The easiest suggestion would be to store DRL in your database ;)
These is a (dieing) BRL XML format but I believe its use is discouraged (as
it's essentially an XStream output of a object model).
You could also look at writing a persistence layer over FactModel which is
the foregoing object model
Well, if it can work that way it should. I'd say open a JIRA and request that
feature. It works with the "principle of least confusion." :)

Hi All,
I am new to this Drool rule ingine use.
Normal drl is working for me.
But mu requirement is i need to configure all the rules in Data base and
from there i need to inject to the Rule engine.This is beacuse Rules can be
configured any point of time.
Please let me know if is there any spe
Yea the docs weren't really clear about it, so I just thought it would work
for anything that implemented Comparable =)
Yep, used the long from getTime() - not the prettiest way of doing it, but
it works great.
Thanks!

Hi,
I have setup about 10 rules in the rulebase. Can you tell me how I
can execute more than one specific rule at the same time? Please help
Thanks

yes I think that it's perfectly possible..
As long as you load first the drl file that include the definitions and then
the processes that uses that data types.. it should work.
Let us know if you find any problem around that..

Hello, we are starting a project using Drools and we are interested in the
conbination of fact models defined in drl files and processes.
We have been looking for documentation regarding this issue, but we have
seen only examples of combining drl-defined types from within rules.
We are interested
Hey All
Can anyone please point me to documentation explaining how to get a WSDL
with a service endpoint generated for the Drools server?
Cheers!

As Greg eludes to the default "min" accumulate function expects
(java.lang.)Numbers.
If you require one to handle dates you can write your own custom Accumulate
Function.

That's because a java.util.Date is not a java.lang.Number. :) You can get the
long value behind the Date by calling Date.getTime(), though. Try that.

Hi,
We almost reach to merge 2 repositories using eclipse plugin but had to
create first package then upload the new model jar then only the
ressources. Still have tests to do to be sure it's doing all well.
But now i face problem with package generated with Guvnor.
I generate a full package wit
Should I be able to do an accumulate min over java.util.Date objects? Like
this:
$minDate : Date() from accumulate(MyFact ($startDate : startDate),
min($startDate))
I would have thought so, but when I try it, I'm getting:

Any chance that this could be reviewed and maybe integrated into the

Hi
General question on the drools planner. If I'm not mistaken, I see three
ways to impose hard constraints:
1. Generate violations in the scoring DRL.
2. Check them in isMoveDoable
3. Do not create moves in the MoveFactory which cause hard constraints to be
broken.
For safety I would always a

My rule that I'm using in unit testing only looks like this:
rule "Testing contains"
dialect "mvel"
when
Response( $answerSelections : answerSelections )
AnswerSelection( answer.ID in (2, 3) )
then
System.out.println("Testing contains activated")
end
Response has a getAnswerSele
Hi, I don't know where that code is but it's very easy to create your own
work item. You can create your own using any type of framework and
communicate with any other type of application.

Maybe your actual business needs have a procedural, flow chart like

If your needs are mostly declarative and you'd like to handle a rare

If you don't want to change your rules (add conditions, controls facts
...), you can set an AgendaFilter that only accepts rules not executed yet.
If your rules are not chaining (ie one rule changes an attribute that
trigger another rule), you should use sequential mode.

I tried lock-on-active and it is better than no-loop because it can avoid
activate other rules in a group. Maybe it is too strong for me.
What I want is :
rule 1 change a attribute and it tells other rules (for example, rule 2)
that the fact data is changed. rule 2 change another attribute, but d
Your best starting point would be to read the Drools Expert documentation
and look through the examples.
Any questions you may subsequently have can be asked here and people will
always be willing to provide assistance.
With kind regards,
