[rules-users] Call of a function in the definition of a rule template
Hi every one, I defined a function in Guvnor and I want to call it to define a rule template. But I do not know how. Have you any ideas? Thank you in advance ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] How to get the Fact datatypes from the Guvnor

Hi All,
Can anybody help to get the Field type(what datatype it is ).
I have declared a Facts in Guvnor 5.3 and i can able to retreive all the
package names rules names fact names , now i want to know what is the
datatype of each fact , i don't know which api to use for this.
Can any body help me pelase...
below code to get the all package names rules names fact names...:
CollectionKnowledgePackage kpackages =
_kagent.getKnowledgeBase().getKnowledgePackages();
for(KnowledgePackage kpackage : kpackages)
{
for(org.drools.definition.rule.Rule rule1 :kpackage.getRules())
{
//printing package names rule names.
String packname= rule1.getPackageName();
String rulename=rule1.getName();
System.out.println(This is : +packname+ Packages and
RuleName is +rulename);
//printing Fact names..
Field[] s=kpackage.getClass().getFields();
Method getClass() is inherited from java.lang.Object and returns the
object's java.lang.Class. Therefore, the Field[] s are the fields of
java.lang.Class().
There is no (stable) way of retrieving the declared fact names from a
KnowledgePackage.
If you are willing to use the *UNSTABLE* API, look at all (!) of
http://drools.46999.n3.nabble.com/Fact-Names-in-a-Model-td3572234.html
-W
System.out.println(s.toString());
}
}
Thanks,
Veera

Re: [rules-users] Call of a function in the definition of a rule template
It is not so easy to create rules programmatically (if that's what you mean). You could use the experimental (unstable) fluent API (see 2.2.2.6. Rule API in the Drools Introduction and General User Guide), but this is a rather inconvenient way of accumulating strings to create a package. I'd rather create a String and feed the DRL compiler with it, but YMMV. -W 2012/2/13 freelance developpement developpement.freela...@gmail.com Hi every one, I defined a function in Guvnor and I want to call it to define a rule template.

If your browser's locale is fr_FR and you are using the Guvnor WAR from herehttp://www.jboss.org/drools/downloadsyou should already see the French version. If your browser locale is not fr_FR you can still access the French UI by appending ?locale=fr_FR to your URL.

As Michael said, Guvnor already has French support.

[rules-users] (no subject)
According to the documentation:
Rule constraints do not have direct access to variables defined inside the
process.
It is however possible to refer to the current process instance inside a
rule constraint,
by adding the process instance to the Working Memory and matching for the
process instance in your rule constraint.
We have added special logic to make sure that a variable processInstance
of type WorkflowProcessInstance
will only match to the current process instance and not to other process
instances in the Working Memory.
Note that you are however responsible yourself to insert the process
instance into the session and,
possibly, to update it, for example, using Java code or an on-entry or
on-exit or explicit action in your process.
The following example of a rule constraint will search for a person with
the same name as the value stored in the variable name of the process:
This however does not seem to be true.
The first rule is to receive a stream of objects of type MyObject.
This rule starts an associated process.
The second rule will be called by the process (from bpmn).
Within the process there a task that invokes an an asynchronous service, ie,
an implementation of WorkItemHandler that contains a Thread that will set
call
manager.completeWorkItem(workItemId,results);
when 30s have passed).
With this setup we can observe what happens when 2 MyObject instances come
into the first rule separated by a short period of time (say 5 seconds).
When the first object comes in a process is created and started (with
process id=1)
The process passes from the start node to the callMyTask node, which
invokes the slow WorkItemHandler references by MyTask
(which we have previously registered into session.getWorkItemManager() ).
Because the WorkItemHandler has a thread that waits 30s before completing
the work item, it just sits there doing nothing (so far everything is ok)
and allows the engine to process other events.
5 seconds later we insert another MyObject into the stream.
The first rule gets fired and created another process (with process id=2).
The process passes from the start node to the callMyTask node, which invoke
our slow service.
We have thus two processes running in parallel.
When the first callMyTask node completes, the next node completeTask is
invoked.
The rule process complete is matched as it belongs to the rule flow group
Complete task group.
At this point we observe that the rule is matched twice spitting out:
processInstance.id 2
processInstance.id 1
.
So the rule has matched both process instances that are in working memory
and not just the one (with process id 1)
that called the process complete rule.

Re: [rules-users] (no subject)
I had some tests working fine in jbpm 5.1 but failing in 5.3 because of
this same reason. I'm not sure if this is this is a regression bug or if
there is a deliberated change in the behavior.
Maybe someone in the jbpm dev team can shed some light here.

