Hi I am getting the following error while inserting into the entrypoint.
rule "Check if EligibleAlert is an Signature Event"
agenda-group "enrichment"
auto-focus true
no-loop true
when
$list : EventSignatureList();
$p : EligibleAlert($a : alert, $a.eventSignatureProcessingStatus!="TRUE"
);
eval((ifMatchesSyslog($list.getAllSyslogMnemonics(), $a)!=null) )
then
try{
WorkingMemoryEntryPoint eventsignaturestream =
drools.getEntryPoint("EVENT SIGNATURE STREAM") ;
eventsignaturestream.insert($p);
} catch(Exception e)
{
log.error("[EventSignatureRules] - exception in Check if
EligibleAlert is an Signature Event alert[ids=" + $p.getAlert().getId() +
"][error:" + e.toString() + "]");
}
end
And I am creating the session this way:
*
knowledgeBaseConfig =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
knowledgeBaseConfig.setOption( EventProcessingOption.STREAM );
kBase = KnowledgeBaseFactory.newKnowledgeBase( knowledgeBaseConfig
);
kBase.addKnowledgePackages(knowledgeBuilder.getKnowledgePackages());
KnowledgeSessionConfiguration knowledgeSessionConfig =
KnowledgeBaseFactory.newKnowledgeSessionConfiguration();
((SessionConfiguration) knowledgeSessionConfig).setClockType(
ClockType.REALTIME_CLOCK );
kBase.newStatefulKnowledgeSession(knowledgeSessionConfig,null);*
I get the Following error when my rule fires:
