Hello,
I would like to use type-safe enums in my rules. At the moment I have
situation like this:
public class Country {
private String name;
// getter/setters
}
rule "Country"
when
Country ( name == "USA" )
then
DO SOMETHING
end
I would like to have something
That rule would work if you added a “name” property to Country.
As a general tip on working with countries, always work with their ISO codes,
not their names.
http://en.wikipedia.org/wiki/ISO_3166-1
… ideally the 2-char codes, which are much more commonly used than the 3-char
codes.
Feel free

A simple hint to turn JIT off would help.
Thanks.

Using the same name for a fact class Country and an enum Country
will most certainly not be possible unless you use full class names for
disambiguation.
And, of course, the name property of fact class Country would have to
have the enum type.

Raphael,
the option to disable jitting is in the class PermGenThresholdOption and the
property name is drools.permgenThreshold.
The idea there was that the main problem that jitting could cause is the
PermGen occupation, so we decided to provide an option to set the percentage
of PermGen space th
Thanks Steve for the advice and code! Awesome.

Hi,
I would like to distribute shifts equally among employees based on their

variable for each employee that holds the employment form. How do I make
sure all shifts get distributed equally, so that somebody that works 50% of

Thanks for the hint.
I have looked around for a generic solution of OutOfMemory, native thread,
etc :

It seems actually that Drools uses a thread pool for Jitting and that in my
case the thread pool
thinks it can create an infinity of threads : and it

I really need your help.
I'm writing a DSL file in order to allow my application user to write their

Hello All,
We are trying to migrate from Blaze to Drools Guvnor.
In Blaze Rule Language, we have functions where depending on conditions, we can
call one RuleSet or Decision Table.
Is there any functionality in Drools where I can call rule inside another rule
depending on some conditions. ( Su
Guvnor's Test Scenarios do not provide the means to test arbitrary DRL
(such as functions, queries etc); only rules.
The only real work-around would be to write a dummy rule that invokes the
function and then check that the rule is working as expected.
With kind regards,

Hi Ayon,
I'm not personally familiar with Blaze, but I can tell you that in Drools,
rules are not something that you "call". In Drools, rules are evaluated
whenever the facts in your WorkingMemory change; and the consequences are
executed according to agenda/rule-flow group, and salience settings.
I use something like the following in rules to good effect:
Country( this == Country.USA )

We will be interested in the the Scala and Java DSL. More particularly the

We like to contribute but being a startup I am not sure how much we will be
able to follow through with contributing.

According to Drools 5.5 reference doc "Nullable planning variables are not
supported for construction heuristics in 5.5.x or lower." I cannot config
the planning variable to be null using drools 5.5?
