[rules-users] Problem Sharing rules between Rule Flow group

[surya_n2007]

Using 4.0.7 version
Our requirement is we need to share rules between different projects. So we
have grouped the rules into ruleflow group say Group A has 2 rules, GroupB
has 4 rules.Shared GroupB i.e 4 rules in different projects X,Y. Now the
business requirement changed for project Y in GroupB one of the rule doesnt
satisfied.

Solution : Divide the rule flow groupB into GroupB 3 rules ,Group C 1 rule
but we need to test both the projects we dont want to do that .

Please let me know any other solution ? Can a rule be part of different rule
flow groups as shown below.

rule "Rule3"  ruleflow-group "GroupB,Group X"


Cheers
Surya.

[rules-users] How to define an Enumeration when using "Guided Editor" in Eclipse?

[data data]

Hi all

Probably a simple question, but I did not find any hint on this topic.

I am using drools 5.0 in eclipse. There I started to write "business rules"
with the "guided editor". Now I like to introduce some enumeration for some
attributes in my model. In the web based version "Guvnor" is this no big
deal, there you have the option to add new "enumerations". But how can you
achieve the same thing in eclipse? I studied the "package" file syntax, but
there I found no such option (or it is not documented).

Any suggestions and hints?

Many thanks for your help in advance.

regards
Mark

[rules-users] Accessing drools rule file in a jar

[Zhang Jing-A52198]

Hi All,

 

I'm trying to load a pkg file by RuleAgent. I use the following in the
class DroolsRuleProcessor in the package com.example:

 


**

 

String packageFILE = "com.example.rule1.pkg";

URL u = DroolsRuleProcessor.class.getResource(packageFILE);

 

Properties props = new Properties();

props.setProperty("file", u.getFile());

 

RuleAgent ag = RuleAgent.newRuleAgent(props);

 


**

 

 

The package file com.example.rule1.pkg is put under the same java
package as DroolsRuleProcessor (i.e., com.example).

 

The above code works fine when executing locally. However, error occurs
when I try to execute it remotely. I pack the class DroolsRuleProcessor
with the pkg file com.example.rule1.pkg into a jar, put the jar into an
ear file and deploy the ear to a server. The RuleAgent cannot find the
pkg file. I guess the reason might be that RuleAgent uses new File(...)
to access and read the file. However, new File(...) cannot get the file
that is contained a jar.

 

So how can I access the pkg file using RuleAgent in this case?

 

Thanks,

Jing

Almost.

https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-introduction/html_single/index.html#d0e1337

I guess all you need (the engine for now) is in "Drools 5.0 Binaries"

Re: [rules-users] Import Existing DRL in Guvnor never finishes

[Jaroslaw Kijanowski]

Ok, last thing, can you post your repository.xml file? When that is 
fine, then I would blame everything else than Guvnor (connection, 
oracle, ...).
BTW, which version of Oracle?

Re: [rules-users] Relation between Guvnor and Expert in Drools5.0

[Sumant Kumar]

Thank you Jarek.

Where does Drools Expert component fit in. Is Drools EXPERT essentially  
drools-api.jar and drools-core.jar and some other dependent jars ?.

I am not sure why Jboss is not wraping them as component and call it Expert.


thanks
Sumant

Yes (you can have a look at the WEB-INF/lib dir to see what exactly is 
shipped).

Rules are only executed in Guvnor when run in a test scenario.
Rules are exposed by Guvnor in form of compiled packages. You can use 
them in your local Drools application through a Drools Agent [1].

[Steve Ronderos]

The same import worked on a fresh stand-alone version of Guvnor v. 
5.0.1.GA which is using Jackrabbit's built in Derby DB.

Do you see the same issue when using the Jackrabbit's built-in Derby DB?

[rules-users] Problem when deploying Guvnor to glassfish v2.1 cluster

[Zhang Jing-A52198]

Hi All,

 

I have encountered a problem when deploying the latest Guvnor to
glassfish v2.1 cluster.

 

Below is the return:

 

http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";>S
un GlassFish Enterprise Server v2.1 - Error report
HTTP Status 404 - Servlet securityService is not

Any ideas?

 

Thanks,

Jing

[Steve Ronderos]

Sorry, I probably should have included that information.

We are using 5.0.1.GA, Jackrabbit is configured to store the data in an 
Oracle database.  Is there any other information I can provide?

Thanks,

Re: [rules-users] Relation between Guvnor and Expert in Drools5.0

[Sumant Kumar]

Thanks Vijay.

I think I have few more questions. 

1) Does Guvnor include the runtime or Rule engine it self ? I could create rule 
and execute it in Guvnor so does this mean it has Expert included in it.

2) When a end user/app executes/fires a rule where is the rule runtime, is it 
the client JVM or  Guvnor JVM ?
In other words are rules executed in Guvnor that are packaged and made 
available on Guvnor or will they be marshalled
to the client calling the rule and executed in client JVM. 

3) Can you give an example of Drools5.0 deployment pattern. How Guvnor,Expert 
and J2EE app will communicate.

thanks
Sumant

Guvnor àThis can be used to
manage your rules specifically termed as BRMS (Business Rules Management
System). This can really play its part from the “governance”
perspective in your company/enterprise/project. Take a look at this URL 
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-guvnor/html_single/index.html#d0e78
 mainly section 1.1.1 
 
Expert àThis is the actual
runtime/development module for the rule engine. 
 
Take a look at this part (Chapter 3 – Installation and Setup)
of the documentation 
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-introduction/html_single/index.html#d0e1322
 this should help your understanding of various jars and the modules

Hi All,
 
Can you throw some light on Relation
between Guvnor and
 Expert components in Drools5.0.


Guvnor sounds like BRMS so does it
have Rule engine ( or runtime) to execute rules ?. Is Expert module part of
Guvnor ? 


If Guvnor doesn't have rule engine
how does it excute rule when we do QA.


I cannot find Expert module for down
load. Is Rule engine runtime bunch of jars ( Drools-core.jar etc )


thanks
Sumant

[rules-users] Using ArrayList as global in DRL file

[Divya Rajendranath]

Hi,

I am setting an ArrayList as a Global on my drools session by saying ...

StatefulSession drlSession = getRuleManager().getSession();
drlSession.setGlobal("myMailingList", myMailingList);

then in my Drl file, I send the same arrayList as a parameter to the setter
of another object by saying...

package com.test.rules;

import java.util.ArrayList;

global java.util.ArrayList myMailingList;

rule "Test"
salience 100
no-loop true
when
$o:MyObject(some condition)
$d:Destination()
then
$d.setFieldMember(myMailingList)
end

So, based on some condition/field value in MyObject I want to set the
Destination with the arraylist - myMailingList.

Is the way I specify/refer the ArrayList in the then part fine. Because I am
always getting "unable to compile test.drl file - runtime exception".

Could some one please help me with this.

-thnx

Re: [rules-users] matching multiple facts in a rule using a DSL template

[Erik Clairiot]

Okey, I should have spend more time with DSL...
I didn't know it was possible to use a matching pattern either for variable
name :

[when] there is "{name}" as {key}={key} : Variable(id == "{name}")

Sorry for unnecessary posting, have a nice day.