Re: [rules-users] (no subject)
We're using 5.2.0 final here.
What we are also observing is that whenever a process instance reaches a
businessruletask node the rule gets fired a number of times equal to the
number of instantiated processes even if any of those processes didn't
reach the bussinessruletask node.
Does this means that whenever a businessruletask is reached in any of the
current process instance, the rule gets fired for *all* the instances of
the process and subsequent businessruletask nodes won't fire anything?

Re: [rules-users] (no subject)
The behavior you described is how it is working in 5.3 (and it seems 5.2 too). The rule is fired once per process instance you have in your working memory no matter if the others instances are, are not yet or even has already been in that Rule Task Node. Again, I'm not sure if this is a deliberated feature or a bug, but according to the documentation, it is a bug. One workaround could be that the process inserts a control fact containing its own id right before the Task Node is ejecuted (this could be done in a listener or in the on-entry action property of the node). Your rule then will look like this: rule process complete ruleflow-group Complete task group when $ControlFact($id: processIntanceId) $processInstance: WorkflowProcessInstance(instanceId == $id) then System.out.println(processInstance.id + $processInstance.getId()); retract ($id) end Best Regards, Esteban Aliverti - Developer @ http://www.plugtree.com - Blog @ http://ilesteban.wordpress.com 2012/2/13 Alberto R.

Re: [rules-users] Performance scaling with fact insertion
There's several things to be noted with the way you've set up these tests.
(1) You run all tests (Logical, Manual, Modify) with all three rules being
in the KnowledgeBase. This means that all insertions result in the creation
of activations for all three rules while firings are restricted using the
agenda filter.
(2) I suppose that you ran the tests, one after the other, as one usually
does using Eclipse/JUnit. It's cleaner to do one test in a single run,
preferably not inside Eclipse.
(3) You should be able to control -Xms and -Xmx from the command line, to
see how heap size increments affect execution times.

The time it takes to run is n-squared in the number of posts. For 4000, 8000,
16000, 32000, 64000 posts the time is (in 1/10 seconds):

Re: [rules-users] Performance of collect seems to be n-squared
Just FYI, the array list is created once and reused with incremental
addition/removal of elements.
The problem is that the engine does not know when you are done inserting
all the Post facts, so each post inserted is propagated down the network
with the cancellation and reactivation of the rule.
This is one of those situations where a use of a control fact might be
recommended, if you are inserting Post facts in batches. E.g.:
rule X
when
exists( AllPostsInserted() )
$a : ArrayList(size 0) from collect(Post());
then

Re: [rules-users] Fwd: Migrating repository data from Drools 5.0 to 5.3Final
This is fine. 5.2 onwards groups columns for the same pattern together - if you looked at the DRL fo 5.0 you'd have seen the columns are effectively grouped together too. For example; given the following 5.0 configuration (taken from what you describe you have done):- Pattern $a : Column A - Condition 1 Pattern $b : Column B - Condition 1 Pattern $c : Column C - Condition 1 Pattern $d : Column D - Condition 1 Pattern $a : Column E - Condition 2 Pattern $b : Column F - Condition 2 5.0 DRL $a : Pattern( Condition 1, Condition 2 ) $b : Pattern( Condition 1, Condition 2 ) $c : Pattern( Condition 1 ) $d : Pattern( Condition 1 ) Importing this into 5.3 groups the columns:- Pattern $a : Column A - Condition 1 Pattern $a : Column B - Condition 2 Pattern $b : Column C - Condition 1 Pattern $b : Column D - Condition 2 Pattern $c : Column E - Condition 1 Pattern $d : Column F - Condition 1 5.2 DRL $a : Pattern( Condition 1, Condition 2 ) $b : Pattern( Condition 1, Condition 2 ) $c : Pattern( Condition 1 ) $d : Pattern( Condition 1 ) Furthermore, at the request of the community, the behavior of default values changed so that the are only the default value for a new row (5.2 onwards) and not the value used for an empty cell (5.0). I know this has caused some re-work for people migrating a legacy decision table from 5.0 to 5.2 but since the impact, to date, has been small I do not plan on making any programmatic changes. With kind regards, Mike 2012/2/13 jian zhi jianp...@yahoo.com Mike, Thanks for the detail explanation. I found that the order of the conditions were changed again after I added two more conditions to the same package I used last time. I added default value to the first two conditions. Added the fifth condition by using the binding name created for the first condition.Add the sixth condition by using the binding name created for the second condition. After I import the data to 5.3 the fifth condition became the second and the sixth condition became the fourth. Also the default value for the first and second conditions are not listed in the rule source in 5.3. Could you please take a look? I attach the modified repository in the email.

