Re: [rules-users] Guvnor errors stay forever
Please raise a new JIRA for the first problem (HTTP500). Please include an example rule that causes the failure. The second issue, I believe, is the same as https://issues.jboss.org/browse/GUVNOR-1465.

An old error will always come again even though the item it refers to is not even existing anymore (so I cannot analyse/verify anything reliably). I renamed the above function, I edited it so it doesn't have the chevrons, its code can be validated fine, but nevertheless Guvnor keeps throwing the same error 500 and the JBoss console keeps complaining about the ld function calculateAge and its chevrons each time I verify or analyse. And it does that by repeating the message for each retry once more. Either the error list is not cleaned after the verify, or some artifacts live too long.

[rules-users] Using Enumeration for long lists
Hi, We are planning to use Drools for a Blacklist validation logic which requires us to manage very long list (could be tens of thousands of IDs). Can we use the native Drools enumeration for this? Would this be an optimal implementation? The other option we were thinking of was to have a list managed separately in our core application and have in lucene indexed such that Drools rule checks against the index. But, as you can see, it creates a lot of development as well as maintenance overhead. Thanks in advance for any tips on this topic.

Re: [rules-users] Using Enumeration for long lists
How complex are the blacklist rules that you are planning to have? From what you have described it sounds like it is just substring/startswith matches? If this is the case then you may be better just to query lucene or the database directly as you'll result in a very flat extremely wide graph that drools isn't going to be able to optimize at all - it will basically just iterate over every string doing the string comparison. Lucene/the database are likely to be much more optimized and efficient for this. If on the other hand your blacklist logic is much more complicated, taking into account multiple criteria such as username, time of day, source ip address, phase of the moon etc then drools may be easier to optimize development speed and maintainance,.

Re: [rules-users] Using Enumeration for long lists
Guvnor supports enumerated lists of values that can be included in rules. Drools itself (the rule engine) provides for the compilation and execution of rules; ultimately written in plain text - Guvnor provides a UI layer of abstraction over the text generation that allows use of enumerations. You can use Java enumerations in Drools rule definitions, but you still need to write the rules using such enumerations.

Re: [rules-users] Retrieving Enumerated List from Drools
Hi, Sorry for the minimal information. We have a B2C application which is basically into eCommerce. You can consider it another amazon or ebay. And one thing we do today in a very crude way is personalize the appearance and content (ie., products, pricing of products, banner images, etc) based on the user profile. For example, on Valentine's day if the user is a male, he gets to see gifts for a female and vice versa. So, as part of a Solution revamp, we have decided to use Drools to manage product visibility by having a rule which says... if the user is male, dont show this but show that as a basic example. Now, there are certain functionalities we have as core in our Content Management System (like a custom Joomla or Drupal) which we wouldnt want to migrate entirely to Drools. So, we would define the segments in Drools and map such segments to the existing entities. eg: Segment can be Male vs Female with Segment Codes SEG_MALE and SEG_FEMALE as an example where SEG_MALE and SEG_FEMALE are two possible values in an enumerated list. Now, this being the situation, we want to be able to retrieve this list of enumerated values into our CMS so that we can map them to existing entities like banner images. Hope this helps.

Re: [rules-users] Retrieving Enumerated List from Drools
OK, I'd see your use as something like this:- 1. Define the rules (you give an example of) 2. At runtime insert appropriate facts into a KnowledgeSession 3. The rules return some indicator of the appropriate customisation required If this makes sense, you should probably read about using Globals (to return a list of customisations out of WM) or StatelessSessions (which sounds more appropriate, for scalability).

But in this case, I'll have different facts in both sessions, and it's possible that my rules don't fire. Has drools implemented clustering for statefull sessions? or how should I do, because if both session are containing the same facts, the rules will be triggered twice...

[rules-users] Absence Pattern question
Hi, I'm having trouble writing an absence pattern. What I'm trying to do is detect when there is an A followed by no Bs for 3+minutes. I don't care if there is more than one A. What I'm running into is that when I try to use 'over window:time' the time within drools is the end time of the window. So this means I need to write the no Bs for 3+ min first: not( $b: B() over window:time(3m)) then try to find the A before it: $now: Long() from RuleUtilityFunctions.getSessionClockTime() $a: A( this before [3m] $now) then I should have to check to make sure that I don't have any Bs between $a's time and the start of the no B window: not( B( time = $a.time, time = $now)) This is not working. I think that it has something to do with my function to get the session clock time (RuleUtilityFunctions.getSessionClockTime()) and how things get evaluated within the Rete engine. Because it does not seem like $now is getting re-evaluated on future calls that pass the $b condition. If I replace $now with the call to getSessionClockTime() everything just seems to get weird. I've tried to write the rule forward too. Look for A followed by no B but that does not seem to work because A is matched at the current time and the rule triggers because there is no B because the future B data has not be inserted into working memory yet. What is the right way to write this rule? Is there a way to get the start and end time of the time window that met the over window:time() condition?

