Hello:
There are n selection criteria from s1 .. sn for each item i1.. in. Each
item can have a subset of criteria which applies to them.
The end user, can choose a subset of criteria like c1 and c5 and only the
item that has c1 and c5 valid should be returned. For example: if item i1
and i2 have
You need to create a new 'default' package (i.e, not the 'defauktPackage'
that comes with Guvnor) and upload your ruleflow.

Hello,
I'm feeding my working memory with Maps (unfortunately, this is a
requirement and I can't use beans).
To access the values in this maps I use the following MVEL expression :
Map ( this["airportCode"] == "GIG"
, this["numberOfPassengers"] > "1"
I neglected to mention my reply is from the viewpoint of changing entities
through the program that interacts with drools; if you need to sense changes
from another source to entities/tables in a database Greg's suggestion seems
the easiest and least resource intensive. Pushed actions from the dat
Thanks Mark, sounds good. And the hashCode trick works. Wow, I would have
never thought of that!

It can depend on how you want to use working memory as well. If you are
working statelessly, you can load objects through some type of transactional
framework, insert them into memory (or the ones relevant to you at that
moment in time) let Drools evaluate the objects, make changes and then
serial
I am also looking similar feature. We can currently use AOP to send event to
stream. However, we have events with relevant duration for days and some
time weeks. If server were to restart for maintenance, how do we restore to
the same state?

Yap, that or, in case you want to do it automatically for ALL your rules,
you could use:
KnowledgeBaseConfiguration conf = ...
conf.setOption( RemoveIdentitiesOption.YES );
Javadocs:

Yap, Wolfgang has the picture right. Just 2 clarifications:
* A single pattern forall in Drools is a syntax sugar to a multi-pattern
forall in the following way:
forall( Pattern( ) )
=>
forall( $p : Pattern()
Pattern( this == $p, )
In other words, drools uses the fact type to de
org.drools.event.WorkingMemoryEventListener would be the other option, now
using changes to the Working Memory as the trigger to update the Data Base.
If you intend using rules that modify WM contents, you may have to have this
in addition to a DB change notification mechanism.-W

Here's the explanation why Tom's version does not work. The first pattern of
a "forall" defines the domain, which is: all CreditReport facts; for each
object in this domain, the remaining patterns must match; since the FICO
pattern merely ascertains the existence of a single FICO chained to a paren
