.1.1, I had successfully run from my eclipse to the server many times (using version 5.0.1 on both). - I'm unable to access or utilize the old packages created prior to the upgrade to 5.1.1 (see rules-users Digest vol.49, issue 61 from 12/23 - message 6 attached below) - I CAN run the application locally, using the Guvnor 5.1.1 standalone installed on my computer. This makes me think something is out of synch with the server and my computer. -- Message: 1 Date: Mon, 27 Dec 2010 09:05:50 -0700 From: John Peterson john.peterson.g...@statefarm.com Subject: [rules-users] StreamCorruptedException - invalid stream To: rules-users@lists.jboss.org Message-ID: d3a6e68928c9104bb815c83f43a36bdf0f0c6...@wpscv6nh.opr.statefarm.org Content-Type: text/plain; charset=US-ASCII Workstation Version (windows): 1.6.0_17 Server Version (linux): 1.6.0 (build 1.6.0-b09) Are you using the same JVM version in both machines?

Re: [rules-users] KnowledgeAgent exception while trying to deserialize
I had a ruleflow resource I needed to add, and I cleaned up my KB creation code and that seemed to take care of it. I also did a rebuild of the package in Guvnor, so I'm not 100% sure what exactly fixed it, but it is fixed. Thanks for the follow-up.

that's weird.. you are using a varible that you never define in the Right
Hand Side.
$severity was never defined. In the RHS remember that you can write pure
java. So if you want a variable called severity you should declare it as:
String severity = $patient.
medicalHistoryBleedingRiskFactors.gastritis;

First off, yes, I am an expert Java programmer, not just a Drools expert - yet.
If you took the time to read the post, you would have found that the answer
that was provided to me “DIDN’T WORK”. Never mind, I’ll figure it out myself.

that's weird.. you are using a varible that you never define in the Right Hand
Side.
$severity was never defined. In the RHS remember that you can write pure java.
So if you want a variable called severity you should declare it as:
String severity = $patient.

these same rules in an App Server (GlassFish) I get several rules (about 5)

Pankaj, Try this - go into Guvnor and create a technical rule. Clear out the WHEN-THEN (i.e. make it blank). In the rule editor, type: declare factName @role(event) @expires(5m) end It should validate without any problems. I think this might solve your problem. The other thing I discovered is that the Guided Editor won't support entry-points, but you can use the Technical Editor for it, or you can try to put the verbiage in the DSL translations. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] User Experience with multiple users in Guvnor
I have a question for users out there working with Guvnor. Do you have more than one user working on rules within the same package at the same time? How are you handling versioning and testing, especially if the changes are not going out at the same time? We've been experimenting with Guvnor (5.0.1) and multiple users and we're finding that if user A gets something that parses with an error, it carries over to all the other users when they attempt to validate their rules. This has been confusing because the error is not with their code but with something else completely (like a Function with an error, and they're working on a rule). It seems to us that multiple users working on the same package in Guvnor would require a lot of coordination. Anyone have some wisdom or lessons learned you'd be willing to share? ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Error with update in Guvnor
Hi all,
I'm getting a strange error when I run my rules deployed from Guvnor.
Here's the rule:
WHEN
Fact1 [f1]
Flag1 = false
Flag2 = false
Fact2 [f2]
KeyField = f1.KeyField
THEN
f1.Flag2 = true;
update(f1);
f2.count1 = f2.count1 - 1;
f2.count2 = f2.count2 - 1;
f2.count3 = f2.count3 - 1;
f2.count4 = f2.count4 - 1;
f2.count5 = f2.count5 - 1;
update(f2);
I get the following error in my console when I run:
Exception in readKnowledgeBase: [Error: illegal use of operator:
PROJECT]
[Near : {... Unknown }]
^
[Line: 1, Column: 0]
If I remove the second update, it runs without error (but my rules
dependent on the updated f2 don't work). I'm doing this in the Guided
Editor. I've tried both Modify the values of f2 and doing the update
as free form DRL (update(f2);). As listed above, if I put a print
between the last assignment and the update, I get the print results
before the error. If I put the print last, I never see it, so I'm 99.9%
certain it is choking on my update.
Version Specifics:
- Guvnor 5.0.1
- Drools 5.0.1
- JBoss 4.2.3.GA
Any help/guidance would be appreciated!

