execute once for an accumulate
by dwipin
I have the following condition and consequence in one of my rules -
when
$position : PositionValuation() // returns 4 records
eval(helper.isSameDay($position.cobDate, $request.cobDate)) // filters 1,
so count =3
$pnl : PnL() from $position.pnl
$totalPnlValue : BigDecimal()
from accumulate(PnLTimeValue(type == "TOTAL", $pnlAmount : grc.value)
from $pnl.dtdAmount ,sum($pnlAmount))
then
logger.debug("variance :"+$totalPnlValue);
exception.setOrganisation($position.organisation);
exception.setCobDate($position.cobDate);
exception.setOrganisation($position.organisation);
exception.setTrade($position.trade);
$outputList.add(exception);
I want to have have the rule executed once for the accumulated value. How do
I achieve this?
Currently this gets executed 3 times.
Thanks,
Dwipin.

Error opening process in Oryx editor (designer-1.0.0.052)
by Grzegorz Błaszczyk
Hi,
I started with a fresh JBoss installation:
* jbpm-5.0.0-installer-full.zip
** designer-1.0.0.052
** jboss-5.1.0.GA
** drools-guvnor 5.2.0.M1
** drools-5.2.0.M1
** eclipse-helios
There was a tiny problem with h2 artifact - it should be downloaded
from a different location (dedicated Nexus in JBoss.org network).
Things done after the installation:
1. samples in Guvnor installed
2. DRL and BPMN files of our process file and subprocesses from a
dedicated eclipse to Guvnor uploaded
3. package classes filtered out and package validated
4. package compiled
Up to now this went smootly.
After that when I open a process editor (Oryx) in Guvnor I get:
java.lang.IllegalArgumentException: No profile with the name drools
was registered
org.oryxeditor.server.EditorHandler.doGet(EditorHandler.java:286)

In JBoss console I get the same:

I added a role in Guvnor named 'drools' with admin privileges but it
didn't solve the problem.
What should I configure to have a 'drools' profile and be able to open
the process in Oryx editor ?

Using multiple Collect() From result in null pointer exception
by Hezi Stern
I have encountered the following issue when running a rule that has more
than 1 collect from a same collection.
I have the following two rules:
rule "filter sentences based on existence of attributes"
when
IPhoneQueryCmd(State.POPULATE == state,
$tidt: targetId)
$attributeFilteredSentences: ArrayList()
from collect (IPhoneSentences.Sentence(
( (descriptor.targetPrivatename == false) || (descriptor.targetPrivatename
== $cmt.sentenceFilters.targetPrivatename) ) &&
( (descriptor.targetSurename == false) || (descriptor.targetSurename ==
$cmt.sentenceFilters.targetSurename) ) &&
( (descriptor.targetFullname == false) || (descriptor.targetFullname ==
$cmt.sentenceFilters.targetFullname) ) &&
( (descriptor.requesterPrivatename == false) ||
(descriptor.requesterPrivatename ==
$cmt.sentenceFilters.requesterPrivatename) ) &&
( (descriptor.requesterSurename == false) || (descriptor.requesterSurename
== $cmt.sentenceFilters.requesterSurenamename) ) &&
( (descriptor.requesterFullname == false) || (descriptor.requesterFullname
== $cmt.sentenceFilters.requesterFullname) ) &&
( (descriptor.time == false) || (descriptor.time ==
$cmt.sentenceFilters.time) ) &&
( (descriptor.subject == false) || (descriptor.subject == $cmt.subject) )
))
then
end
rule "Iphone targets information update - QUERY_AVAILABILITY" extends
"filter sentences based on existence of attributes"
when
$qc: IPhoneQueryCmd(State.POPULATE == state, $tid:
targetId)
$cm: ConditionMatrix($taskId: taskId,
targetId ==
$tid,
contextIntention
== EContextIntention.QUERY_AVAILABILITY,
$timeConstraintType: requesterConstraint.constraintRequestType)
$targetResponse: ArrayList()
from collect
(IPhoneSentences.Sentence(descriptor.intentions.intention contains
EContextIntention.QUERY_AVAILABILITY.name)
from $attributeFilteredSentences)
then
//do something
End
This works fine but once I wish to add a second filtered ArrayList using
$attributeFilteredSentences I get a null pointer exception.
For example I will add an exact similar filter condition but change the
result var name (I called it $dummyVar)
rule "Iphone targets information update - QUERY_AVAILABILITY" extends
"filter sentences based on existence of attributes"
when
$qc: IPhoneQueryCmd(State.POPULATE == state, $tid:
targetId)
$cm: ConditionMatrix($taskId: taskId,
targetId ==
$tid,
contextIntention
== EContextIntention.QUERY_AVAILABILITY,
$timeConstraintType: requesterConstraint.constraintRequestType)
$targetResponse: ArrayList()
from collect
(IPhoneSentences.Sentence(descriptor.intentions.intention contains
EContextIntention.QUERY_AVAILABILITY.name)
from $attributeFilteredSentences)
$dummyVar: ArrayList()
from collect
(IPhoneSentences.Sentence(descriptor.intentions.intention contains
EContextIntention.QUERY_AVAILABILITY.name)
from $attributeFilteredSentences)
then
//do something
End
In this case I get the following exception stack:

