This doesn't tell me much. Maybe there's more in the log?

-> "Truncated. see log file for complete stacktrace"

This might help as well.

One more thought - you have provided the Oracle driver to your app 
server, right?

Re: [rules-users] how to move a repository from derby database to Oracle Database

After the repo export, you need to delete the whole repository directory 
which includes:
repository
version
workspaces

and you have to clear the schema in Oracle you want to use - Guvnor will 
prepare the DB during deployment when accessing a fresh DB.

When you login, you should be asked to install a sample repo - simply 
press "No, thanks" and then import your repo from xml.

Re: [rules-users] how to move a repository from derby database to Oracle Database

What you have provided is just the driver class, but yeah, this is the 
right one.
Moreover I would also consider to change the FileSystem to use 
"org.apache.jackrabbit.core.fs.db.OracleFileSystem" instead of the local 
file system.
But this is strictly Jackrabbit related stuff and you would need to have 
a look at their docs for further details.

Re: [rules-users] how to move a repository from derby database to Oracle Database

Before you switch to Oracle, go to the Administration tab and export 
your repository.
Then configure your repository.xml file to point to Oracle, remove the 
repository directory (most probably in jboss-as/bin) and start your 
server. Then go to the admin tab and import your repo (first you need to 
unzip the xml file).

Cheers,
  Jarek

Re: [rules-users] Integration issue : Guvnor with Openldap

2010-04-21 Thread Jaroslaw Kijanowski

Try this one:




ldaps://localhost:16636
ssl
cn=DirManager,dc=kijanowski,dc=eu
admin123
ou=People,o=guvnor,dc=kijanowski,dc=eu
(uid={0})
ou=Roles,o=guvnor,dc=kijanowski,dc=eu
(member={1})
cn
-1
ONELEVEL_SCOPE




When you have followed the tutorial, then you have setup ssl, so please 
keep in mind to use ldaps instead of ldap in the connection url. Change 
also the port from the default one, 389, to 16636.

And yes, the tutorial has a bug showing the login-config.xml file, since 
it has been copied over without the corresponding xml attributes...

You need to put that jar into

It will be copied over to the bin directory automatically and then

This is not a valid package, should be
"package/CorporateAction/LATEST"
instead of
"package*s*/CorporateAction/"

'LATEST' is the name of your latest build, it could be also a snapshot.

Looks like it is related to this open jira:

 Still trying to get this to work.
 I have managed to create from a default (new) guvnor setup.

 Steps I do..
 1. Create fresh guvnor
 2. In eclipse create  Message.java file in package com.sample, and
>>> create
 a jar file
 3. In guvnor import the model for the Message.jar file
 4. In guvnor create a category
 5. Create an import statement for  import com.sample.Message
 6. Create a simple technical rule,  something like   when, Message(),
 then, System.out.println(".");
 7. Build the pkg
 8. download the pkg

 use the code from previous post to load the pkg...
 it works fine..

 now, goto guvnor advanced view and change the Configuration from:
 import com.sample.Message

 to:

 import com.sample.Message;

 declare Message
   @role( event )
 end


 build the pkg,
 download the pkg,
 run the test program...

 I get:

This was broken in 5.0.1, but works fine in trunk.

Yes, just use the "drools.resource.urlcache" system property.

Re: [rules-users] Implementaion of Rule Flow in Guvnor

2009-11-03 Thread Jaroslaw Kijanowski

Hi Ambika,
  your rules in the first rule flow group "MasterHud" set a new value on 
a fact's field.
Then you expect that your rules in the second rule flow group fire.
The rule engine has no idea that some facts' fields changed until you 
let the engine know via update();

Open your MasterHud decision table and edit the action column (check the 
'Update engine with changes:' check box), build the package and enjoy.

Cheers,
  Jarek

Re: [rules-users] how to use xml file instead of java object ?

2009-08-20 Thread Jaroslaw Kijanowski

Hi,
  have a look at the dsl:

http://anonsvn.jboss.org/repos/labs/labs/jbossesb/tags/JBESB_4_6/product/services/jbrules/src/main/resources/XPathLanguage.dsl

This rule expects an object of type org.jboss.soa.esb.message.Message 
which contains the XML in its body.

Also note that a lot of stuff is going on behind the scenes:
http://anonsvn.jboss.org/repos/labs/labs/jbossesb/tags/JBESB_4_6/product/services/jbrules/src/main/java/org/jboss/internal/soa/esb/services/routing/cbr/DslHelper.java

Drools Pipeline might be helpful in inserting XML data into sessions.

