Re: [rules-users] JBoss Rule Trace feature with 5.0
2010/9/19 Kinjal Khandhar kinjal.khand...@gmail.com Hi All, Can anybody help me with Drools Audit Log(Rule Trace) feature. import org.drools.audit.WorkingMemoryFileLogger; WorkingMemoryFileLogger logger = new WorkingMemoryFileLogger( session ); logger.setFileName( event ); ... fireAllrules()... logger.writeToDisk(); Package org.drools.audit.event contains Filter classes; you may pass suitables instances to logger.addFilter() to reduce the volume on the log file. You should probably use an ActivationLogEventFilter permitting the creation and firing of Activations. The former will tell you which conditions were fully evaluated, and the latter which rules were fired. (A WorkingMemoryLogEventFilter permitting nothing will keep WM operations at bay.) Or, you could set up a event listener (implementorg.drools.event.rule.AgendaEventListener), and see org.drools.event.rule for the subinterfaces of ActivationEvent. This saves you the bother of processing the XML log file, and you'll get the Rule information easily enough: ((ActivationEvent)event).getActivation().getRule().getName() and ...getPackageName() Since you'll only need Sets of activations and firings, this approach may be preferable. To learn which rules were never activated, you can access the Knowledge Packages in your Knowledge Base, iterate over the rules and create a set of all rules; subtracting those from the log will give you the required information. -W My goal is to check which rule got executed,in what sequence and which conditions got evaluated and which did not. Any help/pointers greatly appreciated. Thanks in advance.

Re: [rules-users] drools quirks
1) Have a look at the examples; they return OK. You don't say much about
your rules for any further help.
2) DSL would restrict what users could enter.

I just started using drools and this is my first time implementing a
rules engine. Everything has been pretty smooth but I have some
quirks that I am not sure I can live with.
1) for some reason, if I execute the Knowlege session against an
object, the knowlege session never returns. The only way I can get
the ksession to return is to make IF (obj == null) part of the LHS and
make modify($input){setObj(complete)} part of the RHS
This seems like a deficiency since I have users writing their own
rules, I can see them forgetting this requirement. IS their a way to
get the ksession to firerules only once? If so what does that look like?
2) It seems that any code I want can be executed in the RHS. I could
literally execute something like the following in the RHS.
byte[] b= new byte[10]; // Really big memory waste
I also could just start a bunch of threads.
The point is that I am intending to let the users write their own
rules but I can't do that if there are no restrictions on how/what can
be done inside the rules. Any suggestions? Are there sandboxes or
filters I can activate to restrict the RHS?

Re: [rules-users] rules priority
You could consider using a guard condition e.g. rule 1 when not Solved() Your rule 1 then insert new Solved(); end rule 2 when not Solved() Your rule 2 then insert new Solved(); end If you only want one rule per group then have the grouping as a member of the guard condition. I'm not sure if you can cause the processing of activations to abort. 2010/9/20 Nadav Hashimshony nad...@gmail.com Hi Im using drools 5 with Guvnor 5 i set up 30 Technical rules and build a package to be used by my drools-sample application. my probelm is as followed, some rule may conflict, i want to set up a rule order and if one rule is caught then i want the drools to stop and not continue to try other rules. ive use salience but it hasnt really done the trick. example: my rules: rule Rule-01 salience 100 activation-group group1 ...

Re: [rules-users] calling a function from when
A DRL function like this can be used on the LHS (e.g.. inside eval() )
function boolean print (){
System.out.println( print print print );
return true;
}
BUT, depending on where it is called and which Conditional Elements
preceding it happen to match, it may get called or not. This may be
the reason for your print failing to produce output.

This leads me to the assumption that drools-server does not start these services by default.

