[rules-users] Drools templates header arguments
I am working on a project, using templates to generate all my rules. I have
one problem though, I wanna parse my arguments to the template as a
ArrayList, and do somthing like this:
template header
ruleId
args
package dk.prks
import com.poc.entity.Bill;
import com.poc.entity.BillLine;
import com.poc.entity.Description;
import java.util.ArrayList;
template 01
rule @{ruleId}_@{row.rowNumber}
dialect mvel
when
$bill : Bill ($line : lines) and
BillLine( service == @{args.get(0)}, $lineNr : lineNr) from $line and
BillLine( service == @{args.get(1)}, lineNr $lineNr) from $line
then
$bill.setColor(1);
end
end template
However, this is not possible. Furthermore I want to stretch that
performance is an issue, and i want the generated file to only contain the
values from the list, and not make any look ups in the array when running my
rules

Re: [rules-users] Drools templates header arguments
afaik that's not possible.
Basically the templates replace the value for @{param} with param.toString()
(that's why your approach is not working).
Regarding your concerns about performance: the templates are translated into
rules once - afterwards there is no connection between the variables and the
rules in KnowledgeBase.
You could instead write a module that replaces the @{param} fields with values
from your arrayList within your rules (e.g. loading the rules from a file into
string, then use regex or whatever suits you best).
Then just insert the rules somewhat like this:
String myRules = rule test when @{arr[1]}x... then ... ;
String parameterizedRules =MyTemplateBuilder.build(myRules, yourParams);
Reader rdr = new StringReader(parameterizedRules);
kbuilder.add(ResourceFactory.newReaderResource(rdr), ResourceType.DRL);

Re: [rules-users] Drools templates header arguments
If performance is an issue, make sure that the rule doesn't fire repeatedly
or creates some overhead, due to large sizes of Bill.lines and multiple
occurrences of args(0) and args(1) in ascending line order.

Re: [rules-users] Drools 6 Unable to build index of kmodule.xml
Turn it into a maven recognised JAR, manually place a pom.properties in the
JARs META-INF. You don’t need to convert it to a maven project, with a pom.xml
in the source, or build it with maven.
Then look at the build/deploy/utiize example 4.2.5.6. Default KieSession from
File
http://docs.jboss.org/drools/release/6.0.0.Final/drools-docs/html/KIEChapter.html#KIEOverviewSection
pom.properties:
A pom.properties file, located in the archive in
META-INF/maven/${groupId}/${artifactId}/pom.properties
The fiel contents contains 3 lines:
version=${project.version}
groupId=${project.groupId}
artifactId=${project.artifactId}
If your company restricts you from placing a single pom.properties in a jar,
you’ll have to manually build a KieModule at runtime - similar to the old
pragmatic KnowledegBuilder code. See 4.2.5.10. Programaticaly build a
KieModule using Meta Models

[rules-users] drools 5.5 property reactive issue
I am seeing a weird pattern(or at least unexpected one) when running drools
5.5 in property reactive mode. I have to rules such as:
rule Rule 1
when
$order:Order(orderType==A, orderVolume1000)
then
insert(new Charge($order,code1,-.25));
end
rule Rule 2
when
$order:Order(orderType==A)
then
insert(new Charge($order,code2,-.24));
end
rule Set best price
when
$order:Order($id:id, $setCharge:charge)
$charge:Charge(orderId=$id,$setCharge==null ||
chargeAmount$setCharge.chargeAmount)
then
modify($order){setCharge($charge)};
end
If I insert and Order of 1001 I see all 3 activations get created, Rule 2
fires first thus triggering set price rule and the activation of Rule 1 is
cancelled. If I add a @watch(charge) to the end of the rules or set up
salience Rule 1 fires.
Could someone help me understand why the firing of Rule 2 and thus the set
best price rule cause rule 1 to get cancelled without the @watch?

Building with Maven To dynamically update you have two alternatives. you can do it manually or you can do it automated via kie-ci. To do it manually, load the target KieModule into the KieRepository, and on the existing KieContainer call updateToVersion( ReleaseID ).

If performance is an issue, make sure that the rule doesn't fire repeatedly
or creates some overhead, due to large sizes of Bill.lines and multiple
occurrences of args(0) and args(1) in ascending line order.

Re: [rules-users] What is URL for Guvnor REST API in 6.0.0-Final?
6.0 does not have the same REST API as prior versions. All that we expose is basic operations to manipulate Organizational Units, Repositories and Projects; including building and deploying. The GIT backend 6.0 has means we recommend using any git library to clone the repository, perform whatever CRUD operations you require and push back. Documentation has details of the REST methods we support in 6.0.

