Re: [rules-users] Help needed in activationCreated and activationCanceled event
Please don't email me direct. I won't reply in the future. All questions and
answers are of value to the community as a whole.
To quote what I replied to an almost identical request a couple of days ago
and posted to the drools-user mailing list.
AFAIK, Activation Cancelled events would trigger in reaction to the
revocation of a logically inserted fact that caused an activation to trigger
in the first place. It would not help identifying which pattern in a rule
was not matched causing your rule not to activate.

- Never fires
Activation created -- Hello World-rule
Hello World
Activation created -- GoodBye-rule
Goodbye cruel world
Rules not executed

this is the same code which you sent me. Never fires is the rule which
never gets executed. we print this from the list of rules we have when we
load the rule file. even if i skip that activation canceled it prints the
same result.

[rules-users] Help needed in Rule flow in Guvnor
Hi, I am using Rule flow in Guvnor for setting some value out of the flow which would be used for my further processing. Below is what I'm trying to achieve, I have two rule groups in the rule flow, out of which the first one would set a key, value pair in a Map which is a field in one of the bean class declared Global for the package when ever each rule is executed in the set of rules in the group and the next rule group would be required to have a set of rules that needs to be executed against this Map which was set in the first rules group and send the final result as output out of the flow. I have defined the rules in the first rule group and set the Map with necessary keys and values, but I was not able to read the Map in this second rule group. I had tried this second rule group as a custom java code in my Java part after the rules execution from guvnor and able to read the map that was set from the first rule group and able set the final decision. I want to know whether reading the Map from the second rule group which was set in the first rule group is possible or not. Or kindly let me know whether I'm missing anything here and needed to add any other logic to achieve the same.

The first pattern of a forall defines the domain, which is: all CreditReport facts; for each object in this domain, the remaining patterns must match; since the FICO pattern merely ascertains the existence of a single FICO chained to a parent CreditReport with validScoreIndicator false, it fires as soon as there is one for each of the existing CreditReports. Jared's solution has the CreditReport CE in front of the forall, unadorned with any quantifier, and the innate behavior of Drools makes sure that the hole thing will be tried, once, for any existing CreditReport anyway. Then, the forall domain is now FICOs with that CR's id and valid == false - but what is the CE? I guess that Drool's behavior is somewhat off the definition, using just FICO() - i.e., all existing FICO objects - as the domain. (However, I think that Edson changed this recently for 5.1.0.) Thus, Jared's rule indeed fires only when all FICOs are linked to the CreditReport are false, but it fails to do so as soon as there is at least one other FICO with either a different parent, or valid. Therefore, to be on the safe side with multiple CreditReport facts and assorted FICO's being in WM at the same time, I propose this rule: rule somerule2 when report: CreditReport( $parentCreditReport_1_Id : myId) forall ( $f : FICO( parentId == $parentCreditReport_1_Id ) FICO( this == $f, validScoreIndicator == false) ) then System.out.println(somerule2 fired on + $parentCreditReport_1_Id ); end Here, the domain is explicitly given as all FICOs of the current CR; and for all of them valid must be false. Still, this solution is not perfect: It would also fire in the absence of any FICO for some CR. To fix this, add a guard against there being no FICOs for the current CR: report: CreditReport( $parentCreditReport_1_Id : myId) exists FICO( parentId == $parentCreditReport_1_Id ) forall ( $f : FICO( parentId == $parentCreditReport_1_Id ) FICO( this == $f, validScoreIndicator == false) ) To complete the picture, one might equally well use the negation of forall, which would have to be propagated into the predicate (read '|' as so that): forall x in D | P(x) = not existst x in D | not P(x) Now the condition delimiting the domain and the negated predicate can be merged again into one CE: rule somerule3 when report: CreditReport( $parentCreditReport_1_Id : myId) exists FiCo( parentId == $parentCreditReport_1_Id ) not ( exists FiCo( parentId == $parentCreditReport_1_Id, validScore == true) ) then System.out.println(somerule3 fired on + $parentCreditReport_1_Id ); end -W On Fri, Nov 6, 2009 at 9:45 PM, Jared Davis sun...@davisprogramming.comwrote: I think this usage may work for your case. rule somerule when report: CreditReport( $parentCreditReport_1_Id : myId) forall ( FICO( parentId == $parentCreditReport_1_Id, validScoreIndicator == false) ) then System.out.print(Fired on + $parentCreditReport_1_Id ); end ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users -- next part -- An HTML attachment was scrubbed...

precompiled binary package into your RE classes.
public void testLoadAndExecBinary() throws Exception {
Person p = new Person();
BinaryRuleBaseLoader loader = new BinaryRuleBaseLoader();
loader.addPackage( this.getClass().getResourceAsStream( /
RepoBinPackage.pkg ) );
RuleBase rb = loader.getRuleBase();
StatelessSession sess = rb.newStatelessSession();
sess.execute( p );
assertEquals(42, p.getAge());
}

You and your team has done a great job.
Micheal I am facing some issue , when I use jbrms.
I have written a sample technical rule by following all the steps
as mentioned in the document.
I am able to download binary package also,but when I tried to use
this package in my rule engine class using following code it’s
giving some error like …
FileInputStream fis = new FileInputStream( C:/drools/
TestPackage.pkg );
ObjectInputStream ois = new ObjectInputStream( fis );
Object objPackage = ois.readObject() ;
when ObjectInputStream object tries to read the object , its
giving some an error
ois.close();
fis.close();
Could you please help me out for this …

Re: [rules-users] Help needed in using working memory logger !
The WorkingMemoryFileLogger creates a list of relevant events (you can use
filters to define which events are relevant for you) and just stores that as
XML in the specified file. This log file is not intended to be used directly
(as it is indeed very complex). The easiest way to see the content of the file
in a user-friendly manner is to use the eclipse IDE and use the audit view to
open the file. This view will then parse the content of the file and show it
in a tree-like structure.
If you would like to personally define how events are written out to a log
file, you can always extend the abstract WorkingMemoryLogger and define how
events should be written out in the logEventCreated(LogEvent) method.
Any contributions to making auditing more configurable are greatly appreciated
! ;)

Dear Kris,
I try to create a filter for my logger, in order to obtain some simple output
(e.g. list modified objects), but the output is still very complex :( . I think
that I did something wrong.
Here is the code:
final WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger(
workingMemory );
logger.setFileName( log/testRules );
ILogEventFilter filter = new ILogEventFilter(){
public boolean acceptEvent(LogEvent event){
if(event.getType()== LogEvent.OBJECT_MODIFIED)
{
logger.logEventCreated(event);
return true;
}
return false;
}
};
logger.addFilter(filter);
logger.writeToDisk();
With kind regards,
Oana

You just need to create a class that implements this interface and that
determines which events should be logged (see the javadoc of the filter and the
working memory logger). See ActivationLogEventFilter and
WorkingMemoryLogEventFilter for an example. You can add your filter to the
logger using the addFilter(ILogEventFilter) method.

Hi everybody,
I try to define an ILogEventFilter on the working memory logger, but I
didn't find anything about how to do this, on the available documentation.
Please help me with some information about the Logger and its
functionality!
With kind regards,
Oana

Hi, I need to know how garbage collection will happen in Drools. Because my system is taking too much time to execute the business logic. Please tell me how to rectify it? One more question I will generate the email content dynamically and send to the client but what will happening is it's taking same content for all mail I think the Last content. For example Through business rule it has generated three mails and it has to send to supervisor then all mail contains last main information like name, Address etc. Please tell me how to rectify it. I need to know how to assert two object of same type and refer then in .drl file. I need to know how to access string array.
