[rules-users] 5.6.0 Unable to authenticate for rest api: null

[anjana.ackroyd]

I had perm gen issues on 5.5 so I upgraded to 5.6 now I get authentication
denied

In my ChangeSet.xml 

If I access my

with no userid /password and admin/admin it works 
I am not sure why null is being picked up?

I am not sure why its picking up null?


similar changeset worked great on 5.5.0


Also tried commenting out the following lines in beans.xml with no luck.




also commented out 
xmlns:security="urn:java:org.jboss.seam.security"
xmlns:guvnorSecurity="urn:java:org.drools.guvnor.server.security"




Downloaded the guvnor war from 
http://downloads.jboss.org/drools/release/5.6.0.Final/

Re: [rules-users] permgen error for simple rule stress test

[anjana.ackroyd]

Mark,

I did some more analysis  and I tracked it down to Guvnor my app connects to 
running out of memory before the test starts failing.Once I restart guvnor
and redo my tests I get good response time and it eventually starts to slow
down then throw 500 errors.

I see a whole bunch of logs for Creating RulesRepository with default
username.  like before it throws out of memory

[rules-users] permgen error for simple rule stress test

[anjana.ackroyd]

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"

Here is 

I have a simple rule file deployed on guvnor on my abc with JVM_OPTS on the

Re: [rules-users] How to push changes to cloned repo on Kie-Workbench

[anjana.ackroyd]

 I was under the impression that under Authoring->Administration->
Repositories->Clone Repository is actually making a local copy for me to put
my jar files into?
I cloned my repository

GIT URL I used
ssh://gitolite@vlslcdapp01:22/
com.enterprise.service/service-rules-dsl
After I wrote my DRL etc I went Tools->Project Explorer -> Build and Deploy
Then Project Settings -> Add From repository and added the jar I just
created

When I look at Administration I see my repo listed with my package and drl
files in it.

Now if I dont get to push these changes to the service-rules-dsl repo then
how will my Java code access the drl file from it?

[rules-users] How to push changes to cloned repo on Kie-Workbench

[anjana.ackroyd]

I was able to do all my steps successfully on the work bench , Cloned my
repository, added a new project, package,drl file, build and deployed it. 

I see wb created the repositories on my local machine which is good but I
dont see a way to push those changes to my cloned reposity 

Git Push?
I am not even sure what branch of the cloned repository the work bench is
using 


I noticed on this URL below there is recommendation to use the
./kie-config-cli.sh script to push changes
http://docs.jboss.org/drools/release/6.0.0.Final/drools-docs/html/wb.Workbench.html

I downloaded the zip file from 
https://github.com/droolsjbpm/kie-wb-distributions/tree/6.0.x

Ran the script from  \kie-config-cli\src\main\dist but I get a error message

I was hoping there would be a way to push my changes from the Workbench UI
itself.

Re: [rules-users] Kie Work Bench missing repositories menu option

[anjana.ackroyd]

Thanks adding port 22 helped!

GIT URL I used 
ssh://gitolite@vlslcdapp01:22/com.enterprise.service/service-rules-dsl

Re: [rules-users] Kie Work Bench missing repositories menu option

[anjana.ackroyd]

Sorry for not giving the exact error . 

Here is what I see on the console as a pop-up . Although no logs get written
to server.log
Can't clone repository. java.lang.RuntimeException:Exception caught during
execution of fetch command



Here is how I know my GIT URL 
$* git config --get remote.origin.url*
gitolite@vlslcdapp01:com.enterprise.service/service-rules-dsl

In the console -> Clone Repository -> When I put in 
* Git URL
git://gitolite@vlslcdapp01:com.enterprise.service/service-rules-dsl

I get 
Can't clone repository. java.lang.RuntimeException:Exception caught during
execution of fetch command


I tried it with http:// and also ssh:// get the same error . 

Here are the formats for GIT URL 
The following syntaxes may be used with them:

ssh://[user@]host.xz[:port]/path/to/repo.git/

git://host.xz[:port]/path/to/repo.git/

http[s]://host.xz[:port]/path/to/repo.git/

ftp[s]://host.xz[:port]/path/to/repo.git/

rsync://host.xz/path/to/repo.git/

But When I remove gitolite@vlslcdapp01 and add my URL like 
* Git URL
git://com.enterprise.service/service-rules-dsl

or ssh://com.enterprise.service/service-rules-dsl
 it starts cloning, but is in loading mode for ever I assuming thats because
its not the right URL 

The servers are on the same network so no proxy involved. I said it doesnt
like it because the error returns right when I hit Clone button no logs are
being written which is not helpful

