Re: [rules-users] How can I know, how many facts are processed by stateFulSession?
Hello,
I think you understood me. Your solution is to validate facts in the rule.
OK - I think this is a good idea, but... What if rules are created by no-IT
(no-Math-aware ;) ) people? I can imagine situation where they do not
validate this issue (div by 0). What then? If I send 1000 facts to ksession,
and 901 has value set to 0? I want my 900 correct facts back. How can I
know, how many have been processed?
P.S. I don't want to use globals to count this.
Thanks,
tom.

I am not sure I understand your problem. The rule clearly should NOT
match facts with value 0, as it will raise division by zero error all the
time. So, the solution, in my mind is:
rule r1
when
p : CTestObj( value != 0 )
then
p.setValue( 1 / p.getValue() );
end
If you need to give a different treatment to objects with value == 0,
just add another rule for them.

Hello,
I have a class and rule:
class CTestObj
{
private double value;
void setValue(double v) {
this.value = v;
}
double getValue() {
return this.value;
}
}
rule r1
when
p : CTestObj
then
p.setValue( 1 / p.getValue() );
end
As you can see, in this rule, there is risk, to put into stateFulSession
object with value set 0. I can't validate this, because, this problem has a
variation where I put into stateFulSession object with set no 0, but the
rule will modify it...
So - I can't validate this = fact with value 0 is correct.
But I process with stateFulSession many, many facts... For example 1000.
And, after 900 facts it occurs, that fact number 901 has value set on 0. In
effect I get an exception: org.drools.runtime.rule.ConsequenceException:
java.lang.ArithmeticException: / by zero. And ksession stops processing
facts. But, 900 facts are processed! I don't want to process them second
time.
And this is my question:
How can I know, which fact is first no-processed fact? Which one stoped
fireAllRules method?
Beacuse I don't want to process them another time.
Greetings :)

Re: [rules-users] Getting rule's body to application.
Hi, I want to ask for another thing connected to my question: am I to use Apache Jackrabbit to solve my problem? I want to get rules body (CONDITION, ACTION, globals definition...) but in Drools I see only classes which contains only rule's name and rule's package. Guvnor does it somehow. As far as I know, it uses Jackrabbit. Is this the only one method?

[rules-users] Grouping of rules in Guvnor GUI
Hi, How can I achieve grouping of rules through Guvnor GUI ? For example, Lets say I have created Rule 1 , Rule 2 , Rule 3 and Rule 4 by using Guvnor GUI only. Now , I want to group Rule 1 and 2 in RuleGrp1 and Rule 3 and 4 in RuleGrp2 using Guvnor GUI only. I have heard about agenda-group in DRL files. But , I don't wish to write this attribute in DRL files(in other words,I want to avoid writing DRL file manually) and then run the RuleGroup. I want this whole process of creating and grouping of rules to be done only using Guvnor , so that I can point to the resulting binary package URL directly in my changeset.xml and start firing rules in my application.

Re: [rules-users] How can I know, how many facts are processed by stateFulSession?
A simple experiment would show you that calling fireUntilHalt() again,
after an exception occurs (in some RHS code) will simply continue with
processing what's left on the agenda.
Of course, the RHS code that throws the exception has only executed
partially, which could easily leave your system in an inconsistent state.
In order to determine which rule and which fact(s), you'd have to
activate event handling and to log the current activation in the
exception handler surrounding fireUntilHalt().

Re: [rules-users] Getting rule's body to application.
I'm not sure if you can decompile a rule to get its sources. When you are using your rules, you are working with a binary representation of them. The RETE algorithm doesn't know anything about the source code. Guvnor uses another language to express rules (when you create them using the guided editor), which is BRL. This is an xml representation of a rule. Guvnor maintain the rules in BRL syntax in Jackrabbit repository. When Guvnor compiles your package, the BRL is translated to DRL and then compiled to PKG. But once the rule is compiled you can't go back. If you have the DRL available, you can use the rule name from the ConsequenceException to search for the source in the DRL. That is all I can imagine. Maybe someone else have a better solution.

Re: [rules-users] Grouping of rules in Guvnor GUI
If rules in different groups are unrelated with each other, you can write them in different packages or build them in different snapshots using custom Selectors. Then, according to the user input, you can create your kbase using just the packages/snapshots you need. If you don't want to create a kbase over and over again, you can create some kind of cache. If the agenda-group solution works for you, but you don't want to modify the generated DRLs, you still can use the Guided Editor (if that is what you call Guvnor UI) to set this attribute to your rules using the show options... link at the bottom of each rule.

[rules-users] Drools Flow - Session objects
Hi, I am writing a small drools flow app. My flow starts off with a RuleGroup node then I've two User Task nodes. What i do is this: StatefulKnowledgeSession session = JPAKnowledgeService.newStatefulKnowledgeSession(knowledgeBase, null, environment); WorkItemManager manager = session.getWorkItemManager(); manager.registerWorkItemHandler(Human Task, new MyWorkItemHandler(false)); MyVO vo = new MyVO(); vo.setComment(These are comments !!); session.insert(vo); ProcessInstance processInstance = session.startProcess(pocflow, null); session.fireAllRules(); session.dispose(); As you can see i am inserting an object of type MyVO into the knowledge base session. I am using JPA to store my flow in db. Now when I execute this code, it starts my flow then calls my drl file for RuleGroup node then calls human tasks etc. In my drl file I've this code: package mypackage import net.plus.kbd.poc.MyVO; rule Displaycomments ruleflow-group display_comments when $vo: MyVO() then System.out.println(Inside Rule-MyVoComments- + $vo.getComment()); end rule NotDisplaycomments ruleflow-group display_comments when not $v: MyVO() then System.out.println(Inside Rule-MyVoComments not found); end So when this rule gets executed it always run NotDisplaycomments rule and prints out that MyVoComments not found. As far as I know it should find my vo which i inserted into the session. isn't it? I am using drools 5.1.1 on jboss 5. Any idea what am I doing wrong?

[rules-users] where to find version 4.2.2GA in svn?
Hello, I purchased a copy of Paul Browne's JBoss Drools Business Rules, and am trying to learn Guvnor via the book's examples. However, they are written for use in drools 4.2.2GA and seem to be incompatible with version 5.1. So, I am going the download and build source route. Browsing the SVN tree, this seems to be the closest tag to a 4.2.2GA version I could find. http://anonsvn.jboss.org/repos/labs/labs/jbossrules/tags/DROOLS_SOA_4_2_18483_GA/ Could someone be so kind as to confirm whether this is the correct tag for that release, or point me in the right direction?

Hi Esteban, I allowed Guvnor to import the built in samples upon first run, so I didn't have to upload any jar files--the rules and models were imported by Guvnor itself. The model is the MortgageModel found in the mortgages package, using the Applicant fact. I originally tried this procedure with the creditRating field, which I now see is a text type. However, it does not seem to work with the age field, which is an integer. Cheers, Alex___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
