[rules-users] Drools Flow - UI Flow
Hello, I am seeking for ideas: for my current project, we have the requirement to externalize the business and the sequence of steps of a web flow. Example: Online banking: money transfer from account A to account B. Step1: gather transfer data from user. - GOTO Step2. Step2: route: IF amount = 250$ GOTO Step3 ELSE GOTO Step4. Step3: electronic signature - GOTO Step4. Step4: commit to backend. Added value: - We can plug any view technology we want on the UI steps. - Interaction with the backend is not in the view. - Business guys are able to reorder the steps, change the routing logic,... I developed a small proof of concept with Spring Webflow 2 for all the UI steps (Step 1, 3) and Drools Flow as 'flow controller'. It works quite well in the same JVM. But we also want Drools Flow to be on a remote server (+possibly clustering).. There I am stuck because I need our custom WorkItemHandler to start the UI. So, dear community, 1. do you think a flow engine is appropriate for what we are trying to do ? 2. how to manage the 'remote' requirement ?

Here is a method cut pasted from working code in a validation class used
by some of my unit tests. I think it does what you are asking.
private ValidationResult addDrlToKnowledgeBase(String
drlAsString )
{
ValidationResult retval = null;
try
{
KnowledgeBuilder kBuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
Reader rdr = new
StringReader(drlAsString);
Resource resource =
ResourceFactory.newReaderResource(rdr);
kBuilder.add(resource,
ResourceType.DRL);
if (kBuilder.hasErrors())
{
retval =
ValidationResult.newInstance(DRL errors: +
kBuilder.getErrors().toString(), null, null);
}
else
{
knowledgeSession.getKnowledgeBase().addKnowledgePackages(kBuilder.getKnowled
gePackages());
retval =
ValidationResult.newInstance();
}
}
catch(Exception ex)
{
retval =
ValidationResult.newInstance(ex.getMessage(), null, ex);
}
return retval;
}
The type of the instance variable knowledgeSession is
StatefulKnowledgeSession. Ignore the class ValidationResult, it is a
custom class used for returning results from this validation helper class.
Hope this helps.

Subject: [rules-users] Programatically adding rules
toKnowledgeBase/StatefulKnowledgeSession
Hello all,
I'm trying to add rules through my java code to a KnowledgeBase and I cannot
find any easy way to do so. So far, the only solution I could think of, is
to write the rule as DRL in a file that is observed by a KnowledgeAgent
(same with a RuleAgent I suppose). Is it possible to create a new
KnowledgePackage with the same name as the existing one and load it into the
KnowledgeBuilder?
I manage to remove rules using the following code:
statefulKnowledgeSession.getKnowledgeBase().removeRule(knowledgeSetName,
ruleName);
I thought that there would be a addRule method somewhere but not luck so
far.
The code I'm using to create my KnowledgeBase and StatefulKnowledgeSession
is shown below.
All the best,
Pierre
StatefulKnowledgeSession creation code:
StatefulKnowledgeSession ksession;
KnowledgeBuilder kbuilder;
KnowledgeBase kbase;
kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add(ResourceFactory.newFileResource(Demo.class.getResource(Demo.drl
File).getPath()), ResourceType.DRL);
if (kbuilder.hasErrors()) {
System.out.println(kbuilder.getErrors());
}
kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages(kbuilder.getKnowledgePackages());
ksession = kbase.newStatefulKnowledgeSession();
ksession.insert(.);
.
ksession.fireAllRules();

Re: [rules-users] drools gwt-console issues
For issue #1 it can be solved by following the steps below, please note that drools technologies used are 5.1 as downloaded from the default download link of the site (unfortunately was not able to use the lastSuccessfulBuild from https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/ , since i was led to mix match between versions to make it work related post http://drools-java-rules-engine.46999.n3.nabble.com/drools-flow-5-2-0-SNAPSHOT-td1916429.html ) 1. export bpmn flow created in eclipse as png from eclipse (look in the toolbar) and name it id of flow.png 2. place png file inside drools-gwt-graph-5.1.1.jar of the deployed gwt-console-server-drools.war (you will see an already existing com.sample.evaluation.png) 3. at this point it should work right away but it is necessary to include the BPMNDISemanticModule which is not included/used when building in guvnor a package (i.e. the defaultPackage) that includes the previously created workflow. So, either edit the org.drools.guvnor.server.builder.BRMSPackageBuilder.java by adding the line pkgConf.addSemanticModule(new BPMNDISemanticModule()); right after the line pkgConf.addSemanticModule(new BPMNSemanticModule()); . There is probably a more elegant way (which i have not tried it yet) by defining the BPMNDISemanticModule into a BPMNDISemanticModule.conf and seting its path in the property semanticModules inside the drools.default.packagebuilder.conf within the drools-compiler-5.1.1.jar of guvnor.war , this way it is possible to add as many semanticmodules as needed. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/drools-gwt-console-problems-tp1883084p1929866.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users

