Hi,
I've set up a knowledge agent the change set configuration. While
running the application I'm changing the rules file and the agent
detects the change and rebuidls the knowledge base. But after that the
output that should have changed didn't change.
Thank you! :)
Greetings
Tina
Here are the code snippets:
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent("AITS CEP Engine Agent");
kagent.applyChangeSet(ResourceFactory.newClassPathResource("changeset.xml"));
KnowledgeBase knowledgeBase = kagent.getKnowledgeBase();
session = knowledgeBase.newStatefulKnowledgeSession();
<change-set xmlns='http://drools.org/drools-5.0/change-set'
xmlns:xs='http://www.w3.org/2001/XMSchema-instance'
xs:schmeaLocation='http://drools.org/drools-5.0/change-setdrools-chan...
<add>
<resource source='classpath:testRule.drl' type='DRL' />
</add>
</change-set>
