The same code runs fine with
urlResource = (org.drools.io.impl.UrlResource) org.drools.io.ResourceFactory
.newUrlResource(new java.net.URL("http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/OBSP..."));
And resourse type "DRL"
Please find below the source code of the rule
rule "EmployeeMapRule"
no-loop true
enabled true
dialect "mvel"
when
EmployeeMap : EmployeeMap( employeeID : EmployeeID != null , employeeName : EmployeeName != null , employeeCountry : EmployeeCountry in ( "INDIA", "Australia", "USA" ) )
then
EmployeeMap.setEmployeeName( employeeName+" Success" );
EmployeeMap.setEmployeeCountry( employeeCountry );
EmployeeMap.setEmployeeID( employeeID );
update( EmployeeMap );
end
I have written the rule in guvnor.
Drools version 5.5
Please find below the source code for my model employeemap
declare EmployeeMap
EmployeeName: String
EmployeeCountry: String
EmployeeID: Integer
end
I have attached the pojo class I am using to fire the rule

Have you tested that the rules fire when you load them as DRL?
It would probably be worth showing us what EmployeeMap looks like and the rule which you expect to fire if there is an EmployeeMap in working memory.
The Drools version would also be useful.

Problems with the Mrs Manners Benchmark
by Sven Böcherer
Hello,
I am writing my dissertation on BRMS. I want to analyze the performance of
different systems. Drools is one of them.
I installed Drools 6 and wanted to start the Mrs Manners Benchmark for a
first analysis.
Unfortunately if I chose anything else but 5 guests, I get an infinite loop
where the program is never able to find the seating arrangement.
Attached you find a screenshot of what the console looks like.
I really hope you can help me with this problem.
Best regards,
Sven Böcherer

Hi,
I am not able to run rules from .pkg resources.
Knowledgesession is getting populated with package and rules inside the packages but when I am firing ksession.fireAllRules(); no rules are getting executed.
Below is my program
final KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
// Use this line if calling rule defined using guvnor package
org.drools.io.impl.UrlResource urlResource;
try {
urlResource = (org.drools.io.impl.UrlResource) org.drools.io.ResourceFactory
.newUrlResource(new java.net.URL("http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/OBSP..."));
urlResource.setBasicAuthentication("enabled");
urlResource.setUsername("admin");
urlResource.setPassword("admin");
kbuilder.add(urlResource,ResourceType.PKG);
}
catch (MalformedURLException e) {
System.out.println("malformed URL");
e.printStackTrace();
}
catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
// create the knowledge base
KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
// Check the builder for errors
if (kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors().toString() + "********");
throw new RuntimeException("Unable to compile the rule file.");
}else{
System.out.println(".....Rule File is Read Successfully....");
}
// get the compiled packages (which are serializable)
final Collection pkgs = kbuilder
.getKnowledgePackages();
// add the packages to a knowledgebase (deploy the knowledge packages).
// final KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(pkgs);
final StatefulKnowledgeSession ksession = kbase
.newStatefulKnowledgeSession();
ksession.addEventListener(new DebugAgendaEventListener());
ksession.addEventListener(new DebugWorkingMemoryEventListener());
EmployeeMap employeeMap = new EmployeeMap();

Am I doing something wrong? Or has anyone else come across this error?
Any help with this would be gratefully appreciated.

Getting infinite loops even with limitation of fires
by Bojan Janisch
Hello everyone,
Recently I'm using Drools in a multithreaded environment. But after a while I see that Drools is running for endless time even though I gave him with fireAllRules(1000) a limitation to fire only 1000 rules. The occurrence is rule-independent, I've checked multiple times and each time it's another rule which works well if I run it separately.
Could someone check the code of this stack trace? That's a thread dump of my last run.

Also here the rule and code snipped I'm using to prove that the infinite loop does not come from my code:
//kSession is a StatefulKnowledgeSession
try {
//Limiting the Activation will prevent infinite loops
kSession.fireAllRules(1000);
} catch (Exception e) {
System.out.println("error while processing :: " + e.toString());
System.out.println(rule);
} finally {
kSession.dispose();
}
-------------------------------------------------------------------
rule "308"
no-loop
when
$0:NormalizedNamedEntity(
ct_0:CoveredText,
cp_0:Concept,
label_0:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("ops"))
$1:NormalizedNamedEntity(
ct_1:CoveredText,
cp_1:Concept,
label_1:getConcept().getPrefLabel().value,
getConcept().identifierSource.toLowerCase.contains("bodyside"))
then
int start = getStart($0,$1);
int ende = getStop($0,$1);
String attribute = label_0+" "+label_1;
insert(annotate(aJCas, "Operation", 309, attribute, start, ende, "", attribute));
end
I appreciate any help to solve this occurrence.

Replacing an old function in drl
by Sonata
Hi, I want to replace an outdated function defined in a drl file without
touching that file, is this possible? (in 5.5.0)
The java application part that loads the resources cannot be touched as
well. It is configured to read all the drl files from a predefined folder, I
am only allowed to add-in new drl files.
Here are what I have tried:
1. Create a new drl file with the new function with same package name and
same function name
This works *only* if the new file is loaded after the old file.
As I cannot change how the java application loads the resources, I cannot
guarantee the new file is always loaded after the old one, so I tried the
next method.
2. Create a new drl file with the new function with same function name. Add
a rule with high salience and call
drools.getKnowledgeRuntime().getKnowledgeBase().removeFunction("old_package",
"oldFunc");
Function newFunc =
((org.drools.impl.KnowledgeBaseImpl)drools.getKnowledgeRuntime().getKnowledgeBase()).getRuleBase().getPackage("new_package").getFunctions().get("oldFunc");
// a new implementation with the same name
((org.drools.impl.KnowledgeBaseImpl)drools.getKnowledgeRuntime().getKnowledgeBase()).getRuleBase().getPackage("old_package").addFunction(newFunc);
But this didn't work. When the rules are fired, it complains about the
old_package cannot find the function anymore.
Could anyone from the Drools team provide some help on this?
Thanks a lot!

VRP with ExamTimeTabling
by saindofora30
Hi
It is possible to use the example of VRP with the example Exam Timetabling??
Explaining better:
I would like the services that were not performed today could be relocated
on another day. That is, the services could be designated in several days
respecting the deadline.
I would like a guide if it is possible to do this and what would be the best
way to implement this idea.
Thank you.