Re: [rules-users] Building a rule base from the content of a directory
Hi, Many thanks for you answer! Are you talking about DroolsCompilerAntTask and DroolsVerifierAntTask Ant tasks (that I discovered after having read you email)? I've taken a look at the code of the DroolsCompiler task (Drools 5.1.1) and it also concatenates (into a single string) the package file and the BRL file (transformed into DRL) before adding it to the KnowledgeBuilder. The code comes along with the following comment: // TODO: Right now I have to first change this to String. Change to // use KnowledgeBuilder directly when the support for that is done. // -Toni Rikkola- I really wonder if there is a more straighforward way to handle that package file + BRL file association. This is quite fair however compared to the following case: the Drools RCP plugin enables to create rule resources, either rule packages (a DRL file with package, import, globals...) in a single DRL file, or individual rules in a single DRL file as well. An individual rule seems to be kinda like a BRL file: something without any package, import, globals... and with one rule. The problem is I don't see a clever way (when listing the content of a directory) to make the distinction between individual rules and rule packages. For the moment I tend to think that, like in Guvnor UI, the solution is to have conventions (this directory contains individual rules, that directory contains rule packages, that one business rules...).

[rules-users] pass parameters when starting process on gwt-console-server
Hello everyone!!
Is it possible to pass parameters to gwt-console-server when starting a
process??
From code I noticed that calling the service
/gwt-console-server/rs/process/definition/{id}/new_instance , the class
org.jboss.bpm.console.server.ProcessMgmtFacade does not accept parameters
and only calls
instance = getProcessManagement().newInstance(definitionId); which gives
null for parameters in startProcess(..) method.
So, is there a service that accepts parameters when starting a process?
Is it possible to access the knowledge session used by the
gwt-console-server in order to pass parameters ?
Is there some other way maybe??i.e. adding a fact to the working memory?
Initially if it is possible I would prefer to avoid editing any code i.e.
ProcessMgmtFacade or DroolsFlowCommandDelegate
I would appreciate any help, comments and suggestions
thank you for your time

This may or may not answer your question, but with regards to #2, I've been easily able to convert my project based on Facts to Events by simply adding this to one of the DRL files (I used drools.package): declare NumericFact // This is an already defined proper Java class @role( event ) @timestamp( date ) // property defined in class with getter and setter for my needs (historical data) @expires( 365d ) // for my needs end And in my code to process streamed events: KnowledgeBaseConfiguration config = KnowledgeBaseFactory.newKnowledgeBaseConfiguration(); config.setOption( EventProcessingOption.STREAM ); kbase = KnowledgeBaseFactory.newKnowledgeBase(config); Note that facts have to be inserted chronologically with STREAM.

On Thu, Nov 18, 2010 at 3:41 AM, melc c_me...@yahoo.com wrote: For issue # 2 it seems that in order for gwt-console to display the current state of the guvnor package after build, the StatefulKnowledgeSession object ksession in org.drools.integration.console.DroolsFlowCommandDelegate will have to be reinitialised i.e. from method getSession(), but this never happens whether pressing the refresh button or logging out and back in as different user etc the ksession is never null and calling getSession() never calls ksession = newStatefulKnowledgeSession(); . So the question is how to achieve this without touching the code, is there some configuration that would force that after refresh or log out/in of a user in order to display the latest state of guvnor? If not and the code is changed to always initialize the session within method getSession() , would there be a considerable impact in performance ? I appreciate any help, thank you for your time. -- View this message in context: http://drools-java-rules-engine.46999.n3.nabble.com/drools-gwt-console-problems-tp1883084p1920158.html Sent from the Drools - User mailing list archive at Nabble.com. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
