can't put formula on Guvnor screen
by zeeshan khan
Hi Team !
Earlier I sent this mail to rules-dev(a)lists.jboss.org. Mark
Proctor asked me to mail here so I am mailing here in the hope of reply.
Since yesterday only I started learning Drools with the help of
Google and *JBOSS DROOLS BUSINESS RULES pdf file*. I faced many problems to
understand the concept but now its going smooth. But the problem is
the *version
of PDF file of the book* and the *Govener version*. *Its quite different*.
I request you all to please provide me the latest version of PDF as I am
unable to find on net. The problem I am facing is to put the formula as
given in the screen shot in the book.
I am unable to put the *formula* as described in JBOSS DROOLS
BUSINESS RULES pdf file on page no. 102.....the formula is *salesValue-10
as the box is not capable of taking cahracters. *It is taking only integer.
Thanks in Advance for all the help and material !!!!

Guvnor 5.4 CR1 role based authentication with JBossAS 7
by bhochhi
Hello,
Has anybody successfully set up the role based authentication on Guvnor 5.4
CR1 hosted on Jboss AS7? I tried all possible way I could think of but in
vain. I modified bean.xml(commented <security:IdentityImpl> in whole and
uncommented <security:jaas.JaasAuthenticator> and
<guvnorSecurity:RoleBasedPermissionResolver> ). I also replaced
code="UsersRoles" for <security-domain name="other" cache-type="default">
under <login-module> in standalone.xml. Could anyone please help me how to
configure role-based authentication for guvnor based on properties files? Is
was so obvious on 5.3 or former. But this new 5.4 looks so different.
Thanks

drools.packagebuilder.conf
by Matteo Cusmai
Hi all,
i have developed some custom evaluators, and all worked fine with drools
5.3.
I put the file in object under my home folder.
I would like to pass to 5.4 final, but it doesn't read that file.
Where does it find the file?
Thanks a lot,
Matteo.

need help or any links customizing guvnor
by Abdullah Shaikh
Hi,
I am new to drools & guvnor. I was able to create simple drl file and
run from classpath and from guvnor too using url.
I saw that we can create rules in guvnor but I want to know if we can
provide UI for creating rules ? I am not sure but I think what I want
is guided editor ?
Thanks,
Abdullah

Guvnor test case with fact with Object fields
by mpgong
Hello,
I have a fact that has is also my entity model and it has a field that is a
class called state which holds previous and current state values (enum).
So i have a condition that gets the state and gets the two values to check.
The issue i'm running into is with creating a test case in guvnor, is it
possible to create a test case with a field that is an object like this?
Guvnor recognizes that i have a field called state but it doesn't realize
that it is a class so it doesn't look like i would be able to test any rules
the uses state as a condition check.
Thanks

command line to import repository
by halljme
we have many environments and require the ability to refresh these
environments weekly. this would be much easier to perform via a script/cron
then requiring to perform via manually. Has any thought been put into
creating such or does the ability exist but is just undocumented?
I read a post back on Dec 1, 2009 requesting such ability and as of then,
there was not a way of performing this. I cannot imagine there has not been
any thought or development to perform such a menial task via command line to
enable scripted processes.
If the ability exist via GUI then there has to be some command(s) that exist
to perform an import via command line. At least the logic exists, so the
command should not be to difficult to develop.
respectfully, jme

DRL to XML transformation
by Anirban Bandyopadhyay
Hi,
We have a set of rule files in DRL format. We couldn't find a way (tool) of importing them into Guvnor as BRL file so that we can edit using the designer.
We ended up using the DrlParser and XmlDumper to transform them from DRL to BRL. It produces the XML and when we add it to the repository using WebDav, Guvnor lists the files under Business Rule which is perfect. BUT when I try to open it, it throws the following error:

I am able to re-produce the same error when I try to convert the BRL to DRL using BRDRLPersistence and BRXMLPersistence marshalling and unmarshalling. I checked that the field 'rule-attribute' is indeed not present in org.drools.brms.client.modeldriven.brl.RuleModel. when I look at the example brl file from the sample mortgage, they don't have 'rule-attribute', and it's not only that specific node, the whole set of node names are different.

Am I doing something wrong? Is there a better way of converting the DRLs to BRLs?
Thanks in advance!