The ride's real fun :)
Got apache harmony's beans.jar to work .. now , when I am reading the serialized knowledgebase object on android, quite obvious, it is throwing this error -
java.lang.UnsupportedOperationException: can't load this type of class file
since my serialized knowledgebase object is in java format .. and not dex. Can this serialized version be converted into .dex format using the "dx" utility - pre or post serialization ? I tried the "dx" tool on the serialized object, but it doesn't seem to understand the format.

That's exactly what I am trying out at the moment .. option - b. Pre-compile, serialize and unserialize ...I'll share the results.
Also rule file's there at the location mentioned. So that's not a problem.
I've gone through the blog you mentioned ... and as you indicated, it's only jbpm .. no rules ...

Preparing to be shouted down, but isn't it impossible to compile DRL on Android and the suggestion is to load pre-serialised KnowledgeBases?
Also, as another observation, are you sure the DRL was indeed found and the NPE is not caused by "com.ts.DBconnector.readKnowledgeBase(DBconnector.java:143)" perhaps passing a null to KnowledgeBuilder?
Have you looked at http://blog.athico.com/2011/03/jbpm5-lightweight-running-on-android.html, which might give some pointers - although it is only jBPM and not rules themselves.
With kind regards,
Mike

You might try this:

props.put( "drools.dialect.java.compiler", "JANINO" );
KnowledgeBuilderConfiguration kbConfig =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration( props, (ClassLoader[]) null );
Requires the janino jar in your classpath, which I have as

upon drilling down for the error, found out that it is not able to set the context's dialect.
ctr.getDialect(pkgRegistry.getDialect()) gives "null" ...
DialectCompiletimeRegistry ctr = pkgRegistry.getDialectCompiletimeRegistry();
RuleBuildContext context = new RuleBuildContext(this, ruleDescr, ctr, pkg, ctr.getDialect(pkgRegistry.getDialect()));
Is there any default setting /configuration that I am obviously missing ?
what could be the problem ?

Which version of drools is this?
For drools 5.0.1 we just use maven to resolve the dependencies for us and it works fine. I can't obviously see any eclipse compiler in the jars that we distribute with our application.

