Re: [rules-users] Spring 4.0 & Drools 6.0.1 Integration issue

[Mark Proctor]

It’s not a known issue, but that doesn’t mean it isn’t an issue. I guess open a 
JIRA, and maybe take a look into yourself, to see if you can figure out the fix.

Re: [rules-users] Spring 4.0 & Drools 6.0.1 Integration issue

The above code works perfectly if it is a batch program.
It doesn't work in a Spring MVC web project.
Is that a known issue?

Re: [rules-users] CompositiveClassLoader$CachingLoader#load method intermittently hangs

[mikerod]

Does anyone have any thoughts on this issue?

I still haven't been able to get to the root of the concurrency issue. 
Digging through some of the Drools implementations, but no luck.  :)

Re: [rules-users] Performance of rules in Drools

[Wolfgang Laun]

"More efficient" w.r.t. runtime, maintenance, development effort,...?

Writing individual rules is quick, bad for maintenance, and probably
best, if a session has only a few inputs as it starts fast from a
precompiled rule base.

Parameter facts take a little time for development, are very good for
maintenance (see below) and have a tolerable overhead if they are not
too numerous and/or the session runs long.

What should be considered is that a set of parameter facts can be
maintained by non-technical personnel, e.g., in a spreadsheet or in
some other data preparation tool. This could be a boon for long-ter
maintenance.

Re: [rules-users] Not able to detect how to correct ERR 102

[Wolfgang Laun]

The corrected version of dsl and dslr works fine.
---
[condition][]There is a Customer with first name {name}=
 $customer : Customer(firstName == {name})
[consequence][]Greet Customer=
   System.out.println("Hello " + $customer.getFirstName());
---
package dsltest;
rule "hello rule"
when
There is a Customer with first name "David"
then
Greet Customer
end


You don't have to write the DSL all in one line. (I fixed that some time ago.)

The error message suggests that translation fails.
1) Make sure the DSLR is *exactly* as above. (The package could be
different, and there is tolerance w.r.t. spacing between words.)
2) ALWAYS print builder errors (see below).
3) Make sure you pass resources correctly to the builder. This is how
it is done for 5.x:

KnowledgeBaseConfiguration kBaseConfig =
KnowledgeBaseFactory.newKnowledgeBaseConfiguration();
KnowledgeBuilderConfiguration kbConfig =
KnowledgeBuilderFactory.newKnowledgeBuilderConfiguration();
KnowledgeBuilder kBuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder( kbConfig );

Resource dsl  = ResourceFactory.newFileResource( dslPath );
Resource dslr = ResourceFactory.newFileResource( dslrPath );
long t0 = System.currentTimeMillis();
kBuilder.add( dsl,  ResourceType.DSL );
kBuilder.add( dslr, ResourceType.DSLR );
if( kBuilder.hasErrors() ){
System.err.println( ">>> compilation errors >>>" );
KnowledgeBuilderErrors errors = kBuilder.getErrors();
for( KnowledgeBuilderError err: errors ){
System.err.println( err.getMessage() );
}
System.err.println( "<<< compilation errors <<<" );
throw new IllegalStateException( "compile errors" );
}
kBase = KnowledgeBaseFactory.newKnowledgeBase( kBaseConfig );
kBase.addKnowledgePackages( kBuilder.getKnowledgePackages() );
kSession = kBase.newStatefulKnowledgeSession();

Re: [rules-users] 6.0.1.F How to set Maven repo used by KieScanner?

[SrjTx]

Ok, so I am doing the following.

In my init, i create a container and a scanner

kieContainer = kieServices.newKieContainer(releaseId);
kieScanner = kieServices.newKieScanner(kieContainer);

Then later ,when my timer fires, call the scanner - which I know has updated
the module,
 kieContainer.newKieSession("DroolsSession")
does NOT pick up the changes.

I also tried kieContainer.updateToVersion(releaseId);
 kieContainer.newKieSession("DroolsSession")
does NOT pick up the changes.

Doing 
remove setting up the container and the scanner in init and do the
following when my timer fires

 kieContainer = kieServices.newKieContainer(releaseId);
 kieScanner = kieServices.newKieScanner(kieContainer);
 kieContainer.newKieSession("DroolsSession")
DOES PICKUP the changes.

Is this right, it seems like I shouldn't have to recreate the container?

Out of interest what JVM do you use?

