Guvnor Build pkg error.
by Yan Liu
When trying to build a package (even using the sample pkg from drools
Guvnor) I got this - "Sorry, a technical error occurred. Please contact a
system administrator."
This is indeed very frustrating as I need to build binary pkgs for my remote
rule agents to access. I found the post here saying it is fixed.
https://jira.jboss.org/jira/browse/GUVNOR-327 No details though.
Can anyone shed some light on this problem if you know how to fix it?
Thanks in advance for your reply.

Debugging, Tracing and Visualization of rule execution
by Daniel Gebler
For our integration of Drools 5.0 we want to provide end users with limited
technical skills the possibility to debug, trace and visualize the rule
execution as well as the fact base.
Questions that are frequently asked by users as well as by the
development/qa team:
- Did my rule r1 fire for this query?
- Why did rule r1 not fire (i.e. which constraint doesn't match)?
- Which kind of rule dependencies (chaining) do I have in my rule
base? Rule r1 and r2 are dependent iff action of r1 (e.g. publish a fact)
makes constraint of r2 true.
- Which rules need to fire in order to generate the additional fact
f1 in the fact base?
- What is the smallest change in the fact base (additional facts
etc.) in order to make rule r1 to fire (abduction)?
Problems:
- Eclipse plugin doesn't provide information of what didn't happen
and why it didn't happen ( 'Audit' view allows just tracking of positive
cases, i.e. what happened). Furthermore the stability of the eclipse plugin
seems to be limited.
- Integrating over SPI doesn't allow to show the Rete network
because Rete view works only with drl files
- How to provide feedback to a normal end user of the search server
(limited tech skills) about rule-related information?
Solution ideas/approaches + our assessment:
1. Use a run time monitor providing on-demand log trace information
when facts are being published. The log trace provides the information
about which and why a particular constraint is or is not satisfied. Our
initial implementation uses an aspect oriented approach (JBoss AOP) to
gather relevant information. In detail: Our initial implementation uses an
aspect oriented approach (JBoss AOP) to gather the information by
intercepting EntryPointNode.assertObject(), and traversing the rete network
to collect the constraint information for every unique alpha/join node. This
will allow to visualize the log trace (GUI) and interpret the trace in the
context of our product. We discussed this approached in #drools with Edson
Tirelli and he was very interested.
2. Use drools AgendaEventListener. Listener does not gets enough debug
info exposed, esp. we cannot extract the cause to reject a rule. Not enough
information available therefore this one is not an option.
Additionally, it would be nice for our development to also visualize the
Rete-OO network, but that seems to be impossible when integrating drools
directly via the SPI classes. Is there a way to connect the viewer to a
network inside a running VM?
We would like to hear whether you know any other opinions, or have points
how to implement those features. Please share your experience how to bridge
the gap between end-users with limited technical backgrounds expressing and
investigating the rule inference.
Thanks,
Daniel

===================================================================
Overview and Aim
===================================================================
The International Symposium on Rules, Applications and Interoperability has
evolved from an annual series of international workshops since 2002,
international conferences in 2005 and 2006, and international symposia since
2007. This year, the 3rd International Symposium on Rules, Applications and
Interoperability (RuleML-2009) takes place in Las Vegas, Nevada, USA,
collocated with the 12th Business Rules Forum, the world's largest Business
Rules event. RuleML-2009 is devoted to practical distributed rule
technologies and rule-based applications which need language standards for
rules (inter)operating in, e.g., the Semantic Web, Multi-Agent Systems,
Event-Driven Architectures, and Service-Oriented Applications.
The main goal of RuleML-2009 is 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-2009
will feature hands-on demonstrations and challenges alongside a wide range
of thematic tracks, and thus will be an exciting venue to exchange new ideas
and experiences on all issues related to the engineering, management,
integration, interoperation and interchange of rules in open distributed
environments such as the Web.
Conference Theme
===================================================================
This year, we particularly welcome submissions that address applications of
Web rule technologies for business and information systems. We invite you to
share your ideas, results, and experiences: as an industry practitioner,
rule system provider, technical expert and developer, rule user or
researcher, exploring foundations, developing systems and applications, or
using rule-based systems. We invite high-quality submissions related to (but
not limited to) one or more of the following topics:

