Hi,
  please provide some more details. Maybe a screen shot of your test

It might be also useful to see your rules.

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

Hi,

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.

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

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.

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].

3) Can you give an example of Drools5.0 deployment pattern. How
Guvnor,Expert and J2EE app will communicate.
One option is the Drools Agent.

Guvnor à This 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

Guvnor sounds like BRMS so does it have Rule engine ( or runtime) to

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

Ok, last thing, can you post your repository.xml file? When that is

BTW, which version of Oracle?

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

You might be also interested in the latest bits from trunk:

   Hi,

   By default Drools Guvnor supports Embedded derby, but in OFBiz i am

   the default embedded derby to MySql using repository.xml file by the
   following code.
  
   PersistenceManager
   
 class=org.apache.jackrabbit.core.persistence.bundle.MySqlPersistenceManager
  
 
  
 param name=url

 param name=schema value=mysql/
 param name=schemaObjectPrefix value=${wsp.name}_/
   /PersistenceManager
  
   Using this I successfully integrated Drools guvnor with same database as
   I am using for OFBiz(MySql).
  
   Now I have created a new user in Drools guvnor to create permission for
   that user, but I am not able to see
   where that username is stored in the database and in which entity or
   table of MySql.
  
   Also if i want to use the users available in OFBiz MySql database
entity say 'Userlogin' where i am storing all the list of userlogins,
   how can
   I retrieve the same and use this table data in drools Guvnor.
 
 This can be done via JAAS - you just need to configure it to use a
 particular table in mysql for retrieving user logins/passwords.
 Keep in mind that this is just for authentication (to login).
 Here's a list of all available login modules:
 http://www.jboss.org/community/wiki/LoginModule
 http://www.jboss.org/community/wiki/DatabaseServerLoginModule
 
   Also when
   I make a new user in Drools Govnor through
   administrator, my data of new user should go to  table 'UserLogin'.
 
 AFAICT that's not possible and you need to synch your Guvnor user list
 with the OFBiz user list by yourself.

Yes, you are in the right track, and I understand this is a bit
 confusing at first. One more reason for people to go to the October
 Rules Fest 2009 where I will give a presentation on all the ways to
 extend the engine to solve specific problems. It will be interesting
 I hope (last year was awesome) and even Charles Forgy will be there
 doing a presentation on Parallel Rete. :)
 
 Meanwhile I will write a tutorial on this, but just to help you
 there, your approach is correct, except that you don't need to setup
 the option for each operator. It works like this:
 
 * One EvaluatorDefinition class implements support to one or more
 evaluators, defined by the method public String[] getEvaluatorIds().
 
 * All you need to do, then, is wire you class once and the engine
 will pick-up all the IDs supported by that class. When you have your
 class wired, you give it a unique string identifier, so that if you
 ever need to replace it, or remove it, you will use that id.
 Sometimes we use the operator as the ID, but usually it is something
 that reminds you of the kind of evaluators that class define. For
 instance, drools registers the ComparableEvaluatorsDefinition in
 this way:
 
 drools.evaluator.comparable =
 org.drools.base.evaluators.ComparableEvaluatorsDefinition
 
   So in this case, comparable is the identifier. Finally, from my
 previous e-mail you will see that the reason that the eclipse IDE is
 still giving you errors is that you are using the API to configure
 the evaluators. Just move the configuration to the configuration
 file and the IDE will pick it up.

 So my question is there a way i can use OFbiz entity engine persistence

Jackrabbit is a JCR, OFBiz isn't, right? You should be able to replace 
Jackrabbit with any JCR implementation. IMO OFBiz is not an option.

 Is it feasible to do this and if possible how much effort is needed?

Haven't heard of anybody replacing Jackrabbit with another JCR

Re: [rules-users] Drools Govnor DB configuration

Hi,

 Hi,
 I am using Apache OFBiz and had successfully integrated Drools Guvnor 
 war file with OFBiz.
 By default Drools Guvnor supports Embedded derby, but in OFBiz i am 
 using MYSql , so i changed
 the default embedded derby to MySql using repository.xml file by the 
 following code.
 
 PersistenceManager 
 class=org.apache.jackrabbit.core.persistence.bundle.MySqlPersistenceManager
  
 
   param name=url 
 value=jdbc:mysql://localhost:3306/drools/
   param name=user value=root /
   param name=password value=Newuser123 /
   param name=schema value=mysql/
   param name=schemaObjectPrefix value=${wsp.name}_/
 /PersistenceManager
 
 Using this I successfully integrated Drools guvnor with same database as 
 I am using for OFBiz(MySql).
 
 Now I have created a new user in Drools guvnor to create permission for 
 that user, but I am not able to see
 where that username is stored in the database and in which entity or 
 table of MySql.
 
 Also if i want to use the users available in OFBiz MySql database 
  entity say 'Userlogin' where i am storing all the list of userlogins, 
 how can
 I retrieve the same and use this table data in drools Guvnor.

This can be done via JAAS - you just need to configure it to use a 
particular table in mysql for retrieving user logins/passwords.
Keep in mind that this is just for authentication (to login).
Here's a list of all available login modules:
http://www.jboss.org/community/wiki/LoginModule
http://www.jboss.org/community/wiki/DatabaseServerLoginModule

 Also when 
 I make a new user in Drools Govnor through
 administrator, my data of new user should go to  table 'UserLogin'.

AFAICT that's not possible and you need to synch your Guvnor user list 
with the OFBiz user list by yourself.

