[Mario Fusco (JIRA)]

     [ https://issues.jboss.org/browse/DROOLS-2383?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Mario Fusco resolved DROOLS-2383.
---------------------------------
    Resolution: Rejected


You're creating a KieBaseConfiguration enabling the stream mode, but never using it. You should use the method

{code}
kieContainer.newKieBase(String kBaseName, KieBaseConfiguration conf)
{code}

> To me it looks as if the common heartbeat example is broken:
> {code}
> import foo.bar.Heartbeat
> rule "Sound the alarm"
> when
>     $h: Heartbeat( ) from entry-point "MonitoringStream"
>     not( Heartbeat( this != $h, this after[0s,10s] $h ) from entry-point "MonitoringStream" )
> then
>    System.out.println("Sound the alarm");
> end
> {code}
> When running the rule set with:
> {code:java}
> public class Application {
>     public static void main(final String[] args) {
>         final KieServices ks = KieServices.Factory.get();
>         final KieBaseConfiguration config = ks.newKieBaseConfiguration();
>         config.setOption(EventProcessingOption.STREAM);
>         final KieContainer kContainer = ks.getKieClasspathContainer();
>         final KieBase kBase = kContainer.getKieBase("rules");
>         final KieSession kSession = kBase.newKieSession();
>         kSession.getEntryPoint("MonitoringStream").insert(new Heartbeat());
>         kSession.fireUntilHalt();
>     }
> }
> {code}
> Results in:
> {code}

> 11:55:55.820 [main] DEBUG org.drools.core.common.DefaultAgenda - State was INACTIVE is now FIRING_UNTIL_HALT
> Sound the alarm
> 11:55:55.850 [main] DEBUG org.drools.core.common.DefaultAgenda - State was FIRING_UNTIL_HALT is now INACTIVE_ON_FIRING_UNTIL_HALT
> {code}
> Which looks to me as if the alarm gets activated right away instead of 10 seconds after.
