The KnowledgeAgentFactory.newKnowledgeAgent(String name, KnowledgeBase kbase) method doesn't initialize the KnowledgeAgent properly ----------------------------------------------------------------------------------------------------------------------------------- Key: JBRULES-1912 URL: https://jira.jboss.org/jira/browse/JBRULES-1912 Project: JBoss Drools Issue Type: Bug Security Level: Public (Everyone can see) Components: drools-api, drools-core Affects Versions: 5.0.0.M4 Reporter: Michal Bali Assignee: Mark Proctor Hi, The KnowledgeAgentFactory.newKnowledgeAgent(String name, KnowledgeBase kbase) method doesn't initialize the KnowledgeAgent properly. The KnowledgeAgentConfiguration is null which causes that the ResourceChangeNotifierImpl is left set to null. The method call fails with following exception: Exception in thread "main" java.lang.NullPointerException at org.drools.agent.impl.KnowledgeAgentImpl.buildResourceMapping(KnowledgeAgentImpl.java:238) at org.drools.agent.impl.KnowledgeAgentImpl.<init>(KnowledgeAgentImpl.java:91) at org.drools.agent.impl.KnowledgeAgentProviderImpl.newKnowledgeAgent(KnowledgeAgentProviderImpl.java:23) at org.drools.agent.KnowledgeAgentFactory.newKnowledgeAgent(KnowledgeAgentFactory.java:66) at droolsbook.integration.agent.Main.main(Main.java:57) Thanks, Michal -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