Almost.

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

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?

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].

One option is the Drools Agent.

Re: [rules-users] error in writing test scenarios

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

It might be also useful to see your rules.

I don't know where/how Jackrabbit persists the data in a DB. Moreover 
I'm not sure if you should rely on this data (format, location where 
it's stored). But that's just my opinion ;)

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

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

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.

Haven't heard of anybody replacing Jackrabbit with another JCR 
implementation before - share your experience when you try :)

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

also have to provide (upload) a model used in your DT.

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

I see, and I guess, it's not possible for those users to update rules in
OpenOffice/Excel and upload them to Guvnor? See my answers below, but
they won't satisfy you ;)

I have following questions :
- How do have have to use an eval condition? Whitin the eval I
have to call a piece of java code with a number of parameters
coming from the fact model.

simply write a snippet in a cell

>>> In Govnor?

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

- How can I prioritize rules?

use the PRIORITY keyword

>>> In Govnor?

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).

Details are in the documentation:

https://hudson.jboss.org/hudson/job/drools/lastSuccessfulBuild/artifact/trunk/target/docs/drools-expert/html_single/index.html#d0e5762

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.

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).

call a piece of java code with a number of parameters coming from the 
fact model.


simply write a snippet in a cell


- How can I prioritize rules?


use the PRIORITY keyword


- How to use global variables?


use the Variables keyword

Details are in the documentation:

Re: [rules-users] variable binding without condition in Decision table

It should work without creating a dummy constraint, try this:

CONDITION

$serviceContract:CreditServiceContract()

I have a decision table where I need to bind a variable to use in the 
action.  The problem is that the binding does not happen unless I apply 
a condition.  What I want in the resulting rule is this:


$serviceContract: CreditServiceContract ( )

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


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




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

Thanks

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

I dug into the code and came across "categoryReference" in

If any of you could share examples where you have done custom

Re: [rules-users] ResourceChangeNotifier and subscribeResourceChangeListener()

2009-06-08 Thread Jaroslaw Kijanowski


Hi,
 maybe this helps:
http://downloads.jboss.com/drools/docs/5.0.1.26597.FINAL/drools-expert/html_single/index.html#d0e1123

"Resource scanning is not on by default, it's a service and must be 
started, and the same is true for notification. Both can be done via the 
ResourceFactory."


Have a look at "Example 3.19. Starting the Scanning and Notification 
Services"

Re: [rules-users] Guvnor Package Builds & The EGT w/ver. 5.0.0 CR1

Hi,
 same happens if you update your rule in Guvnor. The rule agent won't pick
up the changes; you have to rebuild the whole package. Same for EGT. So it
looks fine to me what you're seeing.

Re: [rules-users] Guvnor - assigning roles to users

2009-05-05 Thread Jaroslaw Kijanowski

Hi,
 here's my understanding:
Roles are only then taken from JAAS, if you *disable* fine grained
authorization (set enable-role-based-authorization to false).
There are two roles that are available if you use JAAS: admin and non-admin.

So you can use JAAS for *authentication*, no problem. You can also use JAAS
for *authorization*, but then you have only two roles available. If you want
to use *Guvnor specific roles* for *authorization*, then you need to enable
fine grained authorization and set up all roles in Guvnor. Before you do
this you will have to create some user that is an administrator in Guvnor
using the GUI. Otherwise enabling fine grained authorization will make it
impossible to login as an administrator - JAAS will let you in, but Guvnor
will not let you do anything.

Re: [rules-users] One question about Database interface

2008-07-08 Thread Jaroslaw Kijanowski


Mapping is the job of Hibernate, not Drools ;)

To be able to manage data in/from a database (persist, read,...) you 
need to configure Hibernate and one of these config steps is to provide 
the mapping.

Hi,

Thanks a lot! The information is really helpful.

One more question is that: I have to create the mapping between

Hi,

Jaroslaw Kijanowski's article looks like a really good starting point
for you!

Hibernate provide Entity Manager and Annotations extensions if you want
to go the JPA route.

>From a Drool's perspective you need only concern yourself with "from"
which is documented as:-

6.5.2.8. From

The from Conditional Element allows users to specify a source for
patterns to reason over. This allows the engine to reason over data not
in the Working Memory. This could be a sub-field on a bound variable or
the results of a method call. It is a powerful construction that allows
out of the box integration with other application components and
frameworks. One common example is the integration with data retrieved
on-demand from databases using hibernate named queries.