[rules-users] Starting a process in Guvnor with ruleflow-group
Hi all,
I'm doing some experimentation for a business problem and I've hit a
snag when it comes to Guvnor and Ruleflow-Groups.
I'm using Guvnor 5.0.1 and Drools 5.0.1.
I've uploaded a simple 4 step (plus start and end) ruleflow-group to
Guvnor. I've added ruleflow-group attributes to all my rules,
associating them to one of the four steps in my ruleflow. My code for
the execution is as follows:
cmds.add(CommandFactory.newInsertElements(recordsToRun));
try {
KnowledgeBase kbase = readKnowledgeBase();
StatelessKnowledgeSession ksession =
kbase.newStatelessKnowledgeSession();
ExecutionResults results =
ksession.execute(CommandFactory.newBatchExecution(cmds));
} catch(Exception e) {
System.out.println(Exception in readKnowledgeBase: +
e.getMessage());
}
I've seen in other documentation that a startProcess is in order (e.g.
ksession.startProcess(ruleflowname)), however, startProcess is not
available for StatelessKnowledgeSession and the process is in Guvnor
already, not locally. I'm guessing it is something simple I've
overlooked, but it isn't clicking for me at this point and my search
online for answers hasn't found one yet. Any suggestions would be
appreciated.
Thanks!

[rules-users] Some rule packages have disappeared in Guvnor
Hey all, We restarted our JBoss Server (version 4.2.3.GA) on Linux and after the restart completed, we noticed that some of our packages (2) have disappeared. I've gone through the server log and there is an error (PathNotFoundException) for one of the missing packages, which I've pasted below. Included in Guvnor is the default package (still present), the mortgages example package (still present), and another working package for testing ideas (also still present). Has anyone seen this type of error before? Also, can someone tell me where these packages are stored in Guvnor so we can verify that the missing package is still out there? Any help would be appreciated.

Re: [rules-users] Is it possible to use CEP features in Guvnor?
I've done some additional experimentation and verified that you can't run Test Scenarios (at least, can't run them successfully). I did discover that I could create a Technical Rule that has the declare to establish our object as an event. I'm sure this isn't intended, but it works For technical rules, adding the from entry-point X is easy. For DSL rules, I can hide it in the translation for the literal values the user can specify For the Guided Rule Editor, it appears that adding Free Form DRL to the LHS of the rule under the Fact block to enter the from entry-point X part as well and it parses and runs okay. jp Date: Tue, 12 Oct 2010 20:50:28 +0100 From: Michael Anstis michael.ans...@gmail.com Subject: Re: [rules-users] Is it possible to use CEP features in Guvnor?

I'm running version 5.0.1 right now. Here's the scenario: I have a Java application loading data (56 records right now) from a flat file, creating objects (one per row), parsing the individual fields on the file into the attributes of the objects, putting them into an array, and then inserting them into my Guvnor session. In Guvnor, I have a POJO model to receive the data plus a Declarative Model that enables the Guvnor user to set derived values based on the input data. There is a very basic rule that says the following (using the Guided Editor): When AppData[ad] Then System.out.println(Creating DerivedValues for + ad.getAwards_id()); /* Added as Free Form DRL Insert DerivedValues appID=ad.getAwards_ID(); System.out.println(DerivedValus for Awards_id + dv.getAwardsID()); /* Added as Free Form DRL Essentially, for each Fact of AppData, I'm creating and linking it to a Fact of DerivedValues that the user can add attributes to. I runs fine for the first 51 rows, then blows up on the rule when it is processing the 52 row (with 4 more to go after that). If I cut the file down to only have 51 rows, it doesn't blow up. The error - java.lang.NoClassDefFoundError: com/statefarm/DerivedValues is confusing because it has used DerivedValues 51 times without issue up to this point.

[rules-users] NoClassDefFoundError when inserting Guvnor-declared Fact
I'm experiencing a stack trace error (which I've pasted below) with a sample Drools/Guvnor application. I'm running version 5.0.1 right now. Here's the scenario: I have a Java application loading data (56 records right now) from a flat file, creating objects (one per row), parsing the individual fields on the file into the attributes of the objects, putting them into an array, and then inserting them into my Guvnor session. In Guvnor, I have a POJO model to receive the data plus a Declarative Model that enables the Guvnor user to set derived values based on the input data. There is a very basic rule that says the following (using the Guided Editor): When AppData[ad] Then System.out.println(Creating DerivedValues for + ad.getAwards_id()); /* Added as Free Form DRL Insert DerivedValues appID=ad.getAwards_ID(); System.out.println(DerivedValus for Awards_id + dv.getAwardsID()); /* Added as Free Form DRL Essentially, for each Fact of AppData, I'm creating and linking it to a Fact of DerivedValues that the user can add attributes to. I runs fine for the first 51 rows, then blows up on the rule when it is processing the 52 row (with 4 more to go after that). If I cut the file down to only have 51 rows, it doesn't blow up. The error - java.lang.NoClassDefFoundError: com/statefarm/DerivedValues is confusing because it has used DerivedValues 51 times without issue up to this point. I've been trying to a handle on this for a couple days without any luck. Here is my stack trace: RuleAgent(default) INFO (Tue Aug 24 11:17:12 CDT 2010): Configuring with newInstance=false, secondsToRefresh=-1 RuleAgent(default) INFO (Tue Aug 24 11:17:12 CDT 2010): Configuring package provider : URLScanner monitoring URLs: http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/com .statefarm/LATEST RuleAgent(default) INFO (Tue Aug 24 11:17:15 CDT 2010): Applying changes to the rulebase.