Hi,

'over window:time' the time within drools is the end time of the window.
So
this means I need to write the no Bs for 3+ min first:
not( $b: B() over window:time(3m))
then try to find the A before it:
$now: Long() from RuleUtilityFunctions.getSessionClockTime()
$a: A( this before [3m] $now)
then I should have to check to make sure that I don't have any Bs between
$a's time and the start of the no B window:
not( B( time = $a.time,
time = $now))
This is not working. I think that it has something to do with my function
to get the session clock time (RuleUtilityFunctions.getSessionClockTime())
and how things get evaluated within the Rete engine. Because it does not
seem like $now is getting re-evaluated on future calls that pass the $b
condition. If I replace $now with the call to getSessionClockTime()
everything just seems to get weird.
I've tried to write the rule forward too. Look for A followed by no B but
that does not seem to work because A is matched at the current time and the
rule triggers because there is no B because the future B data has not be
inserted into working memory yet.
What is the right way to write this rule? Is there a way to get the start
and end time of the time window that met the over window:time() condition?
Thank you,
Wendy

Re: [rules-users] Absence Pattern question
Won't that just make the rule activate after 3 minutes?
rule AnoB
when
$a: A( status == waiting for B )
not B( this after [3m] $a )
then
modify( $a ){ setStatus( no B within 3m after me ) }
end
Is this any good?
Also untested ;)

Try a rule with a timer:
rule AnoB
timer( int: 3m )
when
$a: A( status == waiting for B )
not B( this after $a )
then
modify( $a ){ setStatus( no B within 3m after me ) }
end
Untested.

[rules-users] Can we use a Collection in LHS maintained in Guvnor
Hi All, Is there a way in which we can use a collection in LHS of a rule (to be used in contains, memberof) , which can be managed in Guvnor containing big list of elements (may be 10,000). Having this in a Database is an option but considering the maintenance of the list where in a user(who doesn't have Database Knowledge) has to update the list frequently, can this collection be maintained in Guvnor and used in LHS of a rule.

Cuscar is defined in my model and it contains an ArrayList called UNB (with

let me select the correct options for the type ArrayList from the drop down

the identifier that doesnt seems to recognize is size(), I have already
tryed this rule:

end
and it compiles just fine... I wonder if it has something to do with the

I am running Gunvor 5.1, and try to deploy this build in SAP NetWeaver 7.3 The
SAP server is using JDK6. The error I get when deploying is this: Caused by:
com.sap.engine.library.bytecode.cf.CFException: Invalid constant pool tag, 60
at index 41.
I checked SAP user forum, and I found one old post re migrating some J2EE
applications from JBoss 4.2.3 but there was no fix for that.
I know that this looks like a NetWeaver issue, but I wonder if anybody else
tried to deploy Guvnor in SAP server, or has any NetWeaver deployment
experience that can share. Also, if anybody ran into this issue (Invalid
constant pool tag, 60 at index 41.) can tell how did they fix it? It might help
in my case.
I would appreciate if someone has any input here.
Thanks,

Re: [rules-users] get inserted facts
Without knowing your use cases, or what you intended to do with the facts once you retrieve them, I'd suggest that you could simply add them to a global list and examine the list contents after rule processing. For example: import java.util.List; global List results; rule IWantToTrackMyConsequenceFacts when Type1(filter1 =1) then Fact someFact = new Fact(); insert(someFact); results.add(someFact); end Prior to executing the rule(s) you will have to set that global variable to a valid list object with something like this: knowledgeSession.setGlobal(results, new ArrayList()); From: rules-users-boun...@lists.jboss.org [mailto:rules-users-boun...@lists.jboss.org] On Behalf Of Ruault Gaetan Sent: Tuesday, July 05, 2011 5:13 PM To: Rules Users List Subject: [rules-users] get inserted facts Hi, I use drools in stateless Session like this : session.execute( my_facts_list) ; and i have many rules like this when Type1(filter1 =1) Then Insert( new Fact()) ; Could you explain how it's possible to retrieve my new facts in java code ?
