Hi,
I have this in my DSL consequence :
{name}.{indic}+:{value}={name}.putIndicator({indic},{name}.get({indic})+{value});
{name}.{indic}:{value}={name}.putIndicator({indic},{value});
If I write in my dslr :
...
then
ex.+:200
ex.:200
end
the mapping is :

Hi!
I have a server which uses a Drools RuleBase to evaluate about 2500 rules.
The server stores the Drools RuleBase in a database as a serialized java
object. I also need to transfer the Drools RuleBase to clients for offline
usage. For the server, I need fast loading of the Drools RuleBase.
I did some first tests with BRMS and also with the IDE editors,
I like the features of BRMS like Categories and I like it to use a web
interface,
so Business users can take a look at the rules and verify them
developing of the rules is much easier using the eclipse editors with
context-assist,
Hi,
I have a question regarding the way of saving the values of some static
data, wich will be used by the drools engine to calculate the price for some
product. I will explain it with the following example:

can someone tell me, when to use java or mvel as dialect ?
I've experienced that in some cases inside the drl editor using java
gives me more context-help then using mvel
but: what can I do with java and not with mvel
and what advantages has mvel compared with java
which dialect is more

Hello,
I have many problems to integrate Drools in my existing Application that is
running on JBoss AS 4.0.5 GA.
When I try to load and execute the rule-file I get the following Exception:
java.lang.RuntimeException:
As the error message states, you probably forgot to define a package name
in your DRL files.

Hi,
It doesn't work.
With :
[consequence][]{name}.{indic}\+:{value}={name}.putIndicator({indic},{name}.get({indic})+{value});
this code :
ex.\+:200
is mapping like that :
ex.+:200
For information, I use the 4.0.1 Drools.
thks,

Drools-solver solves planning problems.
It has moved to trunk and the reference manual is now available at:
http://users.telenet.be/geoffrey/tmp/solver/manual/html_single/
It's still experimental though.
We even made 2 blogs about it for the price of one:
No, you only need to escape the DSL mapping... not the actual code (BTW,
'.' is a wildcard in regexp, so I recommend escaping it too):
[consequence][]{name}\.{indic}\+:{value}={name}.putIndicator({indic},{name}.get({indic})+{value});
Should work with:
then
ex.+:200

Geoffrey,
In a bizarre co-incidence I had just finished reading the Drools solver
docs. It's very good - it's taken one of the ideas that I'd been mulling
over and implemented it a (good) way that makes me realise I'm hardly out of
Kindergarten with this stuff :-)

Java is more mature in tooling and implementation and is still currently
the default implementation and the recommended one if you are not sure.
MVEL will eventually become the default dialect when it matures, its
advantage is in the simpler language it provides, which helps make rules
easier
Yep, I am gonna implement the contest examples of itc2007:
http://www.cs.qub.ac.uk/itc2007/
They are nicely documented, use a lot of data and deal with lesson
scheduling etc.
And of course, it would be cool to win the contest with drools-solver :)

BTW, when using Java, is there a way to save the .java files created
by the compiler? I would like to understand the specific
environment/scope in which consequences are compiled. Right now, if
something goes wrong, the .java are deleted right away. I looked at
PackageBuilderOptions, but didn't

Mark,
yes, I've seen this editor - looks really nice and is the best if

do import statements have any impact on the performance of a .drl or .rfm ?
I plan to make some templates (.drl and .rfm) to use by the business guys -
from my UML model I know which entities were used from which Services,
so I can pre-configure a .drl/.rfm for each service (= drool package) and
has anyone a short info for me ?
thx

If so, I vote for an enhancement request that let's drool dump the Java files.
will consider for 4.2.
On a separate note, how would I be able to pre-compile sets of rules -
would this process involve calling
