Slinding window !
by Hassan
Hi guys,
While trying to understand how slinding window work, I realize that all
exemples are given with "accumulate" or "collect" functions , I din't know
why ??
$a : List() from collect(Event1() over window:time(2s) from entry-point
"point")
// work
Bur why
$a : Event1() over window:time(2s) from entry-point "point")
doesn't work ??!
Thanks,
Youssef AZBAKH

Order of Execution on Messages
by gboro54
We are currently authoring rules using Drools 5.3 and using jBPM 5.2 for
orchestration. The situation we have is as follows: Certain groups of rules
can execute on n number of messages in any order(i.e the order in which the
consequences occur does not matter). The problem comes in later in the
process when those same n messages need to have their consequences happen in
a certain order. Is there a good way to handle this? We have thought about
appending messages to a queue and just operating on one message at a time
however this seems slow. In addition when utilizing jBPM and drools what is
the best way to batch data in and out of the session. I understand starting
a new session is cheap but was hoping there may be a way to have jBPM insert
n records at a time and just continue to read from the db until no more
records are returned.
TIA!

Drools facts using POJO accessor methods error
by aliosha79
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 MyClass {
protected String className = "Class1";
public getClassName(){
return className;
}
public setClassName(String className){
this.className = className
}
}
Now i have to compose a drl file with a rule like this:
when
$Class : MyClass()
eval ($Class.getClassName() == "Class1")
then
System.out.println("ok!!!");
end
This syntax doesn't rise errors BUT doesn't match the real name... no ok
message are printed.
when
$Class : MyClass (getClassName() == "Class1")
then
System.out.println("ok!!!");
end
This syntax raises me a null pointer exception!!!
What's the right syntax?
Can i use the accessor methods building drools facts?
Thanks a lot!
