Salience is just one way to force the evaluation of a condition before
others. In fact, using salience throughout is just a way of re-creating a
sequence of plain old if statements using a rules engine.
I'm not going to waste my time and yours by elaborating on possible
alternatives unless you com

Hello,
I submitted some issues to the issue tracker and browsed the issue tracker
site. Found that there is a bug fix version for drools 5.3 final which
named '5.3.2.final'. But I can't find where to download it.I searched for
the droolsjbpm/drools github repos too, but still couldn't find.
So if s
What Wolfgang was hinting at (assuming I understood correctly the thread of
the discussion) is the difference between a set of rules like this:
...
rule "n-th test"
when
$b : Bean( field == "x_n" )
then
$b.setSomething( "y_n" )
end
...
and rule-base like this:
declare Holder
selector
I am not sure I understand that. What is the other option for this case.
Why would simple rules not work for 20 K rules. Am I missing something. I
cannot use database to store my rules. Drools also gives me salience which
I need for my usecase.

Thanks for the reply Mike & Esteban Aliverti. Using the webdav i was able
to see the xml format of the rule through

Guvnor uses JCR (Jackrabbit or Modeshape).
JCR can be configured to store it's binary data in a database.
The configuration you make to Guvnor to use a database configures JCR.
The resulting tables are of JCRs requirements and needs. As you have
discovered JCR has no knowledge of "rules".
You c
Guvnor relies on JCR to persist its data. Maybe there is a way to configure
Jackrabbit (the JCR implementation that Guvnor uses by default), but I
don't know.
Webdav is another way to access the assets inside guvnor. Using a webdav
browser (I think Internet Explorer is one. Another one is Nautilus)
Thanks for the reply. Can you tel me what is webdav? Also, is there any way
that i can change format of JCR? Because right now, i see a table called as
versioning_pm_refs under my guvnor database which has some kind of data
something like this in the field node_id. When i tried adding a new rule, i
Even if you have configured a database to store your rules, JCR is using
its internal format to store them. Not sure if you will be able to see them
in any readable way.
Did you try using webdav?

Hi all,
I have installed Guvnor 5.3.0-Final on a fresh Tomcat 7.0.12. I am able to
import existing rules I have, however when I try to upload my fact model I
get an error in the localhost log file:
SEVERE: Servlet.service() for servlet [AssetFileServlet] in context with
path [/guvnor-5.3.0.Final
"dialect" is for areas explicitely marked with "eval" and for the
consequence.
Over time we have improved the capabilities of the parser and thus the
pattern language, so that much more can be done without the need of
using an eval, the stuff outside of the eval is not related to the
"dialect"
Hi,
I want to write the rules from drools to my mysql database. Using Repository

Also - I just confirmed that getFoo1AsBoolean() returns null. I appreciate
that as part of Drools null protection I don't get an error on that ...
however, I am curious why the rest of the expression (the right hand side of
the &&) is even evaluated.

Hi,
Sorry to have kept you waiting.
If you use plain DRL, you have 1 source of information. If you use DSL, you
add an extra source of information by inserting the data in it. Adding DSL
on top of that, adds a third source of information in the form of a
vocabulary.
In theory, the more disperse
Yeah, I'm aware of that. Still, I find it easier, even for a unit test, to
write a DRL snippet
rule "initTest"
when
then
SomeFact sf = ...
insert( sf );
end
and add this in the setup, possibly even compiled from a java.lang.String.
YMMV.

Ok laune, but I would like to create this objects inside a junit test (so in
a method defined in a *.java file), not from the drl itself. Were you
suggesting a workaround?

Hi,
I have declared a fact in a drl file as follows:
package a.b.c
declare MyFact
vehicle : Vehicle
end
The corresponding class file doesn't exists: it is created on the fly by
drools at runtime. The class name should be a.b.c.MyFact, but the
classloader cannot find it by using:
Class c =
