[rules-users] java.lang.OutOfMemoryError: Java heap space

[Mahadevappa, Shobha]

Is there anything that has to be taken care in case of a stateless session.
I have a huge collection of facts that needs to get into the working memory and I fire ksession.execute(<Collecton object>);

Just repeat this, as often as required, with as many facts in "facts"
as you want:

// copy-pasted from the API documentation ;-) StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
 for( Object fact : facts ) {
     ksession.insert( fact );
 }
 ksession.fireAllRules();
 ksession.dispose();
