[rules-users] Deactivate rule automatically activated via KnowledgeAgent
Hi, I want to adminstrate and deploy my rules with Guvnor. The deployment is done with a binary file (.pkg). On my target system, a KnowledgeAgent with defned change-set is running and activates automatically the rules defined in the pkg file. Up to this point everything is fine. How can I now deactivate a rule (remove it from the KnowledgeBase)? Is there a standard mechanism available to undeploy via Guvnor? Or must I deploy a new pkg file, which does not contain the rule to be deactivated? Are rules automatically deactivated, when the pkg file is deleted on the target system? Is this an approach for solution? What is the best way to solve the problem? Thanks a lot for your help! -- View this message in context: http://drools.46999.n3.nabble.com/Deactivate-rule-automatically-activated-via-KnowledgeAgent-tp3925302p3925302.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
[rules-users] Problem with logging using Drools 5.3.0
Hello, I am debugging my drools application with Eclipse. Using Drools runtime 5.1.0 I've got automatically log entries from Drools on the console window. Now I am using the 5.3.0 runtime and no log entries are available. I have defined a log4j.properties and put it in the classpath. As trace level I have defined ALL. Own log entries are produced and shown on the console, but no entries from Drools are shown. Has anybody an idea, what I can do to get the log entries?

Re: [rules-users] Problem with logging using Drools 5.3.0
Thx Ingo for your reply, but logging with KnowledgeRuntimeLogger is not my problem. This works fine. Drools itself uses log4j for logging of its activites. These log entries are very helpful for analyzing, what happens in Drools. For example, I had the following output with the runtime 5.1.0, while creating a new KnowledgeAgent: [2012:04:115 14:04:889:info] ResourceChangeNotification created [2012:04:115 14:04:889:info] ResourceChangeScanner created with default interval=60 [2012:04:115 14:04:889:debug] ResourceChangeNotification monitor added monitor=org.drools.io.impl.ResourceChangeScannerImpl@7f5580 [2012:04:115 14:04:889:debug] KnowledgeAgent building resource map [2012:04:115 14:04:889:info] KnowledgeAgent created, with configuration: monitorChangeSetEvents=true scanResources=true scanDirectories=true newInstance=true [2012:04:115 14:04:889:info] KnowledegAgent has started listening for ChangeSet notifications Using now the runtime 5.3.0 I have no such entries anymore. -- View this message in context: http://drools.46999.n3.nabble.com/Problem-with-logging-using-Drools-5-3-0-tp3934918p3935165.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
Re: [rules-users] Problem with logging using Drools 5.3.0
Thx, Mark for your advice. I use my own implementation of SystemEventListener now, which uses the log4j Logger for logging. This works fine. -- View this message in context: http://drools.46999.n3.nabble.com/Problem-with-logging-using-Drools-5-3-0-tp3934918p3937481.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
[rules-users] Drools Guvnor - validate a rule results in "Unable to Analyse Expression"
Hi folks,
I have defined some rules in Eclipse and tested with JUnit tests and
everything was fine.
Now I defined the rules in Guvnor and while validating I get the following
error:
[CardTrapping] Unable to Analyse Expression Fraud fraud = new
Fraud(Fraud.CARD_TRAPPING, new SSTEvent[] { $event1, $event2, $event3,
$event4 }); fraudControl.handleFraud(fraud);: [Error: expected type:
com.wn.fraud.droolstest.model.SSTEvent; but found:
com.wn.fraud.droolstest.model.SSTEvent] [Near : {... SSTEvent[] { $event1,
$event2, $event3, $event4 }) }] ^ [Line: 1, Column: 70]
I have imported my data model, before creating the rules, therefor for the
type SSTEvent an import is defined. But it seems, that the type SSTEvent
exists with different versions?
I have this problem for each rule, when I'm using the SSTEvent type in the
"then" case.
Here the complete rule defintion:
package com.wn.fraud.droolstest
import com.wn.fraud.droolstest.model.Fraud;
import com.wn.fraud.droolstest.model.FraudControl;
import com.wn.fraud.droolstest.model.SSTEvent;
global FraudControl fraudControl;
rule "CardTrapping"
when
$event1 : SSTEvent ( eventNumber == SSTEvent.CARD_JAMMED ) from
entry-point "device-event-stream"
$event2 : SSTEvent ( this after [ 0s, 30s ] $event1,
eventNumber == SSTEvent.IN_SERVICE,
deviceId == $event1.deviceId,
branchName == $event1.branchName ) from entry-point
"device-event-stream"
$event3 : SSTEvent ( this after [ 0s, 30s ] $event2,
eventNumber == SSTEvent.CARD_JAMMED,
deviceId == $event1.deviceId,
branchName == $event1.branchName ) from entry-point
"device-event-stream"
$event4 : SSTEvent ( this after [ 0s, 30s ] $event3,
eventNumber == SSTEvent.IN_SERVICE,
deviceId == $event1.deviceId,
branchName == $event1.branchName ) from entry-point
"device-event-stream"
then
// inform fraud control
Fraud fraud = new Fraud(Fraud.CARD_TRAPPING, new SSTEvent[] {
$event1, $event2, $event3, $event4 });
fraudControl.handleFraud(fraud);
end
Thx a lot for help!
