Hi
Is it a good approach to apply rules on large data-sets ranging 100,000 to
50 million records Of course it depends upon the logic written in the rule
conditions and consequences.

Thanks, Mark.
Would you please help with my 2nd question, i.e. the best way to monitor
several directories and load DRL files on the fly in Drools 6.0 release?
Best regards.

You should realize that the LHS ("when") and RHS ("then") are different
and use different syntaxes.
The RHS is essentially java... you can't use ":" and "from".
Also.. "Event(..) from .." is a pattern - a filter that tries to match
existing objects asserted in the WM.
What you need there is to cre
Will you please, please, PLEASE have a short look at the Drools
documentation, available just for the effort of reading it? This will
tell you that "accumulate" and "from" are constructs to be used on the
left hand side of a rule and NOT on the right hand side, where (with
the exception of a few ad
i tried this :
rule "new file"
when
FileData($old : fileOld, $new : fileNew, fileOld != fileNew)
$newFile : String( this not memberOf $old ) from $new
then
event : Event("file added", filename, new Date()) from $plus
Event.listOfEvents.add(event);
event.display();
end

"from" will iterate for you, exactly like "accumulate" counted the events.
If you need more details, please consult the documentation

The problem here is even if multiple files are added, there is only one
event object created. i want to have like say if 3 new files are added, 3
event objects must be created, and all three event objects must be added to
List listOfEvents.
Thanks.

The "accumulates" should not be in the "then" part of a rule (see my
previous email).
That rule gave you two lists, in the variables $plus and $mins, that you
can use in the consequence.
If you need to process each file separately, you may want to do
something like this:
rule "new file"

Ok, this should make it happen
1) Add new Guided Rule
2) Tick "Use DSL"
3) Click OK
4) Add a DSL sentence
5) Validated rule - OK
6) Viewed Source - OK
7) Saved - OK
8) Re-opened - OK
*9) Add a "raw DRL" to the "then" clause
10) Save and publish. You should see error in server.log*
restarting jbo
In KModuleBeanFactoryPostProcessor there are statements like
this: configFilePath = getClass().getResource("/").getPath();
which do not necessarily resolve to the path where the rule resources are.
Replacing this code with one that looks for the rule packages location
worked for me.

Initializing references to objects is always a good idea to avoid NPE.

If the list inside Event has never being initialised it will throw a null
point exception.. so you need to make sure that the list
is initialised properly.

Seeing that the list is static you can use the usual way for accessing
a static class member:
Event.listOfEvent.add( ... );
@Mauricio: It's not unusual to maintain a static collection (even
though there may be better ways, esp. with Drools).

Actually, il have to use this List in another class and then print
list after every rule execution cycle.

Can you please elaborate about why do you want to do that? what's the point
of having a list inside of the Event class that will contain the same event?
The "Then" side of the rule is pure java.. so you just do
event.getEvents().add(event);
but I don't see the point of doing that.
