Unable to locate a login configuration
by Klaus Teller
Hi,
Please I need your help on this one. I keep getting the following exception on Tomcat (both 6 and 7) when running Guvnor. I can deploy it without problem, but when I hit the URL (http://localhost:8080/drools-guvnor/) the error message is printed on the Tomcat console and a 500 error message (
500 The call failed on the server; see server log for details) is displayed in the browser.
What am I missing in the installation process?
Thanks,
Klaus.

Re: [rules-users] rules-users Digest, Vol 48, Issue 36
by Dennis Duggan
Thankyou! This was extremely helpful and solved the issue. The manual has very limited information on this. I needed to go through the examples to find it. Also limited information on queries.
Thanks again for your help!

Re: [rules-users] Query query...
by Dennis Duggan
I have a super interface, that both objects implement.
The matching rule looks like:
rule "Match"
when
$oRecord1 : MyObject1( )
$oRecord2 : MyObject2(RefID==$oRecord1. RefID )
then
$oRecord1.setStatus( "Matched" );
$oRecord2.setStatus( "Matched" );
end
I can breakpoint right after running the query and I see objects with all statuses so the matching rule is firing correctly.
Thanks!
Dennis

Subject: Query query...
I have 2 types of objects in my knowledge base that I am trying to equate. Equality is based on a number of different variables contained in the objects. Once I find equal objects I set a status member in each to "Matched", otherwise it will be "OneKnows" or "TwoKnows".
After I fire the rules I use queries that I call from Java code to get the three different types of objects.
query "OneFirmKnows"
oRecord : MyObject1( status=="OneKnows" )
end
query "TwoKnows"
oRecord : MyObject2( status=="TwoKnows" )
end
query "Matched"
oRecord : MyObject1( status=="Matched" )
end
Each query sends back all objects no matter what the status is. The objects have a getStatus( ) method. What am I doing wrong?
Thanks!

Guvnor and oryx designer problems
by melc
Hello everyone,
I have added a sample.bpmn workflow (this is the default eclipse sample with
an extra Script Task printing goodbye to the console before ending) from
eclipse to guvnor, then i tried to edit the sample.bpmn from guvnor using
the oryx designer 1.0.0.026-SNAPSHOT from
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/1.0....
but no diagram is presented. The editor is shown (after removing the
servlet-api*.jar, slf4j*.jar and log4j*.jar (three or four jars in total)
related jars from the designer and placing two of the latest slf4j*1.6.0.jar
as found in guvnor.war into the libs of the jboss AS), but the diagram is
never displayed.
I've tried the following combinations,
- jboss-4.2.3.GA and jboss-5.1.0.GA
- guvnor version 5.1.1 and 5.2.0 SNAPSHOT from
https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/t...
(when tried the 5.2.0 snapshot the editor is not presented at all, I only
get an "Error" dialog stating "Sorry, a technical error occured. Please
contact a system administrator". The corresponding error in the server.log
of the AS is provided at the end of the post. If i ran the editor in its own
tab via localhost:8080/designer/editor?uuid=the id of the asset, the editor
is shown but empty again)
- oryx designer 1.0.0.026-SNAPSHOT
So the question is what is the latest oryx designer version working
correctly with guvnor version 5.1.1 or 5.2.0 snapshot. Is anyone else having
such problems or am I doing something wrong here??
Thanks guys for your time and help.... looking forward to hearing from you.

[Drools Flow] checking Properties of supplied variables in constraints
by Gregor Ryba
Hi,
i am supplying an object as variable to my workflow. in a split i try to check the property "Type" of the
supplied object and according to it move on to the next actionnode (for testing purposes).
in the actionnode i am setting a string, that i am printing out later.
my test looks as follows:
first i supply a ticket with type "reviewer"
after this i supply a ticket with type "developer"
BUT i'm getting the following output:
Output1: processing developer ticket <reviewer>
Output2: processing developer ticket <developer>
so the ticket-object is injected correctly into the workflow, but
i have no clue, why the developer constraint is taken both times
any hints?

Performance monitoring and hotspot detection in rules?
by H.C.
I am trying to implement a performance monitor to find the most problematic
rules in order to optimize performance. The main performance metrics I want
to gather are:
1. How any times a rule's conditions have been evaluated
2. How long each rule's condition evaluation took
3. How many times a rule's then clause actually executed
4. How long execution of a rule's then clause took
Are there any existing or recommended approaches to do this? I have looked
some at the AgendaEventListener methods but can't clearly map events to the
above. Is there some other logging interface with more events?
Thanks in advance.

Drools-flow: Event within foreach throws ClassCastException

Hello,
i'm using the latest version 5.1.1 of drools-flow for a POC project.
I have a process definition where I have an intermediate event node within a foreach CompositeNode.
When I trigger the event using processInstance.signalEvent() I get a ClassCastException:
java.lang.ClassCastException: org.drools.workflow.core.node.CompositeContextNode cannot be cast to org.drools.workflow.core.node.EventNode
at org.drools.workflow.instance.node.EventNodeInstance.getEventNode(EventNodeInstance.java:62)
at org.drools.workflow.instance.node.EventNodeInstance.signalEvent(EventNodeInstance.java:36)
at org.drools.workflow.instance.node.CompositeNodeInstance.signalEvent(CompositeNodeInstance.java:231)
at org.drools.workflow.instance.impl.WorkflowProcessInstanceImpl.signalEvent(WorkflowProcessInstanceImpl.java:357)
at de.bdr.prototype.ProcessTest.main(ProcessTest.java:36)
Many thanks for any help!

Same rules applies twice
by J-C Walmetz
Hi
I use Drools 5.01
I have the following rules:
rule "Reload test" salience 10000
when
$result: Result( $resultId:resultId)
not (exists Test(resultId.technicalId==$resultId.technicalId))
then
Test test = createTest($resultId);
insert(test);
end
When I insert two results with the same identifier, rules is applyed 2 times.
One for each result. I do not understand why.
Do you have an idea of what's happen and how to guratantee that myl rules will
not be applied twice. Here order is not important ...
Thanks