Drools 5.2.0.M2 is not compatible with JDK 1.5?
by style.x7
Hi all,
I'm just trying out the default Drools project created with Eclipse plugin
but already getting errors:

peekLast() is a JDK 1.6 method.. so does that means from Drools 5.2x
onwards, I have to upgrade my JDK? Which sadly I can't cause my company is
using OSX Leopard, stuck with JDK 1.5 :(

RuleML 2011 @ BRF Paper Deadline June 21st
by Adrian Paschke
CALL FOR PAPERS
RuleML2011 at BRF
5th International Symposium on Linked Rules: Research-Based,
Industry-Focused
Westin Diplomat, Ft. Lauderdale, Florida, 3-5 November 2011
http://2011.ruleml.org/america
FIRM Extended DEADLINE for paper submission: June 21
Following many requests for an extension of the RuleML at BRF deadline, the
Program committee has decided that 21st June 2011, will be the latest date
on which full papers can be submitted: Note that this deadline cannot be
further extended, since the PC needs to have the time for a good review
process.
Prior submission of abstracts is no longer required.
About RuleML 2011 at BRF
---------------------
In 2011, two installments of the RuleML Symposium will take place. The first
one will be held in conjunction with IJCAI 2011 in Barcelona, Spain, in
July.
The second one will be co-located with the Business Rule Forum to be held in
early November in Ft. Lauderdale, Florida, USA. The second instalment will
include the RuleML Challenge Award which, this year, is dedicated to Rules
and Ontologies.
Objectives
----------
RuleML-2011 at BRF is a research-based, industry-focused symposium:
its main goal is to build a bridge between academia and industry in
the field of rules and semantic technology, and so to stimulate
the cooperation and interoperability between business and research,
by bringing together rule system providers,
participants in rule standardization efforts, open source communities,
practitioners, and researchers. The concept of the symposium has also
advanced continuously in the face of extremely rapid progress in
practical rule and event processing technologies. As a result,
RuleML-2011 will feature hands-on demonstrations and challenges
alongside a wide range of thematic tracks. It will thus be an exciting
venue to exchange new ideas and share experiences
on all issues related to the engineering, management, integration,
interoperation, and interchange of rules in distributed enterprise
intranets and open environments alike.
Topics
--------
As in the previous years, the Symposium will be organized in tracks:
specifically, the RuleML-2011 at BRF focus will be on the following areas:
*** Rules, Semantic Technology, and Cross-Industry Standards
*** Rules and Automated Reasoning
*** Rule-Based Distributed/Multi-Agent Systems
*** Rule Transformation and Extraction
*** Vocabularies, Ontologies, and Business rules
*** NIEM and Rules
*** Cloud Computing and Rules
*** Clinical Semantic and Rules
*** Fuzzy Rules and Uncertainty
*** Rules and Norms
*** Rule-Based Policies, Reputation and Trust
*** Rule-based Event Processing and Reaction Rules
*** General Topics
Submissions on general rule topics are welcome, such as:
- Progress in rule language specification (in XML Schema, Relax NG, etc.)
- Implemented tools for rule bases (e.g. XML and RDF rule validators)
- Rule interchange and reasoning
- Execution models, rule engines, and development environments
- Graphical processing, modeling and rendering of rules
- Rules and NLP
- Rule-based applications
- Usability and effectiveness of rule-based systems and languages
Case studies, experience reports, and industrial problem statements are
particularly encouraged.
RuleML-2011 Challenge
---------------------
The RuleML-2011 Challenge is one of the highlights of RuleML-2011.
Prizes will be awarded to the two best applications, one for the
focus theme and one for the other categories.
This year, the Challenge will be focused on the theme:
***Combining Rules, Objects, and Ontologies: Implementations and
Applications***
The call for demos is available on:
http://2011.ruleml.org/america/challenge
Submission Guidelines
---------------------
Authors are invited to submit original contributions of practical relevance
and technical rigor in the field, experience reports and show case/use case
demonstrations of effective, practical, deployable rule-based technologies
or
applications in distributed environments. Papers must be in English and may
be submitted at
https://www.easychair.org/conferences/?conf=ruleml2011brf
Please upload all submissions as PDF files in LNCS format
(http://www.springer.de/comp/lncs/authors.html).
The selected papers will be published in book form in the Springer Lecture
Notes in Computer Science (LNCS) series.
The selected demo papers will be published in CEUR proceedings.
Important Dates
---------------
Paper submission: June 21, 2011 (11:59PM, UTC-12)
Notification to authors: July 18, 2011
Camera-ready copy due: August 8, 2011
RuleML-2010 Challenge Demos submission: Sept. 2, 2011
RuleML-2011 dates: Nov 3-5, 2011