Might be because spring.schemas in drools-container/drools-spring/src/main/resources/META-INF has not been updated. If I refer to drools-spring.xsd it's solved. -Evert beans xmlns=http://www.springframework.org/schema/beans; xmlns:xsi=http://www.w3.org/2001/XMLSchema-instance; xmlns:context=http://www.springframework.org/schema/context; xmlns:tx=http://www.springframework.org/schema/tx; xmlns:util=http://www.springframework.org/schema/util; xmlns:drools=http://drools.org/schema/drools-spring; xsi:schemaLocation= http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.0.xsd http://drools.org/schema/drools-spring http://drools.org/schema/drools-spring.xsd; -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/Schema-Error-with-Drools-spring-xsd-tp1527960p1529305.html Sent from the Drools - User 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] SAML 2.0 support ?
Hi, I try to find out how good SAML support in Jboss is. I would like to know if any of you as ever succesfully tested JBoss against a certified SAML 2.0 Identity Provider ? Thank you very much.

Re: [rules-users] Schema Error with Drools spring xsd
We do not maintain publicly accessible schemas. So take the xsds from the jar and host them somewhere locally and make the schemaLocation referenec that.

Re: [rules-users] Drools Flow Events Not Working
Hi,
The process instance should automatically be reconnected to the session (=
working memory) when it is reloaded from the database. It is a little
unclear however, from you stacktrace, how you get a reference to your
process instance after it has been restored. Particularly:
org.drools.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent
(WorkflowProcessInstanceImpl.java:346)
at com.my.poc.PocFlowServiceImpl.processFlow(PocFlowServiceImpl.java:120)
Could you share how this PocFlowServiceImpl class gets the process instance
it then tries to signal? Does it retrieve the session from the session? Or
does it keep a reference from before?

Subject: [rules-users] Drools Flow Events Not Working
Hi,
I am using drools flow 5.1.1 with JPA. I want my flow to stop at a certain
point so I use an AND node with one incoming RuleGroup node and one
incoming
Event node. so as AND guarantees that It executes after both of the nodes
are completed. So my flow stops there. Then i load the session from db and
use following to raise an event on the session:
StatefulKnowledgeSession session =
JPAKnowledgeService.loadStatefulKnowledgeSession(9,knowledgeBase, null,
environment);
ProcessInstance p = session.getProcessInstance(9);
System.out.println(Proc Found - + p);
if (p != null p.getState()==ProcessInstance.STATE_ACTIVE)
{
p.signalEvent(Test, vo);
}
But it fails with following exception:
Exception in thread main java.lang.NullPointerException

[rules-users] Complete Solutions Tabu Question
Hello Drools Users. Do Solution objects need to implement equals() and hashCode() methods in order to take advantage of the completeSolutionsTabuSize configuration? I did a little digging through the code and it appears that Solution objects are being compared with their clones (implicitly that is, they are being used as map keys). AbstractTabuAcceptor:87 The documentation mentions that moves need to implement equals and hashCode, but doesn't talk about Solution needing it. Thanks in advance, Steve___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] ksession.dispose() and DroolsSpringJpaManager.dispose()
I have question on kession.dispose(), what is the best place to call this
method?
I have a code where in i call
ksession.startProcess(someprocess, mapParam);
ksession.fireAllRules();
finally{
ksession.dispose();
}
If i invoke the kession.dispose() like the above, I always ended up in No
value bound to the key - Transaction exception.
My understanding is that all the calls to drools should be enclosed in a
transactional unit. I have done that so.
My observation is that DroolsSpringJpaManager.dispose() method is being
invoked due to my call to ksession.dispose() after the transaction has begun
from my app code and right before the transaction.aftercompletioncommit()
call.
I can see a line of code in DroolsJpaManager.dispose() method,
TransactionSynchronizationManager.unbindResource(this.emf) //
entityManagerFactory reference borrowed from application code.
My question is that why the above line of code is necessary in dispose()
method since this.emf is the reference obtained from Application code jpa
manager, since this method unbinded this resource, transaction initiated
from the application code is also trying to unbind the same resource once
everything is completed results to No value found for this key exception.
When i comment out ksession.dispose() call from my app code, it works fine.
At this point, i am not sure when to invoke ksession.dispose() call and why
the TransactionSynchronizationManager.unbindResource(this.emf) being made
in DroolsSpringJpaManager.dispose() on a reference obtained from
JpaTransactionManager ?