Re: [rules-users] Kie Work Bench missing repositories menu option

[anjana.ackroyd]

Sorry one last question hopefully 

To clone a repository on my machine I run 

git clone gitolite@vlslcdapp01:com.enterprise.service/service-rules-dsl


In the Kie-wb I am trying to clone a repository , if I put the URL as 

git://gitolite@vlslcdapp01:com.enterprise.service/service-rules-dsl it
doesnt like it

I cant just put git://com.enterprise.service/service-rules-dsl because my
repo is hosted on a remote machine

Re: [rules-users] Kie Work Bench missing repositories menu option

[anjana.ackroyd]

Yay! I found the conflicting process using that port and now its all golden .
I see all the menu options. 
Although it would be nice to have it working on tomcat as well because thats
the JVM we use enterprise wide. But for now I am going to go ahead and play
with the work bench in jboss!


Thanks a lot !

[rules-users] Kie Work Bench missing repositories menu option

[anjana.ackroyd]

I deployed
kie-drools-wb-distribution-wars-6.0.0-20131207.033517-672-tomcat7.0.war to
my tomcat. I am trying to point it to the repository I have by using the
steps listed
http://docs.jboss.org/jbpm/v6.0/userguide/wb.Workbench.html#wb.QuickStartAddRepository

But under Administration all I see is File Explorer

Re: [rules-users] How to insert values into drl

[anjana.ackroyd]

Thanks. Now when I do a get on Message I get a null value. I was under the
assumption that the drl n.setMessage is setting the value for message 

  FactType factType =
runner.buildFactType("org.drools.test","NumberCompare") ; 
Object nc = factType.newInstance(); 
factType.set( nc, "numberone",Integer.valueOf( 42 )); 
factType.set( nc, "numbertwo", Integer.valueOf( 42 ) ); 
kieSession.insert(nc); 
runner.fireAllRules(); 
System.out.println(factType.get(nc,"message"));--> is
null 




In the DRL 


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

[rules-users] How to insert values into drl

[anjana.ackroyd]

Hi,
I am new to drools and trying to figure out how to get this simple example
working.
I have intellij IDE . 
I am trying to compare two numbers using drools 6.x and dont know how to
insert numberone and numbertwo after I get my drl file into my file system

Here is my code

RuleRunner.java
package com.cambiahealth.enterprise.service.droolsrule;

import org.kie.api.KieServices;
import org.kie.api.builder.KieBuilder;
import org.kie.api.builder.KieFileSystem;
import org.kie.api.builder.KieRepository;
import org.kie.api.builder.Message.Level;
import org.kie.api.io.KieResources;
import org.kie.api.io.Resource;
import org.kie.api.runtime.KieContainer;
import org.kie.api.runtime.KieSession;

public class RuleRunner
{
private KieServices kieServices;
private KieContainer kieContainer;
private KieSession kieSession;
private KieResources kieResources;
private KieFileSystem kieFileSystem;
private KieRepository kieRepository;

public RuleRunner()
{
this.kieServices = KieServices.Factory.get();
this.kieResources = kieServices.getResources();
this.kieFileSystem = kieServices.newKieFileSystem();
this.kieRepository = kieServices.getRepository();
}


public void addRuleFile(String packagename, String rulefile)
{
Resource resource = kieResources.newClassPathResource(rulefile);

packagename = packagename.replace(".","/");

String resourcepath =
"src/main/resources/"+packagename+"/"+rulefile;

kieFileSystem.write(resourcepath, resource);
}

public KieSession buildKnowledgeSession()
{
KieBuilder kb = kieServices.newKieBuilder(kieFileSystem);

kb.buildAll();

if (kb.getResults().hasMessages(Level.ERROR))
{
throw new RuntimeException("Build Errors:\n" +
kb.getResults().toString());
}

kieContainer =
kieServices.newKieContainer(kieRepository.getDefaultReleaseId());

kieSession = this.kieContainer.newKieSession();

return kieSession;
}

public KieSession fireAllRules()
{
kieSession.fireAllRules();

return kieSession;
}

public void dispose()
{
this.kieSession.dispose();
}
}






My numbercompare.drl 


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









My DroolsService.java where I want to pass in values 1 and 2 to the drl file


runner.addRuleFile("drools", "compareNumberRule.drl");

   KieSession kieSession = runner.buildKnowledgeSession();
  //How do I pass 1 as numberone and 2 as numbertwo values ? before
firerules
runner.fireAllRules();
runner.dispose();
return number.getMessage();  //To change body of implemented methods
use File | Settings | File Templates.
}
}
