Hi
      I have been using Drools Rules Engine in our application for past
couple of weeks.
One of the requirements in our project was to let a user (anyone who is
writing/analysing the rules) find out
what other rules a given rule depends upon. There were a few kinds of
dependencies:
1) Object Attribute dependency: The attributes of an object being used in
the conditional part of a rule
   might be getting modified in the consequence part of another rule. We
wanted all such rules with each rule having its own dependency list.
2) Rule Salience based dependency. A rule having lower salience should be
executed only after a higher (if any) salience rule has already been
executed.
3) Dependency caused by a specific Rule flow. Rules in a ruleflow group
should be executed only if (if any) Split condition gets satisfied.
4) Agenda flow dependency (i.e., one agenda following another) 
   We could not find much support for this in the Drools API. Hence we
decided to write our own dependency generator.  The tool we are writing
caters to first 3 dependencies. We might even handle the 4th one.  
  Since Drools is open source, we thought of contributing our bit towards
its development. If the drools team wants I can happily work with them on
getting this functionality plugged in the Drools system.
Thanks
Siddharth

                                        Hi guys,
The IntelliJ guys send me a new IntelliJ registration key for open 
source projects for a year.
The old one will expire soon.
IANAL, but any drools team member can use it as much as he likes for 
open source work only, as far as I know.
I 've forwarded it to mark.
Send me a mail if you want me to forward it to you too.

                                        Hello,
 
I have created few Rules using Drools. I am able execute those rule using
Drools API as well as JSR-94 API when I created them using Drools Eclipse
Plugin and stored on a file system.
 
Also, I imported same rules in BRMS Repository using Drools-Guvnor. Now, I
have few questions regarding loading/execution of  the rules stored in BRMS
repository.
 
1. How do I load rules stored in BRMS repository? As I understand drool uses
JackRabbit as its Java Content Repository. Do I need to access it via Java
Content API?
2. Is there any way to execute DSL\RuleFlow via JSR-94 API? Does JSR-94
cover these concepts?. 
 
Thanks,
Nilshan.

                                        Hi all,
 Is there a roadmap for release of Drools 5?
 When are you expecting GA release?
 Cheers

                                        Hi,
 
*        I have downloaded source code of guvnor-brms from
http://anonsvn.labs.jboss.com/labs/jbossrules/trunk/
*        Now I build it with maven using maven install command from command
prompt  in the root directory where I took the above source
*        It builds successfully and generates drools-guvnor.war on the
target folder of drools-guvnor.
*        Now when I deploy it in the jboss deploy directory and run the
jboss I get the following error
 
17:53:52,149 INFO  [TomcatDeployer] deploy, ctxPath=/drools-guvnor,

                                        What do people think of insisting on a file per type. So functions go in 
one file, rules in another and declare models in another. They all end 
up in the same package object, but we enforce a separation at both the 
file and api level.
kbuilder.addRulesFromURL( url );
kbuilder.addModelFromURL( url );
kbuilder.addFunctionsFromURL( url );
kbuilder.addProcessFromURL( url );
Really more thinking about orthogonality of api and design here. We have 
the following situation
kbuilder.addPackageFromXML()
kbuilder.addProcessFromXML()
Processes live in a package, so to a package there is no difference from 
a process to a rule - yet we are losing that orthogonality in the api to 
handle the special case.
What do people think, I'm just trying to find a better way to get some 
language orthogonality. I don't think we are likely to do this, but just 
throwing it out for discussion.
I think ideally we would like kbuilder.addResource( url/reader ), but 
not sure if we can easily determine each file type, we can't do it by 
file extensions as readers have none.

                                        Just a heads up for everyone out there. I needed to make the following
changes to guvnor's POM in order to get the webapp to work properly on
Tomcat. I would imagine some of these issues would appear on JBoss also but
have not tried.
1. Changed seam from 2.1.0.BETA1 to 2.1.0-SNAPSHOT to prevent classloader
problem

                                        I have upgrade my application to use the milestone 2 code and am having a
problem loading a package from guvnor via the rule agent. I am getting a
class not found exception for org.drools.rule.PackageCompilationData. Here
is the stack from the app. Looking at the code it appears the
PackageCompilationData has been removed.