Why is Drools called "Drools"?
by John Peterson
This is something I get asked on a semi-regular basis and I don't have a good answer for it, so I thought I'd post it to the mailing list and hope someone can tell the story. Is there anyone out there who can explain how the name "Drools" was settled on?

Using multiple Collect() From result in null pointer exception
by Hezi Stern
I have encountered the following issue when running a rule that has more
than 1 collect from a same collection.
I have the following two rules:
rule "filter sentences based on existence of attributes"
when
IPhoneQueryCmd(State.POPULATE == state,
$tidt: targetId)
$attributeFilteredSentences: ArrayList()
from collect (IPhoneSentences.Sentence(
( (descriptor.targetPrivatename == false) || (descriptor.targetPrivatename
== $cmt.sentenceFilters.targetPrivatename) ) &&
( (descriptor.targetSurename == false) || (descriptor.targetSurename ==
$cmt.sentenceFilters.targetSurename) ) &&
( (descriptor.targetFullname == false) || (descriptor.targetFullname ==
$cmt.sentenceFilters.targetFullname) ) &&
( (descriptor.requesterPrivatename == false) ||
(descriptor.requesterPrivatename ==
$cmt.sentenceFilters.requesterPrivatename) ) &&
( (descriptor.requesterSurename == false) || (descriptor.requesterSurename
== $cmt.sentenceFilters.requesterSurenamename) ) &&
( (descriptor.requesterFullname == false) || (descriptor.requesterFullname
== $cmt.sentenceFilters.requesterFullname) ) &&
( (descriptor.time == false) || (descriptor.time ==
$cmt.sentenceFilters.time) ) &&
( (descriptor.subject == false) || (descriptor.subject == $cmt.subject) )
))
then
end
rule "Iphone targets information update - QUERY_AVAILABILITY" extends
"filter sentences based on existence of attributes"
when
$qc: IPhoneQueryCmd(State.POPULATE == state, $tid:
targetId)
$cm: ConditionMatrix($taskId: taskId,
targetId ==
$tid,
contextIntention
== EContextIntention.QUERY_AVAILABILITY,
$timeConstraintType: requesterConstraint.constraintRequestType)
$targetResponse: ArrayList()
from collect
(IPhoneSentences.Sentence(descriptor.intentions.intention contains
EContextIntention.QUERY_AVAILABILITY.name)
from $attributeFilteredSentences)
then
//do something
End
This works fine but once I wish to add a second filtered ArrayList using
$attributeFilteredSentences I get a null pointer exception.
For example I will add an exact similar filter condition but change the
result var name (I called it $dummyVar)
rule "Iphone targets information update - QUERY_AVAILABILITY" extends
"filter sentences based on existence of attributes"
when
$qc: IPhoneQueryCmd(State.POPULATE == state, $tid:
targetId)
$cm: ConditionMatrix($taskId: taskId,
targetId ==
$tid,
contextIntention
== EContextIntention.QUERY_AVAILABILITY,
$timeConstraintType: requesterConstraint.constraintRequestType)
$targetResponse: ArrayList()
from collect
(IPhoneSentences.Sentence(descriptor.intentions.intention contains
EContextIntention.QUERY_AVAILABILITY.name)
from $attributeFilteredSentences)
$dummyVar: ArrayList()
from collect
(IPhoneSentences.Sentence(descriptor.intentions.intention contains
EContextIntention.QUERY_AVAILABILITY.name)
from $attributeFilteredSentences)
then
//do something
End
In this case I get the following exception stack:
