[rules-users] Implementing complex operators in Decision table
I need some help in implementing complex rules in decision table..
Following are the two queries that I need to implement in decision table.
1 --- ((UPPER(PRODUCT_TYPE_CODE) IN ('REO', 'TRM')) OR
(UPPER(INVESTMENT_GROUP_TYPE) = 'EQUITY' AND
deal_ltv_nbi_ext_Debt = .6)) AND
UPPER(PRIMARY_COLLATERAL_TYPE) = 'HOTEL'

Alright ...
After some more investigation and a lot of trial-and-error, I think I found the
problem:
If the class which contains the method filling the enum (in my case the
DroolsEnumHelper class) is also contained in the POJO model, the dropDown seems
to stop working. Further investigation needs to be carried out to confirm this,
but for the moment I am happy J

[rules-users] Check problems of conflicts in the rules
I want to detect the conflict between the rules with Drools Verifier.

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?

Re: [rules-users] [planner] getBestSolution not returning the correct Solution?
1) First, can you turn on environmentMode TRACE and verify that no exceptions are thrown? Then turn it back off. 2) I suspect you have a bug in your Solution's clone() method. To prove that theory, do Solver.addSolverEventListener(...) and output the solution each time the best solution is found. You should see something like this: Object: O00010440201002 : -5 new best solution O00010440201002 Object: O00010440201002 : -5 Object: O00010440201010 : -4 new best solution O00010440201010 Object: O00010440201003 : -5 Object: O00010440201004 : -5 Object: O00010440201011 : -4 Object: O00010440201009 : -1 new best solution O00010440201009 Object: O00010440201004 : -5 Object: O00010440201010 : -4 Object: O00010440201002 : -5 Object: O00010440201003 : -5 Object: O00010440201011 : -4 Object: O00010440201002 : -5 Object: O00010440201003 : -5 Object: O00010440201004 : -5 Object: O00010440201009 : -1 Object: O00010440201011 : -4 Object: O00010440201003 : -5 Object: O00010440201011 : -4 Object: O00010440201004 : -5 then, in the end, the best solution must be equal to the last best solution (unless the clone() method forgets to clone the entities correctly).

Re: [rules-users] How to read DRL files not in resource classpath?
Hi Charles,
The KnowledgeBuilder will build your knowledge based in your resources when:
kbuilder.add(Resource arg0, ResourceType arg1)
The ResourceFactory.newUrlResource, newClassPathResource, or others will
return a Resource instance
kBuilder.add( the resource with ResourceFactory, and ResourceType as
DSL/DRL/CHANGE_SET(xml from guvnor) and others)
you can optionally add a resource with your specific configuration:
kbuilder.add(Resource arg0, ResourceType arg1, ResourceConfiguration arg2)
after finishing to add your resources, you finished to build your knowledge
base and now you can get the instace of the knowledge base doing that:
KnowledgeBase kbase = kbuilder.newKnowledgeBase();
and after get the knowledge packages from knowledgeBuilder to the
knowledgeBase:
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
its good idea to check for errors:
if (kbuilder.hasErrors()) {
System.err.println(kbuilder.getErrors().toString());
System.exit(1);
}
the resources could be written with errors or the mix of Resources could not
match each other.
After that, you have your knowledge base build as a point start to start
your sessions.
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
add your facts, and after fire your rules.
I hope this helps you,
Daniel Souza - Brazil

[rules-users] Trouble using java.util.List.size in constraints in 5.4.0.Final
Hi everyone,
I've tried to go from Drools 5.3.0.Final to 5.4.0.Final and some strange
errors appeared on constraints using the size of a list.
For instance, given the following object:
public class MyObject {
private ListString param = new ArrayListString();
public MyObject() {
super();
}
public ListString getParam() {
return param;
}
public void setParam(ListString param) {
this.param = param;
}
}
This rule:
rule Sample rule
when
MyObject( param.size 0 )
then
System.out.println( Sample rule activated );
end
Provokes the following error:
Unable to Analyse Expression param.size 0:
[Error: Comparison operation requires compatible types. Found class
java.lang.String and class java.lang.Integer]
[Near : {... param.size 0 }]
^ : [Rule name='Sample rule']
This worked very well in Drools 5.3.0.Final.
Is there some configuration specific to Drools 5.4.0.Final that I've missed
in the release notes?
Thanks in advance for your help.
Best,
Alexis

