Rule Task
by S.M.H.Jamali
Hello All
I create a simple JBPM Process by Eclipse Plugin that starts with a Script Task and after Script Task i want to add a Rule Task. In fact i want to fire a rule in my process to make a decision on the Gate Way node. I use Guvnor and JBPM Console to run my processes and after designing the processes i upload them to Guvnor.
My problem is : when i create a new instance of my process (in jbpm console) , first Script Task run fine , but execution of the process stops at Rule Task and no rule fired ! Am i missing something ?
Any Help Appreciated

Stateful vs. Stateless Session Performance
by Ryan R.
I have a usecase where I want to apply rules to messages that are received
and processed one message at a time.
I am thinking the stateless session matches this usecase. I was surprised
though to notice that the stateless session seemed to perform upwards of 10x
slower!
I am including the below source which illustrates my usage. The DRL file
used simply has one rule that does a simple modification on two fields.
There is some test code above this stuff that just pushes messages into the
plugin.
I am also including VisualVM profiling results. The top results are for the
stateful while the bottom are for the stateless. It looks like the stateless
performance is dominated by calls to ReflectionInstantiator.newInstance()?
StatelessKnowledgeSession Code:
public class DataConditionPlugin implements Plugin {
final KnowledgeBuilder kbuilder;
final StatelessKnowledgeSession ksession;
public DataConditionPlugin(String drlFileName) {
kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
// this will parse and compile in one step
kbuilder.add(
ResourceFactory.newClassPathResource(drlFileName,
DataConditionPlugin.class),
ResourceType.DRL);
// Check the builder for errors
if (kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors().toString());
throw new RuntimeException("Unable to compile \""+drlFileName+"\".");
}
// get the compiled packages (which are serializable)
final Collection<KnowledgePackage> pkgs =
kbuilder.getKnowledgePackages();
// add the packages to a knowledgebase (deploy the knowledge packages).
final KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(pkgs);
ksession = kbase.newStatelessKnowledgeSession();
}
@Override
public Object execute(Object message) {
ksession.execute(message);
return message;
}
}
StatefulKnowledgeSession Code:
public class DataConditionPlugin implements Plugin {
final KnowledgeBuilder kbuilder;
final StatefulKnowledgeSession ksession;
public DataConditionPlugin(String drlFileName) {
kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
// this will parse and compile in one step
kbuilder.add(
ResourceFactory.newClassPathResource(drlFileName,
DataConditionPlugin.class),
ResourceType.DRL);
// Check the builder for errors
if (kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors().toString());
throw new RuntimeException("Unable to compile \""+drlFileName+"\".");
}
// get the compiled packages (which are serializable)
final Collection<KnowledgePackage> pkgs =
kbuilder.getKnowledgePackages();
// add the packages to a knowledgebase (deploy the knowledge packages).
final KnowledgeBase kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(pkgs);
ksession = kbase.newStatefulKnowledgeSession();
}
protected void finalize() throws Throwable {
ksession.dispose();
};
@Override
public Object execute(Object message) {
FactHandle factHandler = ksession.insert(message);
ksession.fireAllRules();
Object o = ksession.getObject(factHandler);
ksession.retract(factHandler);
return o;
}
}

error resolving class name on imported class when loading package
by lhorton
I am getting an error when the knowledge agent loads a pkg. The rules source
file contains an import for a class:
com.abclegal.domain.task.FileDocumentsWithCourtTask
and the RHS of a rule makes a cast using the class name without fully
qualifying it:
((FileDocumentsWithCourtTask)$step.getTask()).addDocument($doc);
I see the following error when the package is loaded by knowledge agent:
Error creating bean with name 'workflowKnowledgeAgent': Invocation of init
method failed; nested exception is [Error: unable to resolve method using
strict-mode: java.lang.Object.FileDocumentsWithCourtTask()]
[Near : {... ((FileDocumentsWithCourtTask)$st ....}]
note in the error that the FileDocumentsWithCourtTask is not being resolved
according to the import statement. The really odd thing about this is that
it doesn't get the error all the time. Sometimes the package is loaded
without error.
I can probably resolve this by fully-qualifying the class name within the
RHS, but you are not supposed to have to do that if you put the
fully-qualified name in the import of the rule.
Any clue why this error might happen?

Not able to get the knowledgeBase from web application
by jilani
Hi,
I am working with Drools 5.2.0 final and Guvnor also the same version.
application server: GateIn-3.1.0-FINAL-jbossas
I have uploaded a java model and defined a rule using that model. I did
validation of the package and build also.
After that in my web application, when I am trying to access the
knowledgebase I am getting error in server console as mentioned below.

