Hi,
How can I delete records using rules??
I want to fire my rules on a dataset - modify the dataset and delete data not concerned to me after the modification.

Thanks

Re: [rules-users] Uploading rules dynamically
by Fnu Mahalakshmi
Hi,
I was just going through how to work with knowledge builder and have some doubts:
Code sample is as follows:
final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
// this will parse and compile in one step
kbuilder.add(ResourceFactory.newClassPathResource("HelloWorld.drl",
HelloWorldExample.class), ResourceType.DRL);
// Check the builder for errors
if (kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors().toString());
throw new RuntimeException("Unable to compile \"HelloWorld.drl\".");
}
// get the compiled packages (which are serializable)
final Collection<KnowledgePackage> pkgs = kbuilder.getKnowledgePackages();
// add the packages to a knowledgebase (deploy the knowledge packages).
final KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(pkgs);
final StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
In the above code: I am manually having to add the .drl file and the classpath to my kbuilder. So don't I just have to end up listing all the files and adding it to my knowledge builder?
Is it that each of the files keeps getting added as and when you update the rule files?
How does the program detect this update?? As I am ending up having to add everything.
Please guide.
Thank you
M

Re: [rules-users] Dynamic rule file uploading
by Fnu Mahalakshmi
Hi,
Thanks for the quick reply.
But even by using knowledge agent I have to keep specifying each of the files one by one right? Which ever is contained in my folder with all the rule files? As I would keep doing:
kbuilder.add( ResourceFactory.newUrlResource( "file://myrules.drl" ),
ResourceType.DRL);
So again I would have to list all my files and pass it to the knowledge agent which would add the new rule to the existing package( created using package builder).
Am I going wrong here??
Please help.
Thank you.
M

Dynamic rule file uploading
by Fnu Mahalakshmi
Hi guys,
I have : {R1.drl,R2.drl,R3.brl}
After conversion and loading I have {R1.drl,R2.drl,R3.brl,R3.drl} files in the same directory where all my rules are stored.
I am using:
File folder = new File("SRC/MAIN/RULES");
File[] listOfFiles = folder.listFiles();
for listing all the files in my rules directory.
Now is there anyway that I can just hold on to the required files whenever my rule files are updated rather than having to manually keeping deleting and updating my rules directory?
Is there a more better way to do it rather than just listing all the files in the directory??
Thanks,
M

rule "Rule3"

when

then
a.setModified( true );
update( a );
end
because, modified will never be equal to "false" in your file cause it"s a String

Hi guys,
I have few .drl rules and 1 .brl rule (which I converted into a .drl rule as guided by the documentation online)
All my rules get created and fired. But the converted .brl rule does not get executed only.
I am unable to understand why.
Anyway I can check how it is working??
I put in the most basic rule which should work:
The coverted .drl file looks like this:
rule "Rule3"
dialect "mvel"
when
a : A( modified == "false" )
then
a.setModified( true );
update( a );
end
// A being my fact with attribute modified set to false in the beginning.
The import statements are in a rule.package in the same folder.
Please help me. I do not understand why this rule doesn't get executed. All others do!
Thanks
M

Subject: Drools 5.1.0.M2 - WorkItemNodeInstance -- Listeners can't get hold of WorkItem object
Hi,
There is a change done in Drools 5.1.0.M2 - org.drools.workflow.instance.node.WorkItemNodeInstance class in the method
public void triggerCompleted(WorkItem workItem) at line 196 which is setting the workItemId as -1
this.workItemId = -1;
Due to the above change the listeners which are attached to the "complete" event of the work item - such as the method below
public void beforeNodeLeft(ProcessNodeLeftEvent event) are not able to get hold of the associated workitem object as it returns null.
Is there any specific reason that workItemId is set to -1 even before the associated listeners get triggered or is this a bug?
If it was an intended change then how do I get hold of the "WorkItem" object in the attached listeners.
Thanks
Vijay
p.s This change was not there in the snapshot of 18th April 2010 which I was earlier working on. Above is the only change in this class from the snapshot of 18th April and 5.1.0.M2

Hi,
Thanks for the quick response.
I sent you the converted .drl file.
It gets set like that automatically after conversion.
I just include false in the literal field not "false".
How else could I specify that?
Thanks
