Re: [rules-users] Loop Drools on Multi Element
Using forall isn't so complicated. You can use the simplified form, where
the
condition to be satisfied is written in the pattern selecting the domain.
rule setPriority
when
$order: OrderType( priority != high )
forall ( OrderLineType( quantity 2 ) from $order.lineItem )
then
modify( $order ){ setPriority( high ) }
System.out.println( set to high );
end
This illustrates very nicely the duality (by de Morgan's laws) between
forall and negated existence.
As for efficiency: repeated evaluation of large lists where the elements
aren't facts /may/
slow you down - whether this is a problem depends on other factors.

Re: [rules-users] KnowledgeAgent custom class loader not working for PKG resources
I forgot to mention that you will have to change your code a little bit. Instead of passing a KnowledgeBuilderConfiguration to the agent, you will need to add a configuration option to the KnowledgeAgentConfiguration object your are using: aconf.setProperty(drools.agent.useKBaseClassLoaderForCompiling, true); This way you are telling the agent to use the kbase's internal CL (We may set this as the default value I think). If you want to try my fix, this is what you need to do: - Prerequisites: java 1.5 or grater, maven 3.0.3 or grater and git 1.- $git clone git://github.com/droolsjbpm/drools.git drools (It will download all the sources and place them in drools directory) 2.- Get the fix from my repo. Fortunately, the fix is just one file: https://raw.github.com/esteban-aliverti/drools/61c2110df8c55c67ff532491865b3f28f368e8db/drools-core/src/main/java/org/drools/agent/impl/KnowledgeAgentImpl.java 3.- Replace the file /drools-core/src/main/java/org/drools/agent/impl/KnowledgeAgentImpl.java in your working copy with the file you downloaded in the previous step. 4.- $mvn clean install -DskipTests=true (this will compile everything and install the generated artifacts in your local maven repo) This could take some time. 5.- If in your project you are already using maven, then you just need to update the version of your dependencies to 5.4.0-SNAPSHOT. If you are not using maven, then you need to go to your local repo an get the generated drools-core-5.4.0-SNAPSHOT.jar and use it.

Hi Esteban, According to the tomcat log, guvnor was trying to connect to derby which I don't use, so it might have been caused by a preset condition in guvnor beta2 version? I scrapped my tomcat 6 and tried running it with Tomcat 7, this worked. Thanks.

[rules-users] Yet another Schema question(s)...
Hi, I am configuring a drools server via spring and I need to execute a startup-command (as shown here http://lucazamador.wordpress.com/2010/05/27/drools-server-spring-configuration/). Seems straight forward until I started looking for .xsd files (specifically for http://drools.org/schema/drools-service-spring http://drools.org/schema/drools-service-spring.xsd). Like most drools code examples I find, these namespaces are broken since they are no longer hosted on drools.org. Even in recent books like Drools Developers Cookbook (which I am liking) he uses these invalid schema locationsurg. I'm working offline, so I normally have to poke around github, grepcode, etc etc looking for the files to download. Three questions: 1) Can someone point me to *drools-service-spring.xsd* 2) I see questions about schema location lots of times/places. Is someone on the Drools team looking into fixing this? 3) Why isn't everyone having an issue with this --- what am I missing? Thanks, -J -- View this message in context: http://drools.46999.n3.nabble.com/Yet-another-Schema-question-s-tp3767225p3767225.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

I have a 5.4.0-SNAPSHOT version with your changes built and made the KnowledgeAgentConfiguration change you suggested.

[rules-users] Drools Fusion: updating event duration
Hi all, i am using Drools Fusion in multi sensor data fusion system. I have some rules that generate a new event when some situations occur. But from the other hand, i would like to update the event, when i understand that new sensor observation is referring to the same event. I have my Event clazz with duration field, i try to update it in modify clause, but i have concern about it, because when i use temporal operator (such as before, meets, so on) it seems that Drools manage them as event with duration null. I could post the code too. Bye bye, Matteo. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Drools Fusion: updating event duration
Unfortunately you can't update event durations or timestamp. Events are supposed to represent things that happened and as so, are immutable (other than data enrichment). If an event representation is no longer true, that event has to be retracted. Most common case is when you are dealing with atomic events (like start and end atomic events) that represent a complex event. Usually you will have a rule that correlates the start and end atomic events and creates a complex derived event, retracting the atomic ones. Edson 2012/2/22 Matteo Cusmai cusmaimat...@gmail.com Hi all, i am using Drools Fusion in multi sensor data fusion system. I have some rules that generate a new event when some situations occur. But from the other hand, i would like to update the event, when i understand that new sensor observation is referring to the same event. I have my Event clazz with duration field, i try to update it in modify clause, but i have concern about it, because when i use temporal operator (such as before, meets, so on) it seems that Drools manage them as event with duration null.

Re: [rules-users] Drools Fusion: updating event duration
If your use case somehow has mutable events, you can retract, change the duration and reinsert. The engine uses optimizations for the temporal reasoning that are based on the fact that events should be immutable. That is why the engine resolves the timestamp/duration attributes at insert time and make them immutable.

[rules-users] Loading rules performance problem in 5.4.0.Beta2 compare to 5.0.1
Hi all, I'm planning to upgrade to Drools 5.4.0.Beta2 from 5.0.1. However when testing the performance w.r.t rules loading, 5.4.0.Beta2 is not only much slower (50% slower) but also eats more memory compare to 5.0.1. Is it something expected from 5.4.0.Beta2 to compensate other fixes/features?

[rules-users] Filtering inside the LHS
Hi All, I am seeking some kind of filtering (if statement) inside the LHS. I have the following example rule (note: $attributeFilteredSentences and $cmdescriptor are defined in the extends rule which is not presented): rule choose message sentence example extends attributeFilteredSentences collection when SContextState(state == SContextState.ONE) $sentences: ArrayList() from collect (Sentences.Sentence( descriptor.meanings.meaning == $cmdescriptor.meanings.meaning ) from $attributeFilteredSentences) then logger.info(RULE: entered rule: +drools.getRule().getName()); //some logic. end as can be seen I am filtering sentences based on the meanings, and the meaning collection must be identical as in $cmdescriptor (this is the case when SContextState.ONE) Now to my question: I have cases ((this is the case when SContextState.TWO) where I do not need exact validation but rather superset of (for this I have a supersetOf operator implemented) I would like to avoid duplicating this rule (as I have similar condition in many other rules) and being able to filter once with == and once with supersetOf depending on the SContextState. Any ideas how to do this? Thanks, Hezi ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

The chapter provides high level info on how you sign up, submit issues, submit pull requests, best practice for tests etc. Please provide feedback, or pull requests, for improvements and this will be part of the documentation for the up coming 5.4 release. I placed a built version of the docs temporarily on the following url, for review: http://www.athico.com/Getting_Involved/gettinginvolved.html You can see and edit the src here: https://github.com/droolsjbpm/droolsjbpm-knowledge/blob/master/droolsjbpm-introduction-docs/src/main/docbook/en-US/Chapter-Getting_Involved/Chapter-Getting_Involved.xml Mark ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