[rules-users] MVEL strict-mode vs. performance
Hi, We are upgrading from Drools 5.1 to 5.3 to improve the performance, but we are hoping to keep our drl files intact. We were trying to use the old drl files by setting drools.dialect.mvel.strict=false, but somehow with this setting we still got unable to resolve method using strict-mode .. error from time to time. I'm wondering if there is any correlation between this strict-mode and the performance gain, if in order to achieve the performance gain, we have to set the strict-mode to true, then we will make changes to our drl files, instead of spending time to figure out why the effect of drools.dialect.mvel.strict=false is sporadic.

Re: [rules-users] rules-users Digest, Vol 63, Issue 60
I don't understand either of these answers. All of the facts are in a list of
facts passed into ksession.execute, like this:
final StatelessKnowledgeSession ksession =
kbase.newStatelessKnowledgeSession();
ListObject facts = createPosts();
if (facts.size() == 0) break;
long t0 = System.currentTimeMillis()/100;
ksession.execute(facts);
long t1 = System.currentTimeMillis()/100;
System.out.println(Elapsed time: + (t1 - t0));
There are no more facts getting created during rules processing. The whole drl
file is:
rule collect
when
$a : ArrayList(size 0) from collect(Post());
then
System.out.println(Number of posts: + $a.size());
System.out.println(DONE);
end
Why is the collect happening more than once? Actually I don't think it is, else
I would be seeing more than one printout.
I agree that I could probably find a way to do without the list, but I would
still like to understand why this is n-squared. I was actually planning to
explore the performance of various ways to compute the minimum of a large
number of objects. I was surprised to find that I was already up to n-squared
just creating the list.

[rules-users] Using Character typed properties in Drool 5.3
Community,
In drools 5.2 I had the following LHS
when
BloombergColumn (columnName == CRNCY, $cur : stringValue != null)
Country (currency == $cur, emergingMkt == 'Y' || countryCode in
(BH,HR,CZ,EE,HK,HU,IL,KR,KW,MO,OM,QA,SA,SG,SK,SI,TT))
I am switching to Drool 5.3, and Drools Guvnor reports the following error upon
validate (or compile):
[bum_code_value.currency 01] Unable to Analyse Expression emergingMkt
== 'Y' || countryCode == BH || countryCode == HR || countryCode == CZ ||
countryCode == EE || countryCode == HK || countryCode == HU ||
countryCode == IL || countryCode == KR || countryCode == KW ||
countryCode == MO || countryCode == OM || countryCode == QA ||
countryCode == SA || countryCode == SG || countryCode == SK ||
countryCode == SI || countryCode == TT: [Error: Comparison operation
requires compatible types. Found class java.lang.Character and class
java.lang.String] [Near : {... == SK || countryCode == SI || countryCode ==
TT }] ^ [Line: 7, Column: 28]
Looking at the emergingMkt in my data model, I see that it is defined as a
Character. If I change my LHS to:
BloombergColumn (columnName == CRNCY, $cur : stringValue != null)
Country (currency == $cur, emergingMkt == Character.valueOf('Y') ||
countryCode in
(BH,HR,CZ,EE,HK,HU,IL,KR,KW,MO,OM,QA,SA,SG,SK,SI,TT))
Then the validate passes.
Was this change in behavior intentional? I don't see a reference to this
change in the Drools 5.3 documentation, and this makes for a harder to read
rule for our Drools analysts.
Thanks in advance,
Armand

Re: [rules-users] Using Character typed properties in Drool 5.3
Correction:
Even using Character.valueOf('Y') does not work anymore in Drools 5.3. The
validate works, but the compile steps fails because Drools is treating 'Y' as a
String. However, in Drools 5.2 and prior, 'Y' was properly casted to a
Character when the property it was being compared to was a property of type
Character.
If anyone has any insight on where the documentation address this change in
behavior, I would appreciate some guidance. I am trying to re-standardize how
our rules are coded for evaluating Character typed properties.

Subject: [rules-users] Using Character typed properties in Drool 5.3
Community,
In drools 5.2 I had the following LHS
when
BloombergColumn (columnName == CRNCY, $cur : stringValue != null)
Country (currency == $cur, emergingMkt == 'Y' || countryCode in
(BH,HR,CZ,EE,HK,HU,IL,KR,KW,MO,OM,QA,SA,SG,SK,SI,TT))
I am switching to Drool 5.3, and Drools Guvnor reports the following error
upon validate (or compile):
[bum_code_value.currency 01] Unable to Analyse Expression
emergingMkt == 'Y' || countryCode == BH || countryCode == HR ||
countryCode == CZ || countryCode == EE || countryCode == HK ||
countryCode == HU || countryCode == IL || countryCode == KR ||
countryCode == KW || countryCode == MO || countryCode == OM ||
countryCode == QA || countryCode == SA || countryCode == SG ||
countryCode == SK || countryCode == SI || countryCode == TT: [Error:
Comparison operation requires compatible types. Found class
java.lang.Character and class java.lang.String] [Near : {... == SK ||
countryCode == SI || countryCode == TT }] ^ [Line: 7, Column: 28]
Looking at the emergingMkt in my data model, I see that it is defined as a
Character. If I change my LHS to:
BloombergColumn (columnName == CRNCY, $cur : stringValue != null)
Country (currency == $cur, emergingMkt == Character.valueOf('Y') ||
countryCode in
(BH,HR,CZ,EE,HK,HU,IL,KR,KW,MO,OM,QA,SA,SG,SK,SI,TT))
Then the validate passes.
Was this change in behavior intentional? I don't see a reference to this
change in the Drools 5.3 documentation, and this makes for a harder to read
rule for our Drools analysts.
Thanks in advance,
Armand

