Drools Flow: a few questions
by HMandic
Hi, I have two questions regarding flow and human tasks.
First, how do you populate ActorId field in Human task at runtime?
The thing is that I don't know which users are potential owners of a task
when the process is started. Could I call a method that populates actors in
OnEntryAction of a human task?
And could someone give me an example how to do it, maybe a code snippet?
(Not how to call a method, but how to get its result and put it in ActorId
field.)
And second, if I don't use the OnEntryAction approach, how can I access that
task before any of the potential users are inserted into it?
A code snippet would also be greatly appreciated, something like:
<code>
ksession.getProcessInstance().getTask(someIdentifier).setActorId("user1,user2");
</code>

Rules "if one of element of this array has ... "
by Maxime Terrettaz
Hi,
I have OUL_R21 facts which have a array of OUL_R21_ORDER_OBSERVATION
objects.
OUL_R21_ORDER_OBSERVATION object has a array of OUL_R21_OBSERVATION.
OUL_R21_OBSERVATION object has a array of OUL_R21_OBSERVATION_RESULT.
And OUL_R21_OBSERVATION_RESULT has a OBX child.
I want to add the number one in my global list if one of all OBX has
abnormalFlags.value in ( 'HH', 'LL', 'AA', 'H', 'L', 'A' )
if
(OUL_21.ORDER_OBSERVATIONS[*].OBSERVATIONS[*].OBSERVATION_RESULTS[*].OBX.abnormalFlags.value
in ( 'HH', 'LL', 'AA', 'H', 'L', 'A' )){
list.add(1);
}
Here is the rule in tring to create...

Problem with the Decision table
by Manikandan
Hi
Below is the code i use to run the rules in the decision table. I am
inserting the empty even object into the session but i still get the "Cannot
be resolved issues". I have attached my decison table as well. Am new to
DRools, so please help.
---------------------------------------------------------------------------------------------------------------------------------------------------------------------
DecisionTableConfiguration dtableconfiguration = KnowledgeBuilderFactory.*
newDecisionTableConfiguration*();
dtableconfiguration.setInputType( DecisionTableInputType.*XLS* );
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.*newKnowledgeBuilder*();
kbuilder.add( ResourceFactory.*newClassPathResource*(
"RFC36877ScenarioDT.xls",
getClass() ),
ResourceType.*DTABLE*,
dtableconfiguration );
*if* ( kbuilder.hasErrors() ) {
System.*err*.print( kbuilder.getErrors() );
*return* -1;
}
KnowledgeBase kbase = KnowledgeBaseFactory.*newKnowledgeBase*();
kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() );
// typical decision tables are used *statelessly
*
StatelessKnowledgeSession ksession = kbase.newStatelessKnowledgeSession();
//now create some test data
Input input = *new* Input();
System.*out*.println("creating the event...");
BusinessEvent event = *new* BusinessEvent();
ksession.execute( Arrays.*asList*( *new* Object[]{input, event} ) );
System.*out*.println( "Business events " + event.getEvents());
*return* 0;