Cheers,

 Please help me how this can be achieved in Drools Guvnor.

Re: [rules-users] role based authentication in tomcat


Hi,
 so far you have just created a name for your jaas configuration, 
called brms. If you would use JBoss AS, you would need to create a 
jaas config in server/default/conf/login-config.xml. Details are here:

http://blog.athico.com/2008/08/tuning-guvnor.html

Keep in mind that you use JAAS only for *authentication*. Authorization 
is set in Guvnor (Administration tab).
Before you start, you also need to create an account in Guvnor that has 
admin rights, otherwise you will be able to login (authentication via 
JAAS) but nothing more (authorization via Guvnor).


Cheers,
 Jarek

Re: [rules-users] Guvnor deployment pattern


Hi,

rviswanathan wrote:

Hi,
I would like to understand the deployment pattern supported by Guvnor. 
Everytime when I add the rules or model objects on Guvnor those files are
checked in on SVN repository.  


1.) Where exactly those files are stored?


Out of the box it's stored in Jackrabbit's built in Derby data base (in 
files).


2.) In case of SVN, Which SVN repository (What’s the URL)? 


It's a JCR repository, not SVN.


3.) Is it possible to define the list of rules on Guvnor  use those rules
across the application wherever drools-guvnor.war is deployed?  If so, what
all steps need to be followed?


Yes, all rules are stored in a repository, by default located in the 
JBoss AS bin directory.
So you can either copy the repository dir and repository.xml file to 
another JBoss instance, or you can export your data (Administration tab) 
and import it again in the new Guvnor.

Why do you need to convert them into web based DTs? What's the

I want to convert my excel decision table to enable busines users to

OpenOffice/Excel and upload them to Guvnor? See my answers below, but
they won't satisfy you ;)

I have following questions :

have to call a piece of java code with a number of parameters

AFAICT that's not possible in web based DTs. Would need to be done as
part of some 'free form drl' I guess...

Yep, in Guvnor, this attribute is called salience (available from the
options section).

- How to use global variables?

use the Variables keyword

In Govnor?

Globals are still available, but the use of them is quite limited (you
can't add results to a java.util.List for example).

$serviceContract: CreditServiceContract ( )

This is what I want but does not work.  The binding does not happen so

This works but I hate to add an arbitrary condition just to accomplish a

I'm sure I am just missing something.  Can someone point that out?

Re: [rules-users] Creating custom selectors using the category property for deploying certain rules in guvnor

2009-07-06 Thread Jaroslaw Kijanowski


Have a look at this class:
drools-repository/src/test/java/org/drools/repository/AssetItemTest.java

The doc in the selectors.properties file is talking about properties of 
AssetItem - however, don't take it literally - a rule uses a getter, 
hence it's sufficient to have such a method in the AssetItem class 
instead of a regular field. So if you see a getStateDescription method 
you can use stateDescription - that's at least my understanding.


So looking at AssetItem and VersionableItem I see following candidates 
for a selector:

name
createdDate
versionNumber
creator
lastContributor
checkinComment
categories (java.util.List)
categorySummary (space separated string of categories)
precedingVersion
format
stateDescription
lastModified
dateEffective
dateExpired
description
succeedingVersion
content
title
disabled

Let's get back to your original question (I've answered it already in jira):
Try this out:
package org.drools.guvnor.server.selector

import org.drools.repository.AssetItem
import org.drools.repository.CategoryItem
import org.drools.guvnor.server.selector.Allow


rule 'select all rules assigned to myCategory'
dialect 'mvel'
when
  ai : AssetItem()
  CategoryItem(name == myCategory) from ai.categories
then
  insert (new Allow( ) );
end


Cheers,
 Jarek

Hi Jaroslaw,


I voted for https://jira.jboss.org/jira/browse/GUVNOR-109
and added the following comment:

+1 for this request.
The ability for users to choose among which selectors are available is 
awesome.


Here's an extra requirement that I am bringing forward, not sure what 
the complexity on this is:

The list will be populated based on user permissions of some kind.
ie, not all the users can deploy production rules, but all can deploy QA 
rules, for example.

 

I have also created https://jira.jboss.org/jira/browse/GUVNOR-392 for 
including categories as a field for filtering.


Regarding your tip on using the 'status' field, I was planning for the 
workaround, though it messes with the actual value of this field which i 
was planning to use.
Based on our environment, we might actually use the author field as 
currently there will not be many authors and we are tracking 
functionality by using categories anyways.


I have the following questions that are still unanswered:
1) I am trying to figure out where the code for statusDescription is?
2) You have suggested 'categorySummary'  - was wondering where these 
fields are configured.
3) the minimal documentation in selectors.properties tells only about 
the fields status, lastModified date and author, and ends with etc. 
Could one of the devs kindly post ALL the fields that could be used?

Prem

Hello everyone,

I am trying to create a custom selector, based on certain
properties such as categories (primary property) and others
such as status and author.

from the examples in selectors.properties, I could not see a way
to create using categories. In that file, some of the field
described are statusDescription, lastModified, creator, etc
I was trying to find the complete list of all fields that could
be used to filter the rules.

I dug into the code and came across categoryReference in
VersionableItem.java. Is this the variable that stores the category?
Since a rule can have multiple categories, how does this pan
out? Is this a Collection?

Also, where does the string statusDescription get tied in to
the status of a rule? This one throws me off, since it is a
valid field, but I cannot understand how it is being set.

If any of you could share examples where you have done custom
selectors either in java or in drl, that would be awesome.
