Ok... I think I know what is happening..
Background: each element in a package (rule, process, function, etc..)
is mapped to the resource it was defined in. Resources can then be monitored
for changes and the KB will be updated as appropriate.
When the KnowledgeAgent (KA) is created with an initia
Ok so I've added the listeners and I have run 2 scenarios:
1. I do not recreate the KA before I re-run a session, and all the info that
I get even after having deleted a rule from the package is :

What would be the exact use case for this?
The FactType reflective API is used to access the classes declared in DRL
and compiled on-the-fly
at runtime. As long as the jar is on the classpath, you should be fine.
Notice that guvnor is different, since you do have to deliver the jar there.

My fault, I just realized the KA is not using log4j. To enable the logs,
you should do:
// enable scanner and notifier logs before starting them :
SystemEventListenerFactory.setSystemEventListener(new
PrintStreamSystemEventListener());
// enable agent event logs just after creating it :
agent.add
Thank you for the tips! I did change the scanning interval to 20s and I wait
before restarting the session. I have also tried to compile the package
manually in Guvnor after changing a rule but still no effect. The problem is
that I use the embedded editor in my application for creating a rule and

Unfortunately no, there's no way to add **methods** in a rule. There's

Using 5.5.0.Final, I just started trying to use the verifier and get a number
of these exceptions:
org.drools.verifier.visitor.UnknownDescriptionException: Descr ( class
org.drools.lang.descr.ConditionalBranchDescr ) is unknown to drools

Your assumptions are correct, currently @timestamp looks for an
attribute or a getter.
Can you add a long-returning method to your class to perform the
conversion?

I have an object that comes into a stream as an event and I want to use
@timestamp to specify the event time from the object.
Then field that has this information is an XMLGregorianCalendar called
timeStamp. If I specify this attribute with @timestamp(timeStamp) I get and

Thanks, I'll try to reproduce it later. Just a couple of side notes..
Given that the rules fire correctly the first time, I would exclude that the
wrong URL is used. The ChangeScanner has a polling interval of **60**
seconds, so
changes may not be immediate. You can configure that interval, though
Could you post **at least** the unit test throwing the exception,
the one that "enables" it and the code you are using to run them?
This may be yet another blocker for 5.6, so I'd like to investigate it
as soon as possible
Thanks!

At least in latest versions, duplicate rules with the same name are
reported as errors by the KnowledgeBuilder.
I didn't check 5.3, so I wouldn't know for sure about that version.

I have created an example where I import model from a jar file (containing
classes LoanApplication, Applicant, IncomeSource, ...) but get a NPE when I
try to create a object from FactType. That means that packages has not be

Hi,
Is there a way to add a JAR to a knowledgeBuilder with a method like that ?
kbuilder.add(ResourceFactory.newUrlResource("file:///model-1.0-SNAPSHOT.jar"),ResourceType.JAR);
Regard,

Guvnor uses the Drools Verifier module for this. You can run the verifier in
the QA Analysis section.