4th International Workshop on Event-Driven Business Process Management
by Adrian Paschke
[ our apologies should you receive this message more than one time ]
4th International Workshop on Event-Driven Business Process Management
collocated with BPM 2010
Hoboken, NJ, USA from September 13-16, 2010
http://www.bpm2010.org/conference-events/workshops/edbpm10/
Introduction
--------------------------
The recently coined term «Event-Driven Business Process Management» (EDBPM)
is nowadays an enhancement of BPM by new concepts of Service Oriented
Architecture (SOA), Event Driven Architecture (EDA), Software as a Service
(SaaS), Business Activity Monitoring (BAM) and Complex Event Processing
(CEP). In this context BPM means a software platform which provides
companies the ability to model, manage, and optimize these processes for
significant gain. As an independent system, CEP is a parallel running
platform that analyses and processes events. The BPM- and the CEP-platform
correspond via events which are produced by the BPM-workflow engine and by
the if distributed - IT services which are associated with the business
process steps. Also events coming from different event sources in different
forms can trigger a business process or influence the execution of a process
or a service, which can result in another event. Even more, the correlation
of these events in a particular context can be treated as a complex,
business level event, relevant for the execution of other business processes
or services. A business process arbitrarily fine or coarse grained can
be seen as a service again and can be choreographed with other business
processes or services, even between different enterprises and organizations.
Loosely coupled event-driven architecture for BPM provides significant
benefits:
* Responsiveness. Events can occur at any time from any source and
processes respond to them immediately, whenever they happen and wherever
they happen.
* Agility. New processes can be modeled, implemented, deployed, and
optimized more quickly in response to changing business requirements.
* Flexibility. Processes can span heterogeneous platforms and
programming languages. Participating applications can be upgraded or changed
without breaking the process model.
Workshop Themes
--------------------------
Authors are invited to submit novel contributions in the prior described
problem domain.
* Event-driven BPM: Concepts
o Role of event processing in BPM
o Business Events: types and representation
o Event stream processing in business processes
o Data- and event-driven business processes
o Evaluation/ROI of event-driven BPM
o Event-driven SOA
o EDA and BPM
o Real/time awareness in BPM
o Context in BPM
* Design-time CEP and BPM
o Modelling languages, notations and methods for event-driven BPM
o Event Patterns: Definition / Creation / Representation /
Learning
o BPMN and event processing
o Modelling unknown/similar events in business processes
o Modelling events in human-oriented tasks
o Semantics/Ontologies for event-driven BPM
o Publish/subscription mechanism and process modelling
* Run-time CEP and BPM
o Event pattern detection
o BPEL and event processing
o Reasoning about unknown/similar events
o Distributed event processing
o Dynamic workflows
o Ad-hoc workflows
* Applications/Use cases for event-driven BPM
o Event-driven monitoring/BAM
o Event-driven SLA monitoring
o Domains: Logistics, Automotive,
o Event processing and Internet of Services
Workshop Format
--------------------------
The Workshop is planned as a full-day event, including a keynote, paper
presentations, lightning talks, demos, posters, and a moderated, open
discussion with the clear goal of agreeing upon a research roadmap for
event-driven Business Process Management research, by taking into account
new challenges, described earlier.
A possible agenda:
* 9:00 9:30 Opening and Keynote
* 9:30 13:00 Paper Presentations
* 13:00 14:00 Lunch
* 14:00 15:00 Lightning Talks
* 15:30 17:00 Moderated Community Discussion: A Roadmap for
Event-driven Business Process Management Research
* 18:00 21:00 Poster and Demo Presentations and Get-Together
For the keynote, we aim at a high-profile speaker, who will give a rather
visionary view on the role of Future Internet for BPM and vice versa. For
the moderated community discussion, we will have senior experts from our
Program Committee and Experts from an industrial background. A clear
objective of that discussion is to yield a first draft of a respective
research agenda.
Important Dates
--------------------------
Deadline paper submissions: 21 May 2010
Notification of acceptance: 30 June 2010
Camera-ready papers: 25 July 2010
Workshops: 13 September 2010
Submission
--------------------------
The following types of submission are solicited:
* Long paper submissions, describing substantial contributions of novel
ongoing work. Long papers should be at most 12 pages long.
* Short paper submissions, describing work in progress. These papers
should be at most 6 pages long.
* Use case submission, describing results from an edBPM use case. These
papers should be at most 4 pages long.
Papers should be submitted in the new LNBIP format
(http://www.springer.com/computer/lncs?SGWID=0-164-7-487211-0). Papers have
to present original research contributions not concurrently submitted
elsewhere. The title page must contain a short abstract, a classification of
the topics covered, preferably using the list of topics above, and an
indication of the submission category (Long Paper/ Short Paper).
For submission, please visit
http://www.easychair.org/conferences/?conf=edbpm10.