For information on the rest of Jaroslaw's example, you will need to read
up on Hibernate.

Subject: [rules-users] One question about Database interface

Hi all,

Is there some convinent database interface implemented in Drools
(store and retrieve data from DBMS, such as mysql) ?

I checked the manual, and found no such information. So I am assuming
that I will have to use JDBC. Is it right?

Thanks,
Senlin Liang

Re: [rules-users] question about updating main memory

2008-07-07 Thread Jaroslaw Kijanowski

What I'm missing is an import statement in your drl file (import 
tests.Test.ClassP;).
Everything else looks correct and should give the expected results 
(ResultSize = 5).


Cheers,
 Jarek

Hi all,

I am trying to insert some object, querying them and the retract them.
My question, when I query the inserted objects using defined "query",
it return 0 objects. But when I iterate over all objects in WM, the
objects are returned.

Any information is appreciated!

Re: [rules-users] logging

Good point! Using an AgendaEventListener instead of logging every rule 
in the RHS is the way to go.

May be you could store the names of every fired rule in a global by putting
drools.getRule().getName() into a list on the RHS.
Then you could get all rules in your package ( pkg.getRules() ) into another
list and "diff" both collections (another_list.removeAll(list) ).

Hi,
How can i log that where a rule is executed or not for supplied data? If
the
rule fires, in 'then' section i can have a log statement.
How can i log that the rule is not executed??

I need to log in both scenarios.

Thanks,
Ravi Thalupula


Hi Ravi,

have you looked at the logging facilities included in Drools,
especially AgendaEventListener? That way you wouldn't have to manually
log activations in the RHS of every rule. Diffing the the names of
available rules versus those collected by the logging seems to me the
most straightforward solution, too.

Best regards
Marcus

Re: [rules-users] Re: access to in working memory generated objects


Hi,
 it may also help to have a look at the PetStore example.

Alexander Claus wrote:
I want to use rules which shall generate as a consequence a new java 
object.

The GUI of my application shall display the new generated objekt.
but how can the GUI of my application get informed by the rule engine 
that
it has generated a new object (Warning)? And how the GUI or any other 
java

component can access this new generated object from outside?


Have a look at org.drools.event.WorkingMemoryEventListener.
I think you find yourself how to use it.

Best regards.

Re: [rules-users] Running Drools 4 examples

Ron Kneusel wrote:

Greetings!

I am attempting to run the HelloWorld example for Drools 4. I have Eclipse 3.3 setup on Windows with the Drools plugin. I have created a project with the Drools examples and added all the Drools .jar files to the project. Everything compiles. When I initially ran HelloWorldExample.java it appeared that it could not find the HelloWorld.drl file.

Try to add src/main/rules to your source folders on build path.

> So, I moved that file into the same directory as
HelloWorldExample.java and ran again. This time I am getting an error
that the JDT compiler is not found even though it appears that there are
JDT jar files in the Eclipse plugins.

Try to add org.eclipse.jdt.core_xxx as an external jar to your project's
libraries.

BTW, both steps are performed by the drools plug-in when you create a
Drools Project.

I also attempted to run this example under Linux from the command line. In
this case I placed all the Drools .jar files into the JRE ext folder and
changed the source code to use the Janino compiler by adding:

It should be sufficient to have drools-compiler.jar, drools-core.jar,
antlr-runtime.jar, mvel.jar and janino.jar in your classpath.

// Set up for the Janino compiler, not Eclipse
System.setProperty("drools.dialect.java.compiler", "JANINO");
PackageBuilderConfiguration cfg = new PackageBuilderConfiguration();
JavaDialectConfiguration javaConf =
(JavaDialectConfiguration)cfg.getDialectConfiguration("java");

This version compiles with javac and runs with java -cp . HelloWorldExample but
gives me an error within the compiler while compiling the .drl file:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String
index out of range: -1

at
org.drools.compiler.PackageBuilder.addPackageFromDrl(PackageBuilder.java:167)
at HelloWorldExample.main(HelloWorldExample.java:39)

It is dying on this line:

builder.addPackageFromDrl( source );

My version of HelloWorldExample.java the same as the given example except for
the addition of the lines above for Janino. My ultimate goal is to run this
all under Linux, I am not an Eclipse user.

Any help getting this working would be greatly appreciated!

Ron