Re: [rules-users] Trouble using java.util.List.size in constraints in 5.4.0.Final
This looks like a bug.
MyObject( param.size 0 ) = incorrect diagnostic
But:
MyObject( param.size() 0 ) =OK
MyObject( param.size == 0 ) =OK
MyObject( param.size != 0 ) =OK

I cannot change the condition except the ordering.. Please tell me how can I

Re: [rules-users] Giving multiple range values in condition of Decision table
Escape the comma in your input values..
Change: ('REO','TRM'),EQUITY, 0.6, HOTEL
TO: ('REO'\,'TRM'), EQUITY, 0.6, HOTEL
The comma is the delimeter between your arguments $1, $2, etc... so just escape
the comma and it will be skipped as a delimeter.

Armand

[rules-users] Is a single StatefulKnowledgeSession with Distributed Memory cache possible?
Hi All, I am working on a banking fraud detection project with Drools Fusion, which will match a transaction against hunreds of rules to check whether the transaction is suspicious. In some rules, I use time-based sliding window to calculate the average transaction amount of an account in the past 3 or 6 months. One possible rule will be as below: rule Single Large Amount Transaction dialect mvel when $account : Account($number : number) $averageAmount : BigDecimal() from accumulate( TransactionCompletedEvent(fromAccountNumber == $account.number, $amount : amount) over window:time(90d) from entry-point TransactionStream, bigDecimalAverage($amount)) $t1 : TransactionCreatedEvent(fromAccountNumber == $account.number, amount $account.creditAmount * 0.5, amount $averageAmount * 3.0) from entry-point TransactionStream then end In such cases, the Fusion Engine will hold TransactionCompletedEvent in its memory for 90 days. And we have about 1 billion Accounts in total, so the TransactionCompletedEvent will be huge, we will very soon run out of memory. I have been blocked here for a long time! Is it possible to distribute a single StatefulKnowledgeSession in multiple JVMs or machines using Distributed Memory cache such as Hazelcast? If yes, could you give me some opinion on the solution? Or is this the problem the Drools Grid project try to handle? Or there are other techonology to handle large numbers of facts or events problem? As far as I know, Drools Grid distribute multilple ksessions on multiple machines in the Grid, each or several kseesions on one node? Is my understandings right?

Re: [rules-users] Is a single StatefulKnowledgeSession with Distributed Memory cache possible?
Hi, Thank you very much for so qucik response. I cannot even believe it! As far as I know, the Fusion engine has to store the event details for sliding windows. Because if an event in the window is expired, the Fusion engine still need this event details to update the accumulate results. So, I think storing the accumulate results for per day could not conform to Fusion's logic.

Re: [rules-users] [planner] getBestSolution not returning the correct Solution?
1. Thank you for pointing out the problem.
This made me look into Solution file and found the different of
getProblemFacts() with Example.
Updated it and now it return the result correctly.
Old implementation for 5.3.0:
public CollectionMaterial getProblemFacts() {
return this.materials;
}
New implementation for 5.4.0:
public Collection? extends Object getProblemFacts() {
List facts = new ArrayList();
facts.addAll( this.materials );
// Do not add the planning entity's (serviceRequests) because that will
be
done automatically
return facts;
}
2. Question about the cloneSolution.
I have 3 properties in my Solution implementation.
ArrayListMaterial materials; // Problem Facts
ArrayListServiceRequest serviceRequests; // Planning Entities
SimpleScore score;
In example, I noticed that Planning Entity is cloned but Problem Facts is
not cloned.
Why problem facts not cloned?
