User defined structure of facts
by Rudolf Kadlec
Is it possible to define slots which wouldn't be obtained by Java
introspection? We want to apply Drools rules to object written in
Python (Python will be connected to Java through Java Scripting API).
We already have our own introspector for Python and now we need to
define arbitrary structured facts in working memory.
Any hints?
Thanks

Keyword to Stop firing rules
by Rajesh.Sachin10
There is any keyword available to stop the rules firing after some condition?
EG:
[when] \\condition 1
[then] \\ do something
[when] \\condition 2
[then] \\ do something and stop the rules from firing.
My 2 rules are in loop structure. Both the rules will fired still the
condition 2 satisfies. Once the condition 2 satisfy, it should not fire the
first rule again. It should come out from the dsl itself.

Drools 4 with Spring
by Miguel Figueiredo
Hello listers,
I am testing the integration of Drools 4 with Spring and I want to use the
following:
1. Load rules from a database
My approach was to store rules in a table with the columns: name, conditions,
actions. Then build a string with the various rules and load it with a
package builder from the String's InputStream.
Is there a better way to do this?
2. Use Spring beans in the rules
I want to use spring beans and DAOs in the rules. Can I do this? How?
I hope that someone can help me.
Best regards,
Miguel

Need help in finding which clause[Expression] in the rule failed
by Ashwini Joshi
Hi,
I have also sent this problem before. But did not get any reply. It is
urgent. Does anyone know about this?
Suppose I have a rule as
rule "Rule1"
when
Message( message == "Hello" ) || Message( status == 0 )
then
System.out.println("then executed");
End
Is there a way to find out which condition is satisfied? I.e. whether
message was equal to "Hello" or status was 0.
We are generating alerts using rules engine, and in the alert we need to
specify that which clause generated the alert.
We are having multiple clauses in a single rule. So what is the correct way
to find the clause because of which alert is generated. We cannot keep them
in separate rule because we need to consider and\or conditions between these
clauses.
Thanks,
Ashwini

RE: [rules-users] Need Help On Modify
by Sikkandar Nawabjan
Hi,
This is pretty much expected behaviour. If you modify the facts in working memory and if the changes satisfy the rule obviously it will fire. So you can do one thing. u can modify the corresponding DTO such a way that it is not satisfying the predicate logic in the previous 5 rules.
If the current object is firing again and again u can use the attribute no-loop truue
Any other better options from anybody?
Thanks and Regs,
basha

Hi,
I am having set of rules; each DTO (Java Bean with getter
and setter) will go under these rules.
Lets take I am having 10 rules the DTO has to change its
value at 5th rule.
So I am changing the value in DTO and calling modify(DTO),
so what's happening is again this changed DTO is executing form RULE1
I want this DTO to execute from Rule 6 or Exit from all
Rules
Please help me it's urgent
Regards

Persistence & Clustering
by jean safar
Hi,
I have started to look at drools and I had the following questions.
Apologies if that is in the doc or in the archives of the mail group, but I
did not find any answer.
1) Is there some support (is it a valid question?) for the persistence of
the working memory and state of the engine? Or is it easier to just reassert
all objects ?
2) Is there any support to grid/cluster the engine? Can the working memory
use a distributed cache ?
Best Regards,

RE: [rules-users] name
by Michael Rhoden
Wonderful idea. D-rules or some variant is much better than the previous
2 names :)
Telling an exec we saved a lot of time & money using this system called
"Drools" always got me a few looks. Likewise I dont go around saying
the new version of JBoss Hibernate is out.