Re: [rules-users] What is URL for Guvnor REST API in 6.0.0-Final?
The rest api has changed. Depoyment has changed. We don’t have “packages” any
more. We have projects.
http://docs.jboss.org/drools/release/6.0.0.Final/drools-docs/html/wb.WorkbenchIntegration.html#drools.WorkbenchRemoteAPI
/repositories/{repositoryName}/projects/{projectName}/maven/compile
/repositories/{repositoryName}/projects/{projectName}/maven/install
/repositories/{repositoryName}/projects/{projectName}/maven/deploy
Install builds the JAR and places it in the local m2_repo, which is exposed
over http for clients to download. Deploy is used, if you wish to push the
build to external repositories.

Re: [rules-users] What is URL for Guvnor REST API in 6.0.0-Final?
Thanks guys! Here's our use-case/flow. Could you please share your recommendations on our application integration with Guvnor 6.0.0 We have SwitchYard 1.1 applications that are using the kie method to interact with a Drools backend. In this method you point what used to be a 5.5 CHANGE_SET backend and the middleware takes care of the typical sync of change sets with the application so that it have visibility into the rule in its runtime from the guvnor control point. With 6.0.0, as you say, things of change. We would like to continue using the SwitchYard kie interface with 6.0.0. 1. As per (Comment 8 at https://community.jboss.org/thread/234691), it looks like kie integration is much more complex and not clear as to how I would integrate. Is there than an authoritative document that shows the equivalent 6.0.0 flow, so that our application can get visibility into the rules, etc. as it did with 5.5 2. As per the comment about GIT, if git the access API for retrieving packages, is there documentation about how to unmarshall data in git so that we can write some middleware to insert into kie layer in SwitchYard to hit the repo via git? 3. Assuming we are using the guvnor frontend to manage rules, deploy rules, compile assets, etc. We are not looking for APIs to manage functionality. We need the equivalent of REST to get the information about the assests inside the packages/model. For example, in 5.5 there were multiple REST calls where you could specify an asset UUID and get its source code over rest - In the case of BRL rules that source was XML. That XML is what we need. Can you comment on approaches to getting the equivalent data in the new git scenario?

As per the comment about GIT, if git the access API for retrieving packages, is there documentation about how to unmarshall data in git so that we can write some middleware to insert into kie layer in SwitchYard to hit the repo via git? Packages do not exist as a deployable component. There is the source, contained in GIT. There is a JAR published via maven. GIT is just source, the drl etc. Just use standard GIT commands to check it out. You don’t need to marshal it, it’s just source. The JAR is just a jar, that’s published by maven. The local m2_repo is exposed via http url, making it a remotely accessible maven repository. Download the jar, unzip it inspect the contents. 3.

We’ve just found (and fixed) a no-loop bug. https://issues.jboss.org/browse/DROOLS-353 In general we recommend @PropertyReactive over no-loop (and lock-on-active), for best practice. If you hit this bug, which is caused by a modify, and you cannot migrate your stuff to @PropertyReactive you can fall back to using ReteOO mode for your execution. Or use our latest SNAPSHOT builds from master. As mentioned this is fixed and will be in the next binary release - but that will not likely happen until january(guesstimate) now, as our time is focused on preparing the BRMS 6.0 product release.

[rules-users] Drools 5.5.0 - Execution Performance
Hello, first of all I'd like to mention that i am pretty new to Drools, so please be patient :-) We are using Drools 5.5.0. we have a knowledgeBase of about 500 rules and a pretty complex object structure. So far everything is working fine … at the moment we are testing the performance of the engine and we encountered a quite strange thing. We generated about 10 objects, inserted it into the session and measured time needed for execution of rules. To simulate a high number of facts, we inserted the same objects over and over again (100x, 1000x, 1x). When the first objects were inserted, the time of execution was about 100ms but for each iteration the execution got faster and faster (20ms, 10ms and later on even 1ms) .. Now my question: Are the objects somehow cached in the working memory, so that execution gets faster or does this increase of performance has an other reason? I read a few things about shadow facts which are not present anymore since Drools 5 and sync and async Rete and I think this could be a potential answer for my question, but I am not able to understand this completely. For me it is important to know whether the increase of performance is only due to the fact that we are inserting the same facts over and over again or if a significant increase of performance is still possible if facts are not identical? Can someone help me?

Re: [rules-users] Drools 5.5.0 - Execution Performance
You are aware of Java's JIT compilation? Do you retract the facts after each cycle? Is the Working Memory in Identity or Equality assertion mode? Micro-benchmarking Java is tricky. Beware of the Microbenchmark! (Dr Heinz Kabutz, http://www.javaspecialists.eu/archive/Issue124.html) Try to separate the effects by inserting one set of facts until insertion times have stabilized. Of course, Identity without retraction will not tell you anything about the speed of handling assertions with your particular rule set. -W On 25/11/2013, ch3xy igor.stri...@gmail.com wrote: Hello, first of all I'd like to mention that i am pretty new to Drools, so please be patient :-) We are using Drools 5.5.0. we have a knowledgeBase of about 500 rules and a pretty complex object structure.