I prefer using modify rather than update but that is a minor issue.
Your key problem is that your rule fires regardless whether it needs to or
not, you need to write your rule so it only fires when it is valid for the
action to be performed.
In your current rule you seem to be doing a null check against
workflowActorId and then setting workflowId; you probably want to make these
consistent so you do a null check and then set that same property to an
appropriate value.

[rules-users] FW: how to fire a subset of rules in KB?

Hi all,
I'm a newbie for drools.
And i want to know how to fire a subset of rules in KB, suppose there
are three rules named A,B,C, and I want to fire rule A only.
by the way,
suppose there is a drl file containing rule, and i have set up KB, and
call fireAllRules through statefulKnowledgeSession. After that, the rule
file is changed, how to load rules dynamicly?
Is there any solution?
Thanks in advance!
best regards.

Hi,
I'll take a crack at you first question
Check out Agenda Filters:
http://legacy.drools.codehaus.org/Agenda
The example listed is using Rule Names, but you can use the following to
look at Meta Attribute values instead:
AgendaFilter filter = new AgendaFilter() {
@Override
public boolean accept(Activation activation) {
// Filter out rule Hello World from Sample.drl for execution
if (activation.getRule().getMetaAttribute(Purpose).equals(Print
Hello
World)) {
return true;
}
return false;
}
};
On your rules, you'll want to add a meta attribute for groups A, B, and
C. Here's an example:
rule Hello World
@Purpose(Print Hello World)--- THIS IS YOUR META-ATTRIBUTE
when
m : Message( status == Message.HELLO, myMessage :
message )
then
System.out.println( myMessage );
m.setMessage( Goodbye cruel world );
m.setStatus( Message.GOODBYE );
update( m );
end

[rules-users] Working on Selectors - getting 'The Selector named onlyNonDraftRules is not available'
I'm working off of Jarosław Kijanowski's blog post from 7/8/2009 on using Selectors: http://www.kijanowski.eu/index.php?site=articlesarticle=guvnor_selectorslang=en I've followed the instructions for a DRL selector, including adding a line to the selector.properties file as follows: onlyNonDraftRules=/NonDraft.drl Both the NonDraft.drl file and selector.properties file are here: parent directory\jboss-4.2.3.GA\server\default\deploy\drools-guvnor.war\WEB-INF\classes My NonDraft.drl is as follows: package org.drools.guvnor.server.selector import org.drools.repository.AssetItem import org.drools.guvnor.server.selector.Allow rule 'non draft rules' dialect 'mvel' when AssetItem(stateDescription != Draft) then insert(new Allow()); end When I try to do a Build Package in Guvnor, I get the following error: Name: com.sample, Format: package, Message: The Selector named onlyNonDraftRules is not available My package in Guvnor has a few rules, only one of which is not in Draft status. Everything is built in Guvnor (including Facts - no code is written in Eclipse). Has anyone seen this error before and know how to correct it? I'm using 5.0.1. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Using Drools as a glorified Hashmap
Hey Daniel, My suggestion was that a single default rule could be fired to indicate that the prescription was invalid if all the matching rules failed to create a valid match. Example: - Match Rule 1, Salience 50, Activation-group Match Rules - Match Rule 2, Salience 50, Activation-group Match Rules - Match Rule 3, Salience 50, Activation-group Match Rules - Match Rule 4, Salience 50, Activation-group Match Rules - Match Rule 5, Salience 50, Activation-group Match Rules - Match Rule 6, Salience 50, Activation-group Match Rules - Match Rule 7, Salience 50, Activation-group Match Rules - Match Rule 8, Salience 50, Activation-group Match Rules - Match Rule 9, Salience 50, Activation-group Match Rules - No Match Rule 1, Salience 0, Activation-group Match Rules Activation-group allows only one rule to fire from all the rules sharing that activation-group. By putting a positive salience (priority) on all the match rules, if any one of them matches, that's all that can fire per the activation-group. However, if the No Match rule is fired, that means that the prescription was not matched by any of the match rules. It is a default. The rule can be as simple as: Rule No Match salience 0 activation-group Match Rules When Eval(true) // Always true Then Do your no match logic End The activation-group is doing your heavy lifting, so to speak jp Message: 3 Date: Wed, 19 May 2010 06:20:39 -0700 (PDT) From: djb dbrownel...@hotmail.com Subject: Re: [rules-users] Using Drools as a glorified Hashmap To: rules-users@lists.jboss.org Message-ID: 1274275239719-829059.p...@n3.nabble.com Content-Type: text/plain; charset=us-ascii Hi John, Wolfgang, Thanks for your suggestions. Though I didn't use either of your suggestions as described, it helped me work it out. I added tokens describing the prescriptions, then as they are matched (using RETE), the tokens are retracted. Then any tokens left over are invalid. It is probably as fast as a HashMap. I don't think John's solution would have worked, because no single rule can determine whether a prescription is invalid.

