Re: [rules-users] KnowledgeAgent to update knowledge base built with Guvnor pkg

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 : // at the beginning [2013-05-02 23:23:32,031:info] ResourceChangeNotification scanner has started [2013-05-02 23:23:32,032:debug] ResourceChangeScanner attempt to scan 2 resources [2013-05-02 23:23:32,033:debug] ResourceChangeScanner thread is waiting for 60 seconds.

I re-create the KA before I run a session, and dispose of the previous KA, and this is what I get without even making any changes to the rules (the same messages stating that the services have started are present but not included): // after disposing of agent [2013-05-02 23:23:50,466:debug] KnowledgeAgent unsubscribing from resource=[ReaderResource resource=null encoding='null'] [2013-05-02 23:23:50,466:debug] ResourceChangeNotification unsubscribing listener=org.drools.agent.impl.KnowledgeAgentImpl@9a8636 to resource=[ReaderResource resource=null encoding='null'] [2013-05-02 23:23:50,467:debug] ResourceChangeScanner unsubcribing notifier=org.drools.io.impl.ResourceChangeNotifierImpl@e171b2 to resource=[ReaderResource resource=null encoding='null'] [2013-05-02 23:23:50,467:debug] ResourceChangeScanner resource=[ReaderResource resource=null encoding='null'] now has no subscribers [2013-05-02 23:23:50,467:debug] KnowledgeAgent unsubscribing from resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] [2013-05-02 23:23:50,467:debug] ResourceChangeNotification unsubscribing listener=org.drools.agent.impl.KnowledgeAgentImpl@9a8636 to resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] [2013-05-02 23:23:50,467:debug] ResourceChangeScanner unsubcribing notifier=org.drools.io.impl.ResourceChangeNotifierImpl@e171b2 to resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] [2013-05-02 23:23:50,467:debug] ResourceChangeScanner resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] now has no subscribers // after re creating the agent [2013-05-02 23:23:50,698:debug] KnowledgeAgent building resource map [2013-05-02 23:23:50,699:debug] KnowledgeAgent no resource mapped for type=TypeDeclaration{typeName='StateEvent', role=FACT, format=POJO, kind=CLASS, nature=DECLARATION} [2013-05-02 23:23:50,699:debug] KnowledgeAgent mapping resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] to KnowledgeDefinition=TypeDeclaration{typeName='StateEvent', role=FACT, format=POJO, kind=CLASS, nature=DECLARATION} [2013-05-02 23:23:50,699:debug] KnowledgeAgent notifier subscribing to resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] [2013-05-02 23:23:50,699:debug] ResourceChangeNotification subscribing listener=org.drools.agent.impl.KnowledgeAgentImpl@1eaa99b to resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] [2013-05-02 23:23:50,698:info] KnowledgeAgent has started listening for ChangeSet notifications [2013-05-02 23:23:50,699:debug] ResourceChangeScanner subcribing notifier=org.drools.io.impl.ResourceChangeNotifierImpl@e171b2 to resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] [2013-05-02 23:23:50,699:debug] KnowledgeAgent mapping resource=[ClassPathResource path='ruleFiles/BasicWithFacts.drl'] to KnowledgeDefinition=[Rule name=sensor has reading value, agendaGroup=MAIN, salience=12, no-loop=true] [2013-05-02 23:23:50,699:warning] KnowledgeAgent: impossible to add a map for a null resource! skiping.

I do not understand what I might be doing wrong in this case or how to fix this since the rules are actually included in the knowledge base.
