It won't detect changes on the classpath. Needs to be file or http.

Hello,
Any tips on this? I'm seeing this same behavior using Drools 5.1.1:

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

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'
<http://drools.org/drools-5.0/change-set%27>

<http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-api/src/main/resources/change-set-1.0.0.xsd%27>>
<add>
<resource
source='http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/<one
of my packages>/LATEST'
type='PKG' basicAuthentication="enabled"
username="<username>" password="" />
<resource
source="http://localhost:8080/drools-guvnor/org.drools.guvnor.Guvnor/package/<another
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+spring):
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xmlns:drools="http://drools.org/schema/drools-spring";
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd
http://drools.org/schema/drools-spring
http://anonsvn.jboss.org/repos/labs/labs/jbossrules/trunk/drools-container/drools-spring/src/main/resources/org/drools/container/spring/drools-spring-1.0.0.xsd";>
<drools:resource-change-scanner id="s1" interval="5" />
<drools:execution-node id="node1" />
<drools:ksession id="ksession1" type="stateless"
kbase="kbase1" node="node1"/>
<drools:kbase id="kbase1" node="node1" />
<drools:kagent id="kagent1" kbase="kbase1">
<drools:resources>
<drools:resource type="CHANGE_SET"
source="classpath:changeset.xml" />
</drools:resources>
</drools:kagent>
</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.
