Creating and deploying rules to Drools and JRules
by Varnit Khanna
Hi,
What will be the best way to achieve the following: We are trying to
create a simple web based interface which will allow our marketing
team to create rules and then deploy them to either jrules or drools
(depending on the client).
Is there some standard "rules language" or library available to achieve this?
Thanks,
VK

app-dev 'toe in water' help please
by dhartford
Hey all,
I'm trying to dip some toes into the water with Drools, and have an
application that would be a good start but having some understanding/lacking
an appropriate example issue.
The application context, let's say, is Mortgages, and already using the
Mortgage rules that are stored in a running instance of Guvnor.
Going back to 'toe in water', lets assume that all 'facts' are loaded on
call (so nothing is pre-loaded, all data to run a rule is supplied at the
time the rule is called). This is to make it easier to get started without
jumping all-in just yet ;-)
Using the mortgage business rule 'CreditApproval' that is already loaded
into Guvnor, I can see passing the Application object, with the creditRating
field/fact to a rule.
However, instead of populating and returning a loanApplication object, how
would I return just the decision/end result of a rule if it was only one
value (the approved/not approved decision) from the java app? KnowledgeBase
is loaded from the java app, but struggling with StatefulKnowledgeSession
versus StatelessKnowledgeSession and how to simply get back the rule
decision value (again, preferably without a specific object if it is only
one value)?
I'm also looking to only fire/execute one rule at a time for now until we
get comfortable - any help for an app developer trying to ease their way
into drools?
Sorry if I not overly clear, still trying to learn the appropriate
terminology :-)

Effective Dating of Rules
by MaverickDrools
Is there a way to effective date a rule through a program?
Requirement:
without using the Guvnor UI to write the rules, trying to upload a .drl file
using REST APIs which already has rules specified "without" the
date-effective/date-expire attributes. Is there a way to maintain versions
that could be used by effective dating the entire package itself?
Or in general, how do we effective date the rules in Guvnor without using
date-effective attributes for rules and create a knowledgebase from the
package based on the current date?
Thanks