Query in stateless knowledge session returns no results
by Heijink, Hank
Hi all,
I'm new to Drools, so please excuse me if I'm asking about the obvious--it's certainly not obvious to me. The problem is this: I use a stateless knowledge session where a list of facts is inserted. The rules that fire create new facts, and after all the rules have fired, I'd like to obtain a list of all the facts (the old and the new). The best way seemed to use a query. I'm using Drools 5.1 on Linux.
This is part of my .drl file (without the imports):
rule "create badge"
when
Event ( eventType == EventType.SOME_EVENT_TYPE )
not BadgeState ( identifier == "badge" )
then
insert( new BadgeState("badge") );
end
query "all badges"
aBadge : BadgeState()
end
This is the Java code:
StatelessKnowledgeSession ksession = StatsKnowledgeBase.getKnowledgeBase().newStatelessKnowledgeSession();
// Create a list of share events
ArrayList<Event> events = new ArrayList<Event>();
Date now = new Date();
MobileDevice aDevice = new MobileDevice("uniqueId", "deviceType");
for (int i = 0; i < 5; i++) {
Event anEvent = new Event.Builder(now, aDevice, "aCustomer", EventType.SOME_EVENT_TYPE).build();
events.add(anEvent);
}
// Create the query for the badges
List<Command> commands = new ArrayList<Command>();
commands.add(CommandFactory.newInsertElements(events));
commands.add(CommandFactory.newQuery("all badges", "all badges"));
// Feed the events into Drools
KnowledgeRuntimeLogger logger = KnowledgeRuntimeLoggerFactory.newConsoleLogger(ksession);
ExecutionResults results = ksession.execute( CommandFactory.newBatchExecution(commands) );
NativeQueryResults queryResults = (NativeQueryResults)results.getValue("all badges");
// At this point, queryResults is empty.
logger.close();
// Get a list of badges
List<BadgeState> badges = new ArrayList<BadgeState>();
for (Iterator<QueryResultsRow> i = queryResults.iterator(); i.hasNext(); ) {
QueryResultsRow result = i.next();
BadgeState obj = (BadgeState)result.get("aBadge");
badges.add(obj);
}
The logger shows me that the BadgeState object is created, but the query returns an empty list. I've searched the documentation, which suggests that I'm doing it right (http://drools.herod.net/drools-expert/html/ch03.html#d0e1956, example 3.37), the archives of this mailinglist, and the web, so far without success.
Clearly, I'm missing something, and I have the nagging feeling that it's something simple...
Any help is much appreciated!
Best,
Hank

CFP: 4th International Workshop on Semantic Web Applications and Tools for the Life Sciences (SWAT4LS 2011)
by Adrian Paschke
Call for Papers
4th International Workshop on Semantic Web Applications and Tools for the
Life Sciences (SWAT4LS 2011)
http://www.swat4ls.org/2011/
Overview
Since 2008, SWAT4LS is a workshop that has provided a platform for the
presentation and discussion of the benefits and limits of applying web-based
information systems and semantic technologies in Biomedical Informatics and
Computational Biology.
Growing steadily each year as Semantic Web applications become more
widespread, SWAT4LS has been in Edinburgh 2008, Amsterdam 2009, and Berlin
2010, with London planned for 2011. The last edition of SWAT4LS was held in
Berlin, on December 10th, 2010. It was preceded by two days of tutorials and
other associated events.
We are confident that the next edition of SWAT4LS will provide the same open
and stimulating environment that brought together researchers, both
developers and users, from the various fields of Biology, Bioinformatics and
Computer Science, to discuss goals, current limits and real experiences in
the use of Semantic Web technologies in Life Sciences.
________________________________________
Rationale
The web is a key medium for information publishing, and web-based
information systems play a key role in biomedical information exchange and
integration. At the same time, the variety and complexity of biomedical
information call for the adoption of semantic-based solutions. The Semantic
Web provides a set of technologies and standards that are key to support
semantic markup, ontology development, distributed information resources and
collaborative social environments. Altogether the adoption of the web-based
semantic-enabled technologies in the Life Sciences has potential impact on
the future of publishing, biological research and medecine. This workshop
will provide a venue to present and discuss benefits and limits of the
adoption of these technologies and tools in biomedical informatics and
computational biology. It will showcase experiences, information resources,
tools development and applications. It will bring together researchers, both
developers and users, from the various fields of Biology, Bioinformatics and
Computer Science, to discuss goals, current limits and some real use cases
for Semantic Web technologies in Life Sciences.
________________________________________
Topics
Topics of interest include, but are not limited to:
. Standards, Technologies, Tools for the Semantic Web
o Semantic Web standards and new proposals (e.g.: RDF, OWL, SKOS, SPIN,
RuleML)
o Tools for ontology management, editing and versioning
o RDF stores, Reasoners, query and visualization systems
o Formal approaches to large biomedical knowledge bases
o Tools for semantic-enabled web publication
o Alternative approaches to integrate semantic representations and web based
solutions
. Systems for a Semantic Web for Bioinformatics
o Biomedical knowledge bases on the Semantic Web

Error with MVEL2 Using Smooks 1.4 and Drools 5.2
by Lavoisier Farias
Hi guys,
I am newbie in this kind of things, but I am facing some difficults to use
Smooks 1.4 an d Drools 5.2. It seams that MVEL2 present in the drools 5.2
distribution is not compatible with Smooks 1.4.
Did anybody have similar problems ?
If a have a separate project, which uses Smooks 1.4, my program is able to
read a CSV file and convert it to Java Bean List, in fact, a Java List.
However, If I use the same structure to read information from a CSV file and
insert hem into a Drools Rule Engine, I got the error right below: Does
anybody know how I can fix that ?
This is my smooks configuration file:

How to add application data via StatefulKnowledgeSession
by Matthew Erler
Can someone please show me an example where application data is added to
workingMemory as described here:
http://docs.codehaus.org/display/DROOLS/Application+Data using
StatefulKnowledgeSession?
I have a need to populate an object from a rules file and I don't want that
object itself to be treated as a rule. All the examples I can find refer to
the use of ruleBase to get workingMemory. My code utilizes
StatefulKnowledgeSession to fire rules and I don't see how to get ruleBase
or workingMemory from it. Thanks.

Using Rule Templates
by David Godfrey
Can someone point me in the direction of documentation or examples for using
Rule Templates together with data held in a database (or source other than
XLS / CSV which seems to be what all the examples show)?
Many thanks,
David

Possibly stupid question... but I have to ask
by Eugenia Carcel
Hi,
Is it possible to insert and modify a fact in the same rule consequence ?
>From what I've read in the docs... it isn't...
If I could do that it would be great for me. This is the reason why I post
this question.
I hope someone will anwer.
