[rules-users] Drools Rules : Getting Started Tutorial Link Required
Hi, I am new to Drools Rules and using Drools-5.5.0.Final in my project. I need to know , how to setup JBPM runtime engine to perform rule evaluation for BusinessRule Nodes. Is there any separate server required for it or can it be done with in JBPM runtime. I need a tutorial on setup/configurations and a tutorial on rule writing, model uploading. I need to know that how to pass fact dynamically at runtime when a Business Rule Node is reached. Thanks and Best Regards, Zahid Ahmed Senior Software Engineer ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] multiple expiration definitions for the same face type in different drl files
Hi all, I am examining Drools Fusion in stream mode. This is my case: I have several drl files. Each drl file contains one rule. Each drl file is built to a knowledge package. Each drl file contains declaration of the same fact (referencing to a imported class defined outside of the drl). The fact's role is of course event. Can I define different expiration (@expires) for the fact in each drl? Is expiration relevant only to the same drl? Is the answer different if the fact is created in the rule's RHS or if it inserted to the session's working memory outside of the drl? Thanks. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

[rules-users] Help on writing a rule
Hi Guys. I have one quesiton on how could I implement my rule. I have this rule: when t : PriceChange() over window:length(1) signal : Signal( id == 1234 ) over window:length(1) not OrderCreated( id == 1234 ) over window:time (1m) then insert(new OrderCreated(1234)); Basically, when there is some signal and some price change, create a new order if there has no been any other order in the last minute. But this sometimes is being fired twice: 12:31:01,121 INFO [org.drools.audit.WorkingMemoryConsoleLogger] (Camel (camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED rule:ertetr activationId:ertetr [393, 392, 0] declarations: t=PriceChange [](392); signal=Signal@1413ddef(393) 12:31:01,160 INFO [org.drools.audit.WorkingMemoryConsoleLogger] (Camel (camel-1) thread #4 - JmsConsumer[marketDataTopic]) ACTIVATION CREATED rule:ertetr activationId:ertetr [393, 394, 0] declarations: t=PriceChange [](394); signal=Signal@1413ddef(393) I think that, when the 1m window have passed, it creates twice the activations, as I have not called fire all rules yet. Does is make sense? Do you have some idea on how could I implement this rule? when there has been some price change and some signal, and I did not create a new order in the last minute, just create a new order.

Re: [rules-users] Help on writing a rule
Am I wrong or do you have two PriceChange events - 392 and 394 ? If so, you can expect two activations.. when you fire al rules, one of the two will insert the OrderCreated, which in turn will cancel the other On 10/22/2013 01:34 PM, calcacuervo wrote: Hi Guys.

Re: [rules-users] Help on writing a rule
Yes! I receive many price change events.. but, as I am using window length = 1, I would expect to have the activation cancelled for the previous one? I am not sure how to express this: when there is some price change, and some signal, and there has not been any order over the last minute, then place an order The price change and signal are like existence facts.. If there is some price change change.. if there is some signal ... Would this be another way to achieve what I am trying to do? Thanks, Demian PS: This is a simple rule, but then, the idea is to have more complex rules.. like, if there has been 10 signals in the last time, place an order, etc. On Tue, Oct 22, 2013 at 5:40 PM, Davide Sottara dso...@gmail.com wrote: Am I wrong or do you have two PriceChange events - 392 and 394 ?

Re: [rules-users] Help on writing a rule
Mauricio, In fact, I used to have this and the price change without window:length.. but when t : PriceChange() signal : Signal( id == 1234 ) not OrderCreated( id == 1234 ) over window:time (1m) But this will cause more and more duplicates orders (and it have sense!). I added the length window to 1, as I would only like to create an order if there is some signal in the window, it can place an order..

[rules-users] Why no rule will be fired if class name and attribute name is same
Why no rule will be fired if class name and attribute name is same?
Following is my drl file content:
package test
declare input
input : String
end
declare output
taskname : String
end
rule Rule A
dialect mvel
salience 0
no-loop
when
$input:input(input == a)
$output:output()
then
modify ($output) {taskname = Hello};
end
But if I created a fact object of input and set attribute input to a, it
did not fire any rules.
