[rules-users] Drools as osgi bundle in Jboss AS
Hi,
I am trying to run Hello World using drools as osgi bundle in Jboss AS.
Deployed below jars to Jboss container :
drools-compiler-6.0.0.Beta1.jar
drools-core-6.0.0.Beta1.jar
drools-templates-6.0.0.Beta1.jar
kie-api-6.0.0.Beta1.jar
kie-internal-6.0.0.beta1.jar
While deploying my own bundle to Jboss which has Hello World Drools
application, I get below exception:
Caused by: org.drools.RuntimeDroolsException: Unable to load dialect

Then added org.eclipse.jdt.core_3.8.3.v20130121-145325.jar to classpath of

[rules-users] Moves Defined from Current State
I'm using Optaplanner 6.0.1 and I'm having trouble defining a type of move that I'd like to define. In my domain, there may be an opportunity to split the value assigned to one entity across two entities. For example: E1=5could become E2=2, E3=3 The trouble is that in some cases this split can be performed more than one way. The above example could also be split to become E2=1,E3=4, ... At the time that the Moves is created (and initialized with entities) by the MoveFactory, there are values assigned to the entities but those values may change and shouldn't be part of the Move (am I right about that?). So when Moves are executed, the values assigned could be considered to create a set of Moves based on the current state but aren't Moves already created long before then? Is there a way to generate moves based on the current state? How do you ensure they are not cached ore reused after that step?

Re: [rules-users] Drools, slf4j and Eclipse Error on DroolsTest.Java
This isn't my code. It's created when a Drools project is created in
Eclipse. I guess that's why this is so frustrating. It's supposed to
demonstrate a very simple Drools program and I can't get it to work.
It's hard to debug someone else's code when you don't know the language yet.
Code is kSession.insert(message);

Re: [rules-users] Drools 6 and Gradle?
We require jars that are built to conform to maven standards. But they do not need to be built with maven. That means they do need a pom.properties in there. If gradle does not add that automatically, you should be able to automate that yourself. The pom.properties is a very simple file, that requires 3 key value pairs: #Generated by Maven #Wed Nov 18 14:44:09 PST 2009 version=2.2 groupId=javax.el artifactId=el-api This is necessary for discovery of jars, and versioning of jars within the same JVM. Maven provides a standard for this, so it seemed redundant us creating yet another way to declare this meta data.

We are running a simple stress test (whose code I will paste below) for a
numbercompare rule file)
We get the following error before the test finishes. Which seems odd for one
rule
javax.servlet.ServletException: java.lang.OutOfMemoryError: PermGen space
This test is run against 3 loablanced tomcat servers
Here is my JVM_OPTS for each of those tomcat
JVM_OPTS=-Xms4096m -Xmx4096m -XX:NewSize=2048m -XX:PermSize=512m
-XX:MaxPermSize=512m -Xss1024K -XX:+UseCodeCacheFlushing
-XX:-UseSplitVerifier

I have a simple rule file deployed on guvnor on my abc with JVM_OPTS on the
guvnor being
JVM_OPTS=-Xms4096m -Xmx4096m -XX:NewSize=2048m -XX:PermSize=512m
-XX:MaxPermSize=512m -Xss1024K
Here is my stress test that we are running

Here is my rules defined on guvnor
package org.numbercompare;
declare NumberCompare
message : String
numberone: Integer
numbertwo: Integer
end
rule numberone is equals to numbertwo
when
n: NumberCompare(numberone == numbertwo);
then
n.setMessage(numberone is equals to numbertwo);
end
rule numberone is greater than numbertwo
when
n: NumberCompare(numberone numbertwo);
then
n.setMessage(numberone is greater than numbertwo);
end
rule numberone is less than numbertwo
when
n: NumberCompare(numberone numbertwo);
then
n.setMessage(numberone is less than numbertwo);
end
Here is my code that updates the rule file
public KnowledgeBase readKnowledgeBase() throws Exception {
ResourceFactory.getResourceChangeNotifierService().start();
ResourceFactory.getResourceChangeScannerService().start();
ResourceChangeScannerConfiguration sconf =
ResourceFactory.getResourceChangeScannerService().newResourceChangeScannerConfiguration();
sconf.setProperty(drools.resource.scanner.interval, 2);
ResourceFactory.getResourceChangeScannerService().configure(sconf);

KnowledgeAgentFactory.newKnowledgeAgentConfiguration();
kaconf.setProperty(drools.agent.scanDirectories, true);
kaconf.setProperty(drools.agent.scanResources, true);
kaconf.setProperty(drools.agent.newInstance, false);
KnowledgeAgent kagent =
KnowledgeAgentFactory.newKnowledgeAgent(CS, kaconf);
[rules-users] ReteOO, KnowledgeBase and KnowledgeSession relation
Hi, I understand that the ReteOO network is built when a KnowledgeBase is created. Can you please tell me: - if any modifications are made to this network after a session (say StatefulKnowledgeSession) has been created from this KnowledgeBase? - any optimizations made at the session level? (such that time taken to fire rules decreases when certain set of facts are re-inserted and rules re-executed) I could not find any explanation in Drools Expert documentation regarding the above two points. Any pointers explaining the relation between ReteOO, KnowledgeBase and KnowledgeSession will be helpful. Thanks. ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
Re: [rules-users] Drools, slf4j and Eclipse Error on DroolsTest.Java
Figured out the problem. Didn't have Maven installed as a plug-in
correctly. The book I'm using to learn Drools, didn't include that step.

This isn't my code. It's created when a Drools project is created in
Eclipse. I guess that's why this is so frustrating. It's supposed to
demonstrate a very simple Drools program and I can't get it to work.
It's hard to debug someone else's code when you don't know the
language yet.
Code is kSession.insert(message);
Thanks

Re: [rules-users] Drools 6 and Gradle?
Great, thanks Mark! On Tue, Jan 28, 2014 at 4:06 PM, Mark Proctor mproc...@codehaus.org wrote: We require jars that are built to conform to maven standards. But they do not need to be built with maven. That means they do need a pom.properties in there. If gradle does not add that automatically, you should be able to automate that yourself. The pom.properties is a very simple file, that requires 3 key value pairs: *#Generated by Maven **#Wed Nov 18 14:44:09 PST 2009 **version*=*2.2 **groupId*=*javax.el **artifactId*=*el-api * This is necessary for discovery of jars, and versioning of jars within the same JVM. Maven provides a standard for this, so it seemed redundant us creating yet another way to declare this meta data.