Re: [rules-users] rules-users Digest, Vol 63, Issue 60
It would almost seem as though the collection is a sort of sub rule that fires
for every insert, and generates temporary fact collections based on the
results, and so, even though you are inserting all the facts before calling the
execute in the stateless session, each and every single fact is being evaluated
for the collect sub-rule to build the new collections, and then those new
collections are fed into the actual rule as temporary facts unique to that
rule. And that perhaps this is the source of the n-squared processes.
Have you tried a more literal approach like this? (based on your comment that
you are looking for the minimum)
(assuming there is a property called Value that you are looking to get the
minimum of)
rule minimum
when
Post($v: value)
not Post(value = $v)
then
System.out.println(Minimum value: + $v);
end
rule maximum
when
Post($v: value)
not Post(value = $v)
then
System.out.println(Maximum value: + $v);
end
Of course, this has not direct ration to what you are trying to do, but rather,
I am focusing on your comment that you trying to focus on computing the minimum
of a large collection of objects.
I wonder if accumulate might do a better job in solving your original problem,
since accumulate could allow you to calculate min, max, average, count, sum,
return collections as List and Set of data..
Take a look at section 5.8.3.6.4.1 of the Drools Expert manual for details on
use, and 5.8.3.6.4.2 for details on creating your own functions which could do
all of these in one, which would greatly reduce the number of iterations
through your source collection.

I don't understand either of these answers. All of the facts are in a list of
facts passed into ksession.execute, like this:
final StatelessKnowledgeSession ksession =
kbase.newStatelessKnowledgeSession();
ListObject facts = createPosts();
if (facts.size() == 0) break;
long t0 = System.currentTimeMillis()/100;
ksession.execute(facts);
long t1 = System.currentTimeMillis()/100;
System.out.println(Elapsed time: + (t1 - t0));
There are no more facts getting created during rules processing. The whole drl
file is:
rule collect
when
$a : ArrayList(size 0) from collect(Post());
then
System.out.println(Number of posts: + $a.size());
System.out.println(DONE);
end
Why is the collect happening more than once? Actually I don't think it is, else
I would be seeing more than one printout.
I agree that I could probably find a way to do without the list, but I would
still like to understand why this is n-squared. I was actually planning to
explore the performance of various ways to compute the minimum of a large
number of objects. I was surprised to find that I was already up to n-squared
just creating the list.

Repeatedly creating this ArrayList is bound to be O(n2).
Why do you want the Post facts as a List? There may be better ways for
achieving your goal.

Re: [rules-users] Multiple threading
Sorry to burst your bubble, but stateful knowledge sessions are most definitely not thread-safe. I have seen hard evidence to this effect in the form of incorrect execution results and log statements that clearly show that two threads were interacting in unexpected ways. In a nutshell: Rule consequences are not executed atomically. This can cause unexpected working memory changes (e.g., fact insertion) to happen on one thread in one rule consequence before another thread has finished executing another rule consequence. Note that I'm not talking about whatever threads Drools may be creating internally. I'm talking about application threads. I have found synchronizing on the session object to be a reliable safeguard against unwanted thread interactions. Basically, this way all external fact insertions and calls to fireAllRules() are serialized. If this is not supposed to be necessary (synchronizing on the session), then there is a thread-safety bug in Drools. -Richard 2012/2/10 Mark Proctor mproc...@codehaus.org On 10/02/2012 03:36, Apache wrote: Hey, I am trying to get multiple threads to insert events and run rules against the union of events inserted ( an as soon as they are inserted, a timer drools thread kicking of fireallrules() is not an option because that would introduce a delay ) and wanted some opinion on the following: 1.

Re: [rules-users] MVEL strict-mode vs. performance
Have a read of the release notes around type safety. There are some situations where Drools was not correctly enforcing type safety, which have since been corrected. So probably a badly written rule is now getting picked up. As a work around you can force some patterns to evaluate dynamically using @typesafe.