Re: [rules-users] Using Drools as a glorified Hashmap
How many match rules do you have? You could always set a single invalid rule with a low salience (at least lower than your match rules) that is always true and sets the flag that it is invalid. Then put all the rules into the same activation-group so that only one can fire. If the invalid flag is set, that means that the 'no match' rule was the only one that could have fired. If it matches, the activation-group will prevent the 'no match' rule from firing -- Message: 3 Date: Tue, 18 May 2010 02:56:21 -0700 (PDT) From: djb dbrownel...@hotmail.com Subject: [rules-users] Using Drools as a glorified Hashmap To: rules-users@lists.jboss.org Message-ID: 1274176581461-825851.p...@n3.nabble.com Content-Type: text/plain; charset=us-ascii Hi Drools users, I've got a situation where I've got a list of Drug codes which can only be used for certain prescription codes. The traditional method for implementing this is to simply pre-load the values in a static Hashmap. Then if get() returns null, it is not a valid combination. O(1), blazingly fast. The issue with using Drools for this, is that Drools can match a code to a code, and mark it as valid, but cannot call it invalid, as another rule may still be relevant. Therefore, using Drools for this would require marking combinations as valid, and afterwards, doing a linear traversal of the prescriptions to see if there are any combinations that are not valid. Is this the case? I would like to try implement it in Drools just for the sake of consistency, but it seems a bit of a hack.

[rules-users] Questions about using Knowledge Agent
Hi all, I'm trying to get the sample code in the Drools 5.0.1 User Manual to work locally for a Knowledge Agent, but I'm missing some info (from my perspective) to get it to run. Question #1: From the User Manual (3.2.6): KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent( MyAgent ); kagent.applyChangeSet( ResourceFactory.newUrlResource( url ) ); KnowledgeBase kbase = kagent.getKnowledgeBase(); In the third line, what is url and how is it defined in the java code? I don't know what to set up here to make it work. I've found this same code on multiple sites, but no answer to the question. Question #2: How do I set up a Change Set XML file? I see the XML, but I don't know where to put the file and how to link it into the code. Question #3: Does KnowledgeAgent replace RuleAgent for invoking Guvnor-deployed packages in 5.0.1? If so, how do you specify the url of the deployed package from Guvnor? Sorry if my questions are ignorant. I've been trying to find these answers for several days and hit the point where I needed to get some help.

Re: [rules-users] rules not wrking
If you really wanted to see your text string there, you might be able to invoke a method that takes that text string and prints it and then returns true in all cases. You'd most likely need to put it in an Eval as suggested below. You can't directly use java code inside the LHS of a rule. You can though use eval to call a java method inside your LHS. Also remember that you don't have to use ; in the patterns. 2010/4/30 Puneet duggal duggalpu...@gmail.com frnds i have a rule and its not working and i for checking i have put a Sop in my when but it not prints the Inside Area_SqFt_1_10-01-09_12-31-14 so how can we put SOP inside when clause. rule Area_SqFt_1_10-01-09_12-31-14 date-effective 01-Oct-2009 date-expires 31-Dec-2014 salience 6 no-loop true when System.out.println(Inside Area_SqFt_1_10-01-09_12-31-14); objectP2483 : Para_2483( (fid2335==Block) (fid2336==16) ); then System.out.println(Area_SqFt_1_10-01-09_12-31-14); objectP2483.setFid31003(new Double(497)); end ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
