It's good to know I always use entry points<br><br><div class="gmail_quote">2010/1/10 Edson Tirelli <span dir="ltr"><<a href="mailto:ed.tirelli@gmail.com">ed.tirelli@gmail.com</a>></span><br><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
<br> Not really. The session.insert(...) method will insert the facts/events into the "default" entry point. You don't need to use a named entry point if you don't want to. What makes the engine treat a POJO as an event is the @role(event) metadata in the declare statement.<br>
<br> Regarding the original question, the engine does not explicitly re-order any events/facts. They are processed in the order they are inserted, unless you are using partitions (it seems you are not). If order is important for you, just make sure you insert them in the proper order and make sure the timestamping strategy you are using is adequate.<br>

if you don't put any timestamp fusion will automatically assign the timestamp at the insertion time.<br>I see the problem now. You are probably not using the entry points for events.<br>In your rules you need to add for example:<br>
Alarm() from entry-point "alarmsEntryPoint"<br><br>and then you need to insert the events in:<br><br>ksession.getWorkingMemoryEntryPoint("alarmsEntryPoint").insert(new Alarm());<br><br>that will treat your POJO as event in fusion.<br>
Please read the fusion documentation:<br><a href="http://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-fusion/html_single/index.html#d0e523" target="_blank">http://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-fusion/html_single/index.html#d0e523</a><br>

<tt>Hi Mauricio,<br>
<br>
Of course I did. What about the timestamps , agenda and jobs that were
used in the example , are they necessary ?<br>
<br>
Thanks,<br><font color="#888888">

Guys,<br>
<br>
I am using DROOLS FUSION last version<br>
It is very important for me that events arrive in the order i fire them<br>
, this is a part of the code used for stream mode :<br>

kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());<br>
><br>
> StatefulKnowledgeSession ksession =<br>
> kbase.newStatefulKnowledgeSession();<br>
<br>
after this part I just start inserting Events into the ksession , i.e<br>
ksession.insert(new Event(a)) ...<br>
<br>
does this suffice to make the the engine in stream mode and hence
ordered ?<br>
In the example app , Events were fired as they arrive , but a timestamp<br>
was given , and also agenda and jobs were used.<br>
Is that necessary for the engine to work in stream mode ?<br>
I have a piece of code that gives me different results every time I run<br>
it ?! it is in stream mode , but for some reason the rule either do not<br>
fire , or do not print the output. is there a way to debug into this ?<br>
<br>
thank you .<br>
k-<br>
