Drools-Guvnor doubt regarding cosuming a previous rule generated.
by Pardeep Ruhil
Hi,
I have doubt regarding rules made in drools-guvnor.
>From the documentation I have read that, I cannot have two rules of the same name.
But is there a facility available like I have rule created with date-expires=30-July-2011, and after some time I
changed the same rule and specifies new date for expire as date-expires=20-Oct-2010.
Now can I call the previously created rule programmatically i.e. of 30-July-2011
Or can I call the previous version of the rule programmatically, created in drools-guvnor.
Please help me in this.
Thanks & Regards

Problem in executing Rule in Drools Guvnor for date-effective attribute
by Pardeep Ruhil
Hi,
I have created a rule in drools-guvnor and I have given date-effective parameters in that.
My rule looks like when I click on view source as :
1.
|
rule "ProfTaxPradeep"
2.
|
date-effective "28-July-2010 "
3.
|
dialect "mvel"
4.
|
when
5.
|
empInfo : EmplInfo( state == "KA" )
6.
|
profTaxResult : ProfTaxResultPradeep( )
7.
|
then
8.
|
profTaxResult.setProfTaxResult( profTaxKA_pradeep(empInfo.basicSal,"10000:15000:999999999", "00:150:200") );
9.
|
end
Now when I created a test scenario in Drools-Guvnor, it is not running successfully.
I have given the simlulated time as Friday, July 30, 2010 12:00:00 AM
But it is not running successfully.
Without using the date-effective attribute my test scenario executes properly.
Please tell me if I am doing anything wrong in this.
Thanks & Regards
Pradeep Ruhil

Hi,
Which version of drools are you using? Make sure you are using the same
version in guvnor and in your application.
Best,

Guvnor 5 on Tomcat 5.x?
by Hendrik Beck
Hey guys,
just a quick question: can anyone confirm that Guvnor 5 is running or _not_
running on Tomcat 5.x. I have tried it some time ago without success and now
I'm hearing here that my co-workers tried again without success. Does anyone
have experience with that and can give a quick info?
Thanks a lot and best regards

No variable subsittution in templates under UNIX
by David Green
I have some template driven rules code that runs fine on my PC. When I move
the code to a workstation, the templates generated do not have the templates
parameters replaced with the text of the corresponding variables. While
this seems like it could be a JAR issue, no exceptions are reported. Might
there be a property I need to set? Below is an example of my results on the
workstation. Thanks!
rule "rules for reject 0"
lock-on-active
when
$m : MyReject(
in (
then
end

Dynamic attribute in Guvnor
by bbarani
Hi,
We have a scenario as below,
Here is what we want to achieve. Let’s say we want to have following rule:
When AssetType = DSTR Then Decision = Granted.
I can have AssetType as static class or attribute in the model. But this may
limit our ability to handle new information. Let’s say now I have rule to
restrict access to a specific metadata asset like:
When AssetID = 8-XXX-1234 and Group<>’HR’ then Decision = Denied.
If we don’t have AssetID, then no one can define that rule until we change
the code. What we really want is if Drools can do something like this:
When DynamicAttribute(“AssetID”) = 8-xxx-1234and Group<>’HR’ then Decision =
Denied.
Any one has implemented anything similar to this before??
Thanks,
BB

Re: [rules-users] Uploading models to Guvnor
by Zhuk, Yefim
>"Unable to validate package configuration"
This message after uploading a jar file in Guvnor often means that the classes in the jar depend on some library that is not included.
It's hard to say precisely without the jar, but check this possibility (check imports)
I'd recommend to upload a jar with just one-two classes with no extra dependences.
Hope this helps,
Jeff

Hi Mark, Esteban,
I recreated the jar and it does contain class files with no manifest file.
It has four classes: Temperature, Room, ServerGUI and Fan - i have included
it. The four appear in Imported types of the package main menu but i still
get the same error when i try to save and validate configuration.
Kind regards,
James.

Drools Flow - users authentication.
by tom ska
Hello,
I want to try Drools Flow software (Eclipse plugin works). I have installed
Guvnor. Then I have installed console (two wars). I type
http://localhost:8080/gwt-console/app.html in my web browser. Then I get a
dialog, and I have to authenticate. But I don't know default Username and
Password. As far as I know, I have to create a XML file, and manually create
a user and his pass... Am I right? I use Drools Flow Console v.2.1.
Please help me, and do it slowly and like for no-IT person ;)
Thanks, tom.
