Drools Licence
by Anderson Neves
Hi everybody.
Can Drools be used in a commercial application? Like Hibernate can. I read
the licence, but still have doubts.

Drools server deployment
by Sébastien Raickman
Hi all,
I am working with drools-server linked to Guvnor repository by a changeset
where my URL package/snapshot is defined.
Both of them are running on the same Jboss server instance
(drools-guvnor-5.1.1 and drools-server-5.1.1)
First, as the default deployment order is alphabetical, guvnor is deployed,
and that's what I need.
But when drools-server si deploying, I have the following error:
It seems that is caused by a timeout exception...
After Jboss has started, I touch web.xml on drools-server.war and everything
is deployed...
Any idea??
Thanks
Seb

How to manage lists of data
by Alexander, Scott F
Hi,
Im pretty new to drools and have been going through the docs for the Expert and guvnor. I have some basic unit tests running with the rules I am trying to replicate from a legacy system. One of the rules my current system uses is to check a property in an Object against a list of values and fire if the property is present in the list ie list.contains(someValue);
I am trying to find out what the best practise is for setting up the lists which will be checked against. I don't want to have to include these lists in java classes and upload them as facts. I would much rather be able to manage them through guvnor so my non technical users can manage them themselves without the need to release a new jar file.
Thanks.

compare date in map in rule condition
by James Gu
Hi, I am trying to compare date in condition of rule. I set the date format
in system parameter.
System.setProperty("drools.dateformat", "dd/MM/yyyy");
When I get the date from the fact object directly, it works well.
when
$record: Record( startDate < "01/01/3000" )
In my application, I need to get a map from fact objet, then use a key to
get the target object, then get "dateValue" from the target object. This
condition doesn't work. "dateValue" is a java.util.Date object.
when
$record: Record( fieldMap["STARTDATE"].dateValue < "01/01/3000" )
Does anyone know how to make it works?
This is the error message.

Parsing problems using a DSL
by drdaveg
I have run into a number of problems using a domain specific language (DSL)
on processing DSLR files. My biggest frustration - and one I am hoping
people can provide a work-around or guidance on - is that often the Eclipse
plug-in does not allow the DRL pane, showing the DRL file, to be clicked on
(and shown.) This sometimes happens when there are no compilation errors:
the DLR file is simply not being generated.
I have run into issues where an error like "parsing problem: contact the
support team" occurs or a null pointer exception occurs, but no error is
shown. My approach has been to make small changes in working DSL files
(i.e., describing the translations) at a time, to minimize impact. Can
anyone offer better approaches to building the DSL grammar?
On a related issue, many documents cite using DSL and regular expressions
for code-rewriting and - while I find documentation on antlr 3 masks for
doing some regular expressions - is the common re-writing task of using "or"
- as in
My object (Car|Bus|Buyer|Salesman)
supported in any way other than seperate lines for "object Car", "object
Bus", etc? Thanks!

Limiting rule evaluation--not firing
by ljnelson
Hello; I am aware of the fundamental difference between inserting facts--and
evaluating them against all the rules in the rule base--and firing
rules--i.e., executing only certain rules' consequences.
I understand that ruleflow-group and agenda-group and activation-group can
all be employed to govern which rules' consequences are fired at
fireAllRules() time.
My question (which has been asked by many others in different ways, yet not
answered as far as I can tell on the mailing list to anyone's satisfaction)
is: is there any construct that can be used when it is known up front that
only certain rules will match? That is, is there any way to limit rule
evaluation?
For example, I have a series of surveys that all use the same KnowledgeBase
to govern the flow of the user through the survey. But once I've asked a
given question, then I know right then and there which rules have a chance
of taking effect.
I've already put them in their own agenda-group, and I already switch focus
to that agenda group prior to fact insertion, so that by the time I call
fireAllRules() I've made it so that--say--ten rules' consequences are the
only ones (out of hundreds) that could possibly fire in this given session.
But unless I'm radically misunderstanding something, each time I insert a
fact, it is evaluated against all the hundreds of rules, even when several
hundred of those rules don't have any chance of having their consequences
firing.
I even understand (I think) why this is. If I were, for example, to
subsequently pop the agenda group that I had set focus to, then "MAIN" would
be selected, and for those activations to fire the inserted fact would have
had to have been evaluated against all the rules, including those whose
agenda group is "MAIN".
But I guess what I'm wondering is: can I somehow turn this off? Can I, in
other words, partition the KnowledgeBase itself? Can I effectively tell
Drools, during this stateless session, don't even bother trying to match
facts against rules 1-10, just try rules 11-14?
Thanks,
Laird

Drools 5.1.1 : Error reporting issue in PackageBuilder
by arjun dhar
Hi,
I was trying out the new stable version of Drools and on faulty DRL files I was getting:
Exception in thread "main" java.lang.ArrayStoreException
at java.lang.System.arraycopy(Native Method)
at java.util.ArrayList.toArray(ArrayList.java:306)
at org.drools.compiler.PackageBuilder.getErrors(PackageBuilder.java:1274)
at org.drools.builder.impl.KnowledgeBuilderImpl.getErrors(KnowledgeBuilderImpl.java:70)
at com.arjun.SetGame.main(SetGame.java:18)
The actual Error being:: (See Reference DRL at the end of this post)
[Unable to resolve ObjectType 'MockBoolean' : [Rule name='show_time']
, Incorrect number of arguments for interval timer 'int 5s 2m']
I'd assume it be better to have an Exception with the root cause, than a faulty Error trapping system, that is trapping a System generated Exception. Is this a bug in "PackageBuilder : Line 1274"?
Reference DRL:
package com.arjun
rule show_time
timer (int 5s 2m)
when
MockBoolean(value == true)
then
System.out.println("Hey");
end

Migrate from JBRMS 4.0.7 to Guvnor 5.1
by smolnij
Hello all
I need to migrate from 4.0.7 drools to 5.1, could you please give some
advices and links?
We have drools JBRMS 4.0.7 app with lots of rules, persisted in Oracle. We
haven't any .drl files for these rules. I've tried to export these rules via
export feature from JBRMS 4 and then import the derived XML via import
feature in Guvnor 5, but I get the following error:
17:56:55,365 INFO [STDOUT] ERROR 16-03 17:56:55,361

Is there some way how we can transfer the rules from JBRMS to Guvnor? Does
the Guvnor has another rules format, so it can't import from JBRMS XML? Is
there some specs about differences, so I would be able to write the
converter? Or is there some already published converter?
Would it make sense to export the rules via JCR API from old JBRM JCR (1.3)
and then import it to new JCR repo created by Guvnor?
How we can upgrade the drools version without loosing our already created
rules?

Question regarding drools example
by DECOUX Yannick
Hi,
I'm new to drools and i'm trying to learn through the drools examples.
Inside the file org.drools.examples.process.order.logging.drl I see this :
workItem: WorkItemImpl( state == WorkItemImpl.PENDING ) from workItemNodeInstance.getWorkItem()
The PENDING constant seems to be missing in the org.drools.process.instance.impl.WorkItemImpl class
Am I missing something ?
Thanks