RuleML-2009 Challenge
===================================================================
The RuleML-2009 Demo Challenge is one of the highlights of RuleML-2009. We
invite submissions of demo papers and demos where rules are used in
interesting and practically relevant ways to, e.g., derive useful
information, transform knowledge, provide decision support and provide
automated rule-based monitoring, enforcement, validation or management of
the behavioural logic of the application. The Challenge offers participants
the chance to demonstrate their commercial and open source tools, use cases,
and applications. Submissions are solicited in these categories:
- Benchmarks (test cases, suites) with evaluations of (their own, other)
rule engines and/or rule translators, possibly drawing on our growing
pool at http://ruleml-challenge.cs.nccu.edu.tw
- Case studies (use cases) implemented via engines/translators employing
rule standards such as RIF, RuleML, CLIPS, Common Logic, SBVR, and ISO
Prolog.
We welcome all demos about tools and applications using rules such as:
- Derivation rules, including query and integrity rules
- ECA rules, including production rules, reaction rules, and rule-based
CEP languages
Authors of demo are also invited to submit a Challenge demo paper for
publications in the conference proceedings, see the submission section below
for submission details.
Prizes will be awarded to the two best applications from each category. All
accepted demos will be presented in a special Challenge Session. A
submission to the RuleML Challenge has to meet the requirement that
declarative rules explicitly play a central role in the application.
Basically this means that:
Rules are explicitly represented in a declarative format and they are
decoupled from the application (rather than being compiled or hard-coded
into the application logic). The demo should preferably (but not
necessarily) be embedded into a web-based or distributed environment so that
there will be a need for features related to the RuleML conference topics,
as listed in the call for papers. For more details and the demo site web
link please consult the RuleML-2009 Challenge website:
http://ruleml-challenge.cs.nccu.edu.tw
Student Grant Awards
===================================================================
Two travel grants are available to students who are authors or co-authors of
papers or demos accepted for presentation at the symposium. The grants
include free registration and cover travel expenses up to 1000 dollars.
Conference Language
===================================================================
The official language of the conference will be English.
Submission
===================================================================
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
http://www.easychair.org/conferences/?conf=ruleml2009
as:
Full Papers (15 pages in the proceedings)
Short Papers (8 pages in the proceedings)
RuleML-2009 Challenge Demo Paper + Show Cases (3-5 pages in the proceedings)
Please upload all submissions as PDF files in LNCS format
(http://www.springer.de/comp/lncs/authors.html). To ensure high quality,
submitted papers will be carefully peer-reviewed by 3 PC members based on
originality, significance, technical soundness, and clarity of exposition.
Authors are requested to upload the abstracts of their papers before June 9,
2009 and to upload their complete papers by June 16, 2009. The selected
papers will be published in book form in the Springer Lecture Notes in
Computer Science (LNCS) series along with a CD with demo software and
documents. The best paper from all submissions will be determined by the PC
and a Best Paper Award will be handed over at the Symposium by a Sponsor.
All submissions must be done electronically. A selection of revised papers
will be resubmitted to a special issue of a journal.
Submissions to the RuleML Challenge 2009 consist of a demo paper of 3-5
pages, describing the demo show case, and a link to more information about
the demo/show case, e.g. a project site, an online demonstration, a
presentation about the demonstration, or a download site for the
demonstration. In case of product demos, the link can be password-protected:
please submit a password for anonymous login from any Web browser, giving us
the permission to pass the password on to 3 PC members. The submissions
should satisfy the minimal requirements defined in the topics of interest
and preferably exhibit some of the additional desiderata. The more
desiderata are met by an application, the higher the score will be. The
demos will be evaluated by the RuleML-2009 Program Committee and prizes will
be awarded to the two best applications, sponsored by the RuleML Inc.
non-profit organization.

Throwing runtimeException 4.0.7 not supposed
by surya_n2007
Throwing runtime exception in this example inserted person object as person
name is null. Ideally need to add error
"P01" and in second rule checks for precondition "P01" exist and skip rule.
But i am getting the below error.
Please let me know this is bug, i dont want to check again "Second Rule"
name object is not null.
I think this is happening since drools frist try to run all rules before
start execution.
please let me know whether anything wrong on my end.

Person person = test.new Person();

Inserting Collection into WorkingMemory
by VinuJay
Hi my fact object looks like this,
class ProcessRequest {
Long requestId;
String processType;
String assigneeUsers;
List<String> businessData;
//Getters and Setters
}
I have inserted the fact object into working memory in this way
WorkingMemory workingMemory = ruleBase.newStatefulSession();
FactHandle factObject = workingMemory.insert(processRequest );
workingMemory.fireAllRules();
My question is how to use the values in the business data for comparison in
the rules.drl file rule "Audit"
when
p: ProcessRequest(processType == "Audit" && SSN == 1234) then
p.setAssigneeUsers("AuditUser1");
end
When i try with the above rule it says no field extractor found for SSN, SSN
is part of the businessdata(List<String>)
Please do suggest me
1. How to make the Workingmemory aware of the Collection - businessData 2.
Change the rules.drl file syntax to access values from Collection.

mvel memory use
by Greg Barton
I've been analyzing the performance of a little side project I'm doing with drools, and I've noticed that mvel churns through a huge number of HashMap creations when evaluating expressions. The main problem is in the org.mvel2.integration.impl.ClassImportResolverFactory constructor, which is called every time org.drools.base.mvel.MVELPredicateExpression.evaluate() is called. (Which is, of course, a LOT.) In my case I'm seeing the vast majority of activity in org.drools.rule.PredicateConstraint.isAllowedCachedRight(), so maybe this is something controllable by changing a rule, but I'm not sure. I've watched literally gigabytes per second of HashMap.Entry objects being created. Is there some way around this? I know this may be a better question for the mvel dev list, but I wanted to bring it to your attention.

