This is an MVEL issue, which doesn't have a lexer and doesn't use
antlr. MVEL just picks up characters from a stream, trying to compact
them into tokens, apparently according to some state, in highly
brittle code. (I'm not slandering - the author's comment says so, too.)
I cannot reproduce the bug
@Davide,
there is *nothing* in Drools that is a full-fledged replacement for eitherr

Hello,
I did all the suggestions from Geoffrey (thanks sir) and now the TRACE is

If you think of how RETE works, Globals serve as constants at runtime.
If you need compile-time "constants", you might consider rule templates
instead

Maybe you would be better off leveraging Guvnor for the Rules Editing. Then
you would just need to develop a hook that calls JAXB to take an XML Schema to
a Pojo Object Model within the Guvnor system.

Hi Olfa,
Eclipse indigo is an authoring environment, there's no "deployment" there,
you just need to install the drools plugin from the jboss tools (see docs),
create a rule project and include the tohu jars/rule files in the classpath.
Once you're ready with your application, you can generate e.
Now this is an interesting use case could you please provide more details
on why you're trying to do such a thing? Are you working on some kind of

Hi,
Exactly ! But when I want to test if the sliding windows work in both
cases (with end without Stream Mode), It doesn't work !!
for exemple:
"this is my rule"
rule "sliding windows"
when
$a : Event1() over window:time(2s)
then
System.out.println(
Thanks Laune,
works

If you are not using sliding windows and you are not expecting a retraction
of your not relevant events, it will work.

As soon as you use eval(), you are in Java-land where String
comparisons should not be made using "==".
There's nothing wrong with the second form, i.e., you can write (using
Drools 5.3.0)
MyClass (getClassName() == "Class1")
although the simpler form is usually preferred:
MyClass( classNa
All events have a timestamp.

Hi
I think that yo have to instanciate the object and insert it into the
working memory then you fire all rules like this :
MyClass x= new MyClass();
ksession.insert(x);
ksession.fireAllRules();
it will work without problem
Hi,
i have some troubles to undestand how drools processes FACTS. I have a POJO
class resulted from an UnMarshal jaxb processing like this:

}
public setClassName(String className){

Hi salaboy ,
Thank for your reply,
from the docs:

for instance:
There is no notion of time. No requirements clock synchronization.
There is no requirement on event ordering. The engine looks at the events as
an unnorde

Sure, my clone method is virtually the same as your TSP one
Hi,
What exactly are you doing with events? I think that the temporal operators
will work as expected. If you are working in cloud mode you will not have
sliding windows, the concept of now and events lifecycle managements as
stated in the docs.

Hello,
It's clair that to work with thae events we have to put our base
configuration into STREAM mode like this:

KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
config.setOption( EventProcessingOption.STREAM );/*
But in an exemple, I didn't use this
