Hi,
I would like to ask for help with setting up drools-server with Guvnor. I am using version
5.1.1 of both.
I am trying to set up an instance of drools-server in Tomcat that periodically loads new
updates of packages published in Guvnor (both drools-server and Guvnor run in the same
instance of Tomcat).
My change set definition is as follows:
<?xml version="1.0" encoding="UTF-8"?>
<change-set xmlns='http://drools.org/drools-5.0/change-set'
xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'

of my packages>/LATEST"
type="PKG" basicAuthentication="enabled"
username="<username>" password="" />
</add>
</change-set>
My knowledge-services.xml configuration is as follows (based on the unit test examples
highlighted in
http://article.gmane.org/gmane.comp.java.drools.user/20992/match=drools+s...):
<?xml version="1.0" encoding="UTF-8"?>

</drools:resources>

</beans>
On loading drools-server, the resources listed in the change set are loaded and
available.
The problem is that when a new package built and published in Guvnor, drools-server does
not detect this and update itself. The effect is the same as if a KnowledgeAgent were used
locally and
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
were not called. This leads me to the assumption that drools-server does not start these
services by default.
My question is then can/how do I configure drools-server to start these services such that
it will update new changes from Guvnor automatically?
Thanks a lot for any help you can offer,
Cheers,
Graham.

Hi,
I've also faced the same problem.
Hope somebody could give a hint.

At startup I see that the KnowledgeAgent registers a listener but never
detects changes:

Bumping this thread - I'm actually observing exactly the same behaviour (all
resources are being pulled via http). Anyone got news on this or some advice
how to fix this?
Thanks!
Best,

Which version are you using? In 5.2.0.SNAPSHOT you can create a new session dynamically
each time.
Then use some eviction policy to clean up the unneeded ones.

I'm using 5.1.1.34858 FINAL at the moment...
Is there any documentation or hints on how to achieve this behaviour in
5.2.0? The 5.2.0 SNAPSHOT docu doesn't seem to mention any new features
(yet)...I took
http://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/tr...
as reference...
Thanks,
Best regards,