has also advanced continuously in the face of extremely rapid progress in
practical rule and event processing technologies. As a result, RuleML-2009
will feature hands-on demonstrations and challenges alongside a wide range
of thematic tracks, and thus will be an exciting venue to exchange new ideas
and experiences on all issues related to the engineering, management,
integration, interoperation and interchange of rules in open distributed
environments such as the Web.
Conference Theme
===================================================================
This year, we particularly welcome submissions that address applications of
Web rule technologies for business and information systems. We invite you to
share your ideas, results, and experiences: as an industry practitioner,
rule system provider, technical expert and developer, rule user or
researcher, exploring foundations, developing systems and applications, or
using rule-based systems. We invite high-quality submissions related to (but
not limited to) one or more of the following topics:

Case studies, experience reports, and industrial problem statements are
particularly encouraged.
RuleML-2009 Challenge
===================================================================
The RuleML-2009 Demo Challenge is one of the highlights of RuleML-2009. We
invite submissions of demo papers and demos where rules are used in
interesting and practically relevant ways to, e.g., derive useful
information, transform knowledge, provide decision support and provide
automated rule-based monitoring, enforcement, validation or management of
the behavioural logic of the application. The Challenge offers participants
the chance to demonstrate their commercial and open source tools, use cases,
and applications. Submissions are solicited in these categories:
- Benchmarks (test cases, suites) with evaluations of (their own, other)
rule engines and/or rule translators, possibly drawing on our growing
pool at http://ruleml-challenge.cs.nccu.edu.tw
- Case studies (use cases) implemented via engines/translators employing
rule standards such as RIF, RuleML, CLIPS, Common Logic, SBVR, and ISO
Prolog.
We welcome all demos about tools and applications using rules such as:
- Derivation rules, including query and integrity rules
- ECA rules, including production rules, reaction rules, and rule-based
CEP languages
Authors of demo are also invited to submit a Challenge demo paper for
publications in the conference proceedings, see the submission section below
for submission details.
Prizes will be awarded to the two best applications from each category. All
accepted demos will be presented in a special Challenge Session. A
submission to the RuleML Challenge has to meet the requirement that
declarative rules explicitly play a central role in the application.
Basically this means that:
Rules are explicitly represented in a declarative format and they are
decoupled from the application (rather than being compiled or hard-coded
into the application logic). The demo should preferably (but not
necessarily) be embedded into a web-based or distributed environment so that
there will be a need for features related to the RuleML conference topics,
as listed in the call for papers. For more details and the demo site web
link please consult the RuleML-2009 Challenge website:
http://ruleml-challenge.cs.nccu.edu.tw
Student Grant Awards
===================================================================
Two travel grants are available to students who are authors or co-authors of
papers or demos accepted for presentation at the symposium. The grants
include free registration and cover travel expenses up to 1000 dollars.
Conference Language
===================================================================
The official language of the conference will be English.
Submission
===================================================================
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
http://www.easychair.org/conferences/?conf=ruleml2009
as:
Full Papers (15 pages in the proceedings)
Short Papers (8 pages in the proceedings)
RuleML-2009 Challenge Demo Paper + Show Cases (3-5 pages in the proceedings)
Please upload all submissions as PDF files in LNCS format
(http://www.springer.de/comp/lncs/authors.html). To ensure high quality,
submitted papers will be carefully peer-reviewed by 3 PC members based on
originality, significance, technical soundness, and clarity of exposition.
Authors are requested to upload the abstracts of their papers before June 9,
2009 and to upload their complete papers by June 16, 2009. The selected
papers will be published in book form in the Springer Lecture Notes in
Computer Science (LNCS) series along with a CD with demo software and
documents. The best paper from all submissions will be determined by the PC
and a Best Paper Award will be handed over at the Symposium by a Sponsor.
All submissions must be done electronically. A selection of revised papers
will be resubmitted to a special issue of a journal.
Submissions to the RuleML Challenge 2009 consist of a demo paper of 3-5
pages, describing the demo show case, and a link to more information about
the demo/show case, e.g. a project site, an online demonstration, a
presentation about the demonstration, or a download site for the
demonstration. In case of product demos, the link can be password-protected:
please submit a password for anonymous login from any Web browser, giving us
the permission to pass the password on to 3 PC members. The submissions
should satisfy the minimal requirements defined in the topics of interest
and preferably exhibit some of the additional desiderata. The more
desiderata are met by an application, the higher the score will be. The
demos will be evaluated by the RuleML-2009 Program Committee and prizes will
be awarded to the two best applications, sponsored by the RuleML Inc.
non-profit organization.
