Hi,
I'm trying to use change-set.xml, which pionts to a drl file.My code is
try {
url =new URL("file:config/change-set.xml");
} catch (MalformedURLException e) {
e.printStackTrace();
}
kagent = KnowledgeAgentFactory.newKnowledgeAgent( "MyAgent" );
kagent.applyChangeSet( ResourceFactory.newUrlResource( url ) );
kbase = kagent.getKnowledgeBase();
ksession= kbase.newStatefulKnowledgeSession();
sconf
=ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty( "drools.resource.scanner.interval", "10" );
ResourceFactory.getResourceChangeScannerService().configure( sconf );
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
ksession.insert(object);
ksession.fireAllRules();
and my change-set.xml is:-
<?xml version="1.0" encoding="UTF-8"?
<change-set xmlns='http://drools.org/drools-5.0/change-set'
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'
xs:schemaLocation='http://drools.org/drools-5.0/change-set
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/...
<add <resource source
='file:config/Rule.drl' type='DRL'
basicAuthentication='enabled' username='admin'
password='admin'></resource
</add </change-set
This code worked without any exception, but the rule is not executing. I
tried without changeset.xml and rule worked properly.
What is wrong?
Thanks

Could you please attach an DebugKnowledgeAgentEventListener to your agent:
kagent.addEventListener(new DebugKnowledgeAgentEventListener());
and post the output?
I guess you run into the following problem.
kagent has a default to always create a new KnowledgeBase if something
changes. This does NOT modify your kbase reference. If you want to change
the already required kbase you have to set
KnowledgeAgentConfiguration aconf = KnowledgeAgentFactory
.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.newInstance", "false");
KnowledgeAgent kAgent = KnowledgeAgentFactory.newKnowledgeAgent(
"Agent", aconf);
kind regards,
Lukas Stampf

And try removing the authentication from the changeset, its just file access.

Hi,
Thanks for your replay.
I tried the way you said and my rule got executed.But there is some
problems.
1) My rule worked only one time with ' insert(); ' .My rule is
import java.util.List;
import java.util.ArrayList;
rule "Set Art"
no-loop true
when
$object : object()
$Value : Value($th: test, $Type : Type, $Id : Id,$Name : test.Name
,test.Name == "CPU Usage(%)" )
from $metric.metrics
not Art( testSettingId == $testId )
then
System.out.println(" Change-set.xml ");
Art art = new Art();
art.setMetric($Value);
art.setName($Name);
art.setCount(1);
art.setType($Type);
art.setObjectId($Id);
art.setCurrentTimeMillis(System.currentTimeMillis());
insert(art);
retract ($object);
end;
I tried after removing ' insert(art); ' ,then it worked properly.
2)When I changed the rule (System.out.println(" test ");) to test the
scanning interval ,the word 'test' printed more than two times at the same
iteration. The same happens every time the rule modifies.
Can you help me in this'
Thanks.
