Examples of StatefulKnowledgeSession

org.drools.runtime.StatefulKnowledgeSession
a global hibernate session, that can be used for DB interactions in the rules. for( Object fact : facts ) { ksession.insert( fact ); } ksession.fireAllRules(); // this will now execute and will be able to resolve the "hbnSession" identifier. ksession.dispose();
Like StatelessKnowledgeSession this also implements CommandExecutor which can be used to script a StatefulKnowledgeSession. See CommandExecutor for more details.
