Hi.
You can configure a Knowledge Agent in Drools-Server using spring. You have
to declare it in knowledge-services.xml config file. You need to do
something like:
<drools:kagent id="kagent1" kbase="kbase1"
new-instance="false">
<drools:resources>
<drools:resource type="DRL"
source="file:/some/path/to/apache-tomcat-7.0.6/webapps/drools-server/WEB-INF/classes/test.drl"/>
<drools:resource type="PKG" source="
http://somehost:8080/droolg-guvnor/.../LATEST"/>
</drools:resources>
</drools:kagent>
For configure the scan interval, you can use:
<drools:resource-change-scanner id="s1" interval="5" />
There are, though, some caveats:
- If you are deploying drools-server in tomcat, then you can't use
classpath resources in the kagent. I have reported this problem today.
- drools-server doesn't start ResourceChangeNotifierService
nor ResourceChangeScannerService automatically. You need to hack some way to
invoke ResourceFactory.getResourceChangeNotifierService().start();
and ResourceFactory.getResourceChangeScannerService().start();. I was
thinking in a Servlet that calls these methods in its init() method.

Hello everybody:
I am taking a look at Drools Integration documentation to understand how
Drools server works and how can be used, and have a doubt concerning, let's
say... 'KnowledgeAgent capabilities'. Does Drools server support on the fly
rule updating as when using KnowledgeAgent to create KnowledgeBase objects?
If it does, where can be configured 'KnowledgeAgent related' properties such
as newInstance or resource scanner interval?
Thank you in advance for your time.
Kind regards,
Manuel Ortiz.
