PostGIS Drools Integration
by Matt Shaw
Hi,
We have a system which streams data containing geospatial information that
represents aircraft into a PostGIS database where we also store geographic
areas of interest. We would like to create, with Drools, rules which
utilise the PostGIS geospatial functions as part of the Rules that we
develop.
What would be the most effecient and effective way of integrating the data
that is in PostGIS and the geospatial functions to create facts and rules??
We don't really want to load all that data into memory and would like to
utilise the geospatial functions as they are a very effecient way of
evaluating the data.
Regards
Matt

No matching property definition found after migration
by mrben
Hi,
Just migrated from Guvnor 5.1.1 to Guvnor 5.3.0 on Tomcat 6.0.29. Everything
went fine, except when I logint to my account I get this error message:
400 javax.jcr.nodetype.ConstraintViolationException: no matching property
definition found for {http://www.jboss.org/drools-repository/1.0}workspace
Here is catalina.out:

ruleflow
by gianfranco
I'm wondering if it possible to specify rules file names directly in the flow
(.rf) file.
To explain myself better:
now i have something like :
...
1)KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
2)kbuilder.add(ResourceFactory.newReaderResource(new InputStreamReader(
RuleUtils.class.getResourceAsStream(flowName))),
ResourceType.BPMN2);
3)for (String s : rules)
kbuilder.add(ResourceFactory.newReaderResource(new
InputStreamReader(
RuleUtils.class.getResourceAsStream(s))),
ResourceType.DRL);
...
i would like to skip the step 3, cause I'm working on a generic web service
implementation to execute rules,then
i don't know in advance how many rules i got, they name, etc.
Cheers,
Gianfranco

Facing problem in ResourceChangeScanner
by Saurabh
Hi ,
I am trying to understand KnowledgeAgent functioality.
but i am facing following issue
ResourceChangeScanner is scanning the change resource and building the
Knowledgebase but still firing previous rules.
I am using these line of codes
File fxml = new File("change-set.xml");
kbase = KnowledgeBaseFactory.newKnowledgeBase();
ResourceChangeScannerConfiguration sconf =
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty("drools.resource.scanner.interval", "2");
ResourceFactory.getResourceChangeScannerService().configure(sconf);
KnowledgeAgentConfiguration aconf =
KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
aconf.setProperty("drools.agent.scanDirectories", "true");
aconf.setProperty("drools.agent.useKBaseClassLoaderForCompiling", "true");
aconf.setProperty("drools.agent.scanResources", "true");
aconf.setProperty("drools.agent.newInstance", "true");
KnowledgeAgent kagent = KnowledgeAgentFactory.newKnowledgeAgent("test
agent", kbase, aconf);
System.out.println("test agent:" + kagent.getName());
kagent.applyChangeSet(ResourceFactory.newUrlResource(fxml.toURI().toURL()));
ksession =
kagent.getKnowledgeBase().newStatefulKnowledgeSession();
Thanks ,
Saurabh

Re: [rules-users] Complexity Conflict Resolver not working as expected
by FrankVhh
Hi,
To my knowledge, conflict resolvers are only used to determine priority of
rule activations. It does not prevent rules from firing.
You should be able to get the behavior you want by adding activation-groups.
In an activation group, only one rule can fire. See documentation.
Regards,
Frank
