Creating a business process programatically, Jbpm5 tutorials for beginners
by Ahmed Feki
Hi,
i m a jbpm5 beginner and i m reading the Drools Developer's Cookbook
-[Packt Publishing, Jan 2012] and on its chapter 9 :"jBPM5: Managing
,Business Processes" there is a sample project for Creating a business
process manually (creating-process-using-the-api) in i which there is an
EventNode instanciation :
EventNode eventNode = new EventNode();
eventNode.setName("EventNode");
eventNode.setId(2);
eventNode.setScope("external");
EventTypeFilter eventFilter = new EventTypeFilter();
eventFilter.setType(eventType);
eventNode.addEventFilter(eventFilter);
i want to understand what the "eventNode.setScope("external");" means and
also about filters.
i googled for the jbpm-flow-builder API but didnt find any documentation.
i dont know where to find some tuorials for these stuffs..
thnx for help !

drools 5.0's RuleFlow & drools 5.2's jbpm5
by bardelman
Hi,
i m planning to learn jbpm5 and i ve 2 books :
-Drools-JBoss-Rules-5.0-Developers-Guide :which is about the version 5.0 of
drools. in this book, there is a chapter about the Drools flow.
-The second book is the Drools Developper Cookbook(2012), here there is a
chapter about the jbpm5 in which it s said :<<jBPM5 is the new brand name of
the Drools process engine that was previously known as
Drools Flow.>>
As i want to optimize my learning curve for this framework(i mean for jbpm5)
i want to know if it is useful to read from the first book ? is it still
useful the Drools flow of the version 5.0 ? sorry for my bad english ..!!

Visualizing production rules metrics in 3D
by Jackson Cunha
Hi for all and sorry for any duplication.
My team are starting a project where we will develop a tool to visualize
metrics of a production rule base and show them in a 3D form.
Through this tool we want measure quality and conformity with good
practices to help in detection of anomalies and ensure a good design of a
knowledge base.
Other tools and studies already exists to visualize code and calculate
metrics from java code. Examples are CodeCity (
http://www.inf.usi.ch/phd/wettel/codecity.html<http://www.linkedin.com/redirect?url=http%3A%2F%2Fwww%2Einf%2Eusi%2Ech%2F...>),
where java code is visualized using a city metaphor and Sonar where metrics
are extracted from source code to help in code quality assurance (
http://nemo.sonarsource.org/dashboard/index/327690<http://www.linkedin.com/redirect?url=http%3A%2F%2Fnemo%2Esonarsource%2Eor...>
).
So, my questions is:
1 - How much relevant you think this idea is?
2 - You know about other research in this area?
Thanks in advance.

Ws-Policy and drools rules
by FILIPPO AGAZZI
Hi,
i'm Filippo Agazzi, from University of Parma, and i'm working on a thesis
work, where i'm evaluating if Drools Expert(rule engine) can fit my needs.
I'm trying to use drools engine in web services environment.
My problem is that i have to translate in some way, Ws-Policy (xml format),
containing for example a request for client to send x509 element, received
in SOAP message, into drools rules, so i can use this policy as rules for
Drools engine. Drools engine is used to lead a negotation exchange of SOAP
message, containing ws-policy and credentials. Is there anyone that has an
idea of how can i do this translation at runtime? Or how can i insert into
drools engine, my policy element as rules? I can have also a java class
Policy to use, if it can help inserting ws-policy as rules into drools.
Thanks in advance.
Regards,
Filippo Agazzi

Paid Community Support
by dollanitri
1. Is there any paid community support available for the Drools, to support
production systems for the troubleshooting in case of sever failures ?
2. If yes, then could anybody give me link or details to find out cost
details and other stuff related to support ?
3. It would be great if anybody can give or have an idea about how much
charge it will cost to take paid community support for the production
systems ?

getting list of broken constraints for some solution(NOT BEST SOLUTION) in drools-planner
by Nurlan
Hi guys!
I'm using drools-planner-*5.4.0.CR1*...
Let's say I have some solution(NOT FINAL BEST SOLUTION) which done by human
manually and I want get list of broken contraints for that solution, I've
tried
this.scoreDirector.setWorkingSolution(someSolution);
this.scoreDirector.calculateScore();
it returns *null* since it isn't connected with Solver
then I've tried using Solver with
<termination><maximumStepCount>0</maximumStepCount></termination>:
this.scoreDirector.setWorkingSolution(someSolution);
this.solver.setPlanningProblem(this.scoreDirector.getWorkingSolution());
this.solver.solve();
this.scoreDirector.setWorkingSolution(this.solver.getBestSolution());
this.scoreDirector.calculateScore();
then it shows *java.lang.UnsupportedOperationException* because there is no
best solution in Solver
java.lang.UnsupportedOperationException: StepCountTermination can only be
used for phase termination.
at
org.drools.planner.core.termination.StepCountTermination.isSolverTerminated(StepCountTermination.java:40)
at
org.drools.planner.core.termination.OrCompositeTermination.isSolverTerminated(OrCompositeTermination.java:42)
at
org.drools.planner.core.solver.DefaultSolver.runSolverPhases(DefaultSolver.java:181)
at
org.drools.planner.core.solver.DefaultSolver.solve(DefaultSolver.java:151)
how can implement this task? or I have to implement setBestSolution in
Solver, i think this is bad idea...
