[rules-users] Temporal reasoning with external persistence not working
I am trying to use an external storage for loading and persisting objects.
But when I try a set a temporal reasoning rule it start to fail. The rule,
test code and exception are given below. Please help
// rules file

end
rule test
dialect java
when
$c1:Contest() from session.getContestByName(Contest1)
User(this after[0,3m] $c1) from session.getUserByIndex(0)
then
System.out.println(rule fired);
end
// code
public class Test {
public static void main(String[] args) throws Exception {
KnowledgeBaseConfiguration config =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
config.setOption( EventProcessingOption.STREAM );
KnowledgeBase k = init(); // read and compile rules done here
final StatefulKnowledgeSession ksession =
k.newStatefulKnowledgeSession();
ExternalStorage session = new ExternalStorage();
ksession.setGlobal(session, session);

[rules-users] Class not found Exception dynamically loadind DRLs
Hi there, we try to load small rule packages containing java classes to be provided as globals and drl-definitions from a webserver using an URLClassloader. the globalsclasses could be read and their tests are ok, but as soon as a drl-file is loded which references souch a dynamically loaded globals2 class, a class no found-Exception is fired. That could be expaned with the differenz class loaders used - the URLClassloader for loading the globals-Classes and the standard class loader used to load the drl-files via kbuilder.add( resourceFactory.newUrlResource(url), ResourceType.DRL); Is there any solution for this problem.

[rules-users] Fact Types and Processes not found in package after upgrading Guvnor / Drools to 5.2.0.Final and JBPM to 5.1.0.Final
The project I am working on is using JBPM 5.1.0.M1 and Guvnor / Drools 5.2.0.M2. We are using guvnor to house our business rules, fact types, and business processes, and pull those down to our application using a knowledge agent. When using the versions mentioned above everything works fine, but once I upgrade JBPM to 5.1.0.Final and Guvnor / Drools to 5.2.0.Final, my application is no longer able to find my fact type or processes that are in the package. After I upgrade Guvnor to 5.2.0.Final and rebuild all of my packages, which work fine, and if I manually download the package and open it in notepad, I can see the process and fact type names in the package, but as I mentioned when I load the package through the knowledge agent, my processes and fact types are not available to me. Thanks in advance for any help that is provided. -- View this message in context: http://drools.46999.n3.nabble.com/Fact-Types-and-Processes-not-found-in-package-after-upgrading-Guvnor-Drools-to-5-2-0-Final-and-JBPM-l-tp3159015p3159015.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] Starting Guvnor in Eclipse
Hi all, any Eclipse users around here? I have followed the instructions here: https://github.com/droolsjbpm/droolsjbpm-build-bootstrap/blob/master/README.md for Eclipse Helios+EGit+m2eclipse. I downloaded 5.2.0.Final from https://github.com/droolsjbpm/guvnor.git, imported all Maven projects it could find in the directory (except guvnor-docs which misses something and I didn't care). The Guvnor application will start in development mode, but: - Firefox is causing often 100% CPU with it (might be the development mode) - Eclipse Development Mode view shows LOTS of errors like this: [ERROR] [org.drools.guvnor.Guvnor] - Errors in 'file:/C:/PocDev/GitHome/git/guvnor/droolsjbpm-ide-common/src/test/java/org/drools/ide/common/client/modeldriven/SuggestionCompletionEngineTest.java' [ERROR] [org.drools.guvnor.Guvnor] - Line 47: No source code is available for type org.drools.ide.common.server.rules.SuggestionCompletionLoader; did you forget to inherit a required module?

Again, one can work also like this but seeing hundreds of errors is not helping at all when I try to tinker with something somewhere. Plus there's the 100% CPU thing... where and what should I inherit more than Maven is configured already to inherit? Tinkering around: - I set all other projects as dependencies - I set to export all sources from all projects (but there it bitches also about missing java.util sources, who cares about these?)... - added all these sources to the run configuration nothing changed, I still have the above errors from both system libraries AND project dependencies.

Re: [rules-users] Starting Guvnor in Eclipse
If I am not mistaken you have created a launch configuration in Eclipse for Guvnor (nothing wrong there, I do the same). What you need to do is manually delete all references to test resources in the launch configuration classpath. The apparant lock-up is GWT compliling JScript from the Java code. It can be made quicker by:- * Ensuring no test resources are on the lanch configuration (which will also remove the errors) * Using the FastCompiledGuvnor module (which only compiles for en_US and Firefox - gecko1_8).

[rules-users] AgendaGroup and AgendaFilter
Hi,
Previous Code from drools 3.x:
Below is an example of overridden method in a class that implemented
org.drools.spi.AgendaFilter
public boolean accept(Activation activation) {
boolean evaluateRule = false;
String agendaGroup = activation.getRule().getAgendaGroup();
if (functionalArea.equalsIgnoreCase(agendaGroup) {
evaluateRule = true;
}
return evaluateRule;
}
Drools 5.x
Now I have changed the implementation to
org.drools.runtime.rule.AgendaFilter
How do I re-write the bold-italic line inside the method when variable
activation is now an instance of org.drools.runtime.rule.Activation;
It doesn't support activation.getRule().getAgendaGroup();
Thanks,
saleem

How do I re-write the bold-italic line inside the method when variable
activation is now an instance of *org.drools.runtime.rule.Activation;*
It doesn't support */activation.getRule().getAgendaGroup();/*
We have no made those public yet. We've kept Rule, like much of -api,
minimal. rule groups in general need a rethink and I don't want to
bloat the api. What you can do for now is cast to org.drools.rule.Rule
to get that information, just remember that it's a deprecated class and
can be changed on any release.
Mark

[rules-users] Any suggestions to implement exclusions and avoid update
Hi,
Below are 2 rules, rule1 has higher precedence than rule2. Rule2 should not
execute if Rule 1 executes.
1) One way to get this working is to check the null value.
2) If the update is not called, the Rule2 gets executed using the previous
null value of potentialTheftRating.
Is there any other way to implement this requirement.
rule Rule 1 PotentialTheft0
ruleflow-group TheftRating0
salience 10
no-loop
lock-on-active
when
$client : Client()
$policy : Service(productType == Vehicle Insurance) from
$client.service
$car : Vehicle(potentialTheftRating == null, vehicleType ==
vehicleTypeType.CAR, convertible == Boolean.TRUE) from $policy.vehicle
then
modify ($car) {
setPotentialTheftRating( potentialTheftRatingType.HIGH )
}
update($client);
end
rule Rule2 PotentialTheft0
ruleflow-group TheftRating0
no-loop
lock-on-active
when
$client : Client()
$policy : Service(productType == Vehicle Insurance) from
$client.service
$car : Vehicle(potentialTheftRating == null,vehicleType ==
vehicleTypeType.CAR, price = 2, price = 45000, highTheftProbabilty ==
Boolean.FALSE ) from $policy.vehicle
then
modify ($car) {
setPotentialTheftRating( potentialTheftRatingType.MODERATE )
}
update($client);
end
