I have this test case

KnowledgeBase knowledgeBase =
KnowledgeBaseFactory.newKnowledgeBase(configuration);
knowledgeBase.addKnowledgePackages(kb.getKnowledgePackages());
session = knowledgeBase.newStatefulKnowledgeSession();
TrackingProcessEventListener trackingprocel = new
TrackingProcessEventListener();
session.addEventListener(trackingprocel);
session.getWorkItemManager().registerWorkItemHandler("ETLGroup", new
ETLGroupWorkItemHandler());
WorkflowLoader wrkflwLdr = new WorkflowLoader();
etlGroup = wrkflwLdr.loadETLGroup("etlGroup",
"/home/david/workspace/EDMEngine/META-INF/content.xml");
}
@Test
public void testSessionRun() {
Map<String, Object> parameterMap = new HashMap<String, Object>();
parameterMap.put("ETLGroup", etlGroup);
session.insert(etlGroup);
ProcessInstance processInstance = session.startProcess("Test", parameterMap);
session.insert(processInstance);
session.fireAllRules();
}
I have this work item handler
public class ETLGroupWorkItemHandler implements WorkItemHandler {
private ETLGroupService service = null;
@Override
public void executeWorkItem(WorkItem workItem, WorkItemManager manager) {
ETLGroup etlGrp = (ETLGroup) workItem.getParameter("ETLGroup");
...
etlGroup in the @Before section is not null but etlGrp is always null? I must
have missed something, but cannot see what it is. Can someone point it out to
me?
Thx.

Support for Drools Guvnor / Expert in Latin America
by Miguel Fernando Cabrera
Hello to all,
In my company (an insurance company in Colombia) and we are evaluating
various BRMS.
We have been testing iLog JRules and now we are evaluating Drools
Expert/Guvnor (or JBoss BRMS).
As I am an open source guy, I want to use Drools. As we use a lot of
open source libraries right now (like CXF) is easy for me to use the BRE as
a library.
However, when planning to use a full BRMS like Guvnor, we will need someone
to install and support it.
The obvious choice would be Red Hat / JBoss, However we have tried to
contact sales department but it has been impossible to get an aswer from
them.
So, my question is, Does Anyone know a company (could be the states or south
america) willing to provide the installation and support services for the
BRMS and the maybe the BRE ?
I really appreciate any help on the matter.

Using an array column header in Drools Template
by sk
I am given a list of strings (Comma separated) as input and I need to check
if any of the strings satisfy a given condition. I am trying to implement it
using Drools Rule template with an array column header of unknown size.
To be more specific I need to be be able to generalize the below Template to
include any number of names in the eval statement.
The idea is to give any number of names as input and check if any of the
names satisy the condition given in the template.
template header
name[]
package gms.drools.templates;
global java.util.Map nameMap;
import java.util.Map;
template "RuleTemplate_name"
rule "rule_name"
when
//Generalize the below line to check if the nameMap contains any of the
names given in the input //eval(nameMap.containsKey("@{name1}") ||
nameMap.containsKey("@{name2}") || nameMap.containsKey("@{name3}") ||
nameMap.containsKey("@{name4}"))
then
System.out.println("SUCCESS");
end
end template
Please let me know if anyone has a solution for this or any other
suggestions.

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?
