if you don't put any timestamp fusion will automatically assign the timestamp at the insertion time.
I see the problem now. You are probably not using the entry points for events.
In your rules you need to add for example:
Alarm() from entry-point "alarmsEntryPoint"

and then you need to insert the events in:

ksession.getWorkingMemoryEntryPoint("alarmsEntryPoint").insert(new Alarm());

that will treat your POJO as event in fusion.
Please read the fusion documentation:

Hi Mauricio,

Of course I did. What about the timestamps , agenda and jobs that were used in the example , are they necessary ?

Thanks,

you need to call ksession.fireAllRules() after: ksession.insert(new Event(a))

Hi Guys,

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

after this part I just start inserting Events into the ksession , i.e
ksession.insert(new Event(a)) ...

does this suffice to make the the engine in stream mode and hence ordered ?
In the example app , Events were fired as they arrive , but a timestamp
was given , and also agenda and jobs were used.
Is that necessary for the engine to work in stream mode ?
I have a piece of code that gives me different results every time I run
it ?! it is in stream mode , but for some reason the rule either do not
fire , or do not print the output. is there a way to debug into this ?

thank you .
