expander entitlement.dsl
rule "Black Berry Rule 1"
salience 1
when
Employee with attribs
- Type is 'Worker'
- Department is 'Internal Automation'
then
Log : "Entitled"
This is The DSL
[when]Employee with attribs=PersonFacts()
[when]- Type is '{type}'=type=='{type}'
[when]- Department is '{department}'=department=='{department}'

JBoss Rules IDE 3.1-M1 - Validating all *.xls files in source path?
by Bree VanOss
Hi,
I've started looking at the JBoss Rules 3.1-M1 Eclipse plugin to get an idea
of how much migration work I have to look forward to.
The first issue I ran into is that it appears the Drools Builder is
validating every Excel (.xls) file I have in my source path. Is this a
design decision and if so, how can I "hide" non-decision table .xls files
from the Drools builder? I've tried excluding them from the Eclipse Source
Path using a "source exclusion rule", but that didn't seem to work.
Thanks,
Bree

column contraint + java bean
by lucio＠asteriski.com
hi all,
having trouble with Drools 3.x syntax.
currently using one fact in working memory that is a aggregate of many
java beans. However when using the column constraint syntax it does not
seem to allow nested getXXX on the column constraint.
I have it working using predicate but it just seems verbose.
i would like to be able to fire rule when
the table object has a player count > 0 and the Table.getDealer.getFlop()
== null
how is this done on Drools 3.x?
ie.
public class Table{
int playerCount;
Dealer dealer;
Collection players;
....
}
rule "start"
no-loop true
when
table : Table( playerCount > 0 , dealerFlop :
dealer->(dealerFlop.getFlop() == null ) )
then
System.out.println( "start:" + table.getDealer().getFlop() );
end
many thanks

RE: [rules-users] Tracking non-matches...
by Michael Rhoden
Store all rules with a unique id (rule id) and keep dates of when rules
were put in/out of production. Store your net matches in a database,
after a run, and you can easily pull the delta to show what didn't
"match" on a particular day.

Subject: [rules-users] Tracking non-matches...
I was hoping for some opinions on the following:
Client will have many rules (about 1000) per RuleBase. The primary goal
is to assert Facts and find Matches in one or more rules. The secondary
goal may be to keep track of those Facts that did not produce Matches.
I was wondering what the best solution may be in this case?!
The benefit in keeping track of the non-matches would be periodic
analysis of the non-matches to discover patterns and perhaps provide
some proactive
monitoring and notification. An additional benefit may be to spot a
trend
and setup additional rules to reduce the number of non-matches.
So I would need to not only spot the no-match condition, I also need to
persist the no-match event in the database for tracking and later
reporting.
One way I can see is to assert a new Match fact the instance a single
rule is matched and then test for the presence/absence of the Match()
fact.
Efficiency and speed are paramount in our case, so I'm wondering if
there is an alternate approach that would work here.
Thanks,
James