We have this recorded:

JVM).

Re: [rules-users] Needs advice to help Drools on a big problem (and avoid GC overhead)

Guys,

Splitting the problem into smaller ones and retracting facts totally solved
the memory problem and also speed up the process.
I would like to thank you for your responsiveness and expertise.

I am truly amazed by the activity of this community, and Drools is an
awesome piece of software !

Thanks,
Raphael

Re: [rules-users] Efficiency questions about DSL

[Michael Anstis]

It's a deliberate decision in the workbench; as it follows what is
supported by the core engine.

I've asked the core engine developers to comment on whether the underlying
Drools engine supports (does support, should support or will support)
cross-JAR DSLs.

With kind regards,

Mike

[rules-users] Performance of rules in Drools

[Seb Geek]

Hello,

I have a list of very similar rules executed in Drools and some performance
problems appear ... I want some advices to choose between two "direction"
in order to correct them ...

First the context :
I have to execute always the same check but with different level or
"parameters".
For example,
- in the first demand (rule for our client) i have to count and retrieve
the list all Article that have a family code equals to 'A', 'B' or 'C' and
execute the then clause only if there is 3 elements in the filtered list.
- in the second demand (rule for our client) i have to count and retrieve
the list all Article that have a family code equals to 'B' or 'C' and
execute the then clause only if there is 4 elements in the filtered list
and so on ...

The number of different group of parameter values and the values of theses
parameters will change over time ...

The question is : is it more efficient to implement a lot of different
rules, each with their parameter in the code OR is it more efficient to
implement only one rule with an additional object as a drools fact
containing different parameter's values ?

Thanks for your help
Sébastien

Re: [rules-users] Not able to detect how to correct ERR 102

[Stephen Masters]

Not sure whether you reformatted the DSL for the mailing list, but it’s worth 
pointing out that each phrase defined in the DSL needs to be on a single line.

This may have changed in a newer version of Drools (my DSL runs in 5.3), but 
DSL hasn’t been given much attention for a while, so I suspect not.

Re: [rules-users] Not able to detect how to correct ERR 102

[Maxime Falaize]

Try with this :

rule "hello rule"
when
There is a Customer with first name "David"
then
Greet Customer
end

and this DSL :


[condition][]There is a Customer with first name {name}=$customer :
Customer(firstName == {name})
[consequence][]Greet Customer=System.out.println("Hello " +
$customer.getFirstName());
-


Of course your DSLR file is dependent of the DSL. Without the DSL, Drools
cannot guess what you want to do.

Re: [rules-users] How to allow non-programmers/non-Drools programmers to define rules

[Stephen Masters]

DSL is essentially just templates which map phrases (which may look a bit like 
natural language) to DRL.

DSLR is the actual rules and looks a bit like normal DRL, except that inside 
the ‘when’ and ‘then’ sections you tend to find phrases based on the DSL. This 
is the bit which could possibly be written by a fairly technical business user. 
However it’s worth pointing out that it’s pretty easy to make a mess of it.

To help avoid problems, if you have Guvnor/Workbench, then the guided editor 
supports building rules based on DSL phrases. This means that users are forced 
to pick valid phrases and use text boxes and (assuming you set them up 
properly) drop-down menus to populate many of the variables. I have had 
operations and legal teams using this quite comfortably, given a little bit of 
training and some decent documentation.

As an alternative, Paul King has done a number of presentations on using Groovy 
DSLs to build business rules. By using Groovy DSLs and an IDE, you get context 
sensitive help to generate the rules. It makes it easier to build up 
business-readable rules, although it’s probably not a solution for business 
users to write the rules themselves. You could take a look at his slides here: 
http://www.slideshare.net/paulk_asert/groovy-rules

But as Rich mentions, if you can express the rules in a table structure, then 
spreadsheets and (in Guvnor/Workbench) web decision tables are the way to go 
where possible.

Re: [rules-users] Not able to detect how to correct ERR 102

[Maxime Falaize]

The problem seems to be in the DSL file. Can you give us its contents ?

[rules-users] Not able to detect how to correct ERR 102

[ankit3j]

Below is a sample DSLR code I am trying out. Now I am getting error in "when"
block. After hours of trying to search for a solution I have not yet been
able to detect the error.

package com.sample
import com.sample.*;
//expander sample.dsl
rule "hello rule"
when
There is a "$customer" with first name "David"  // This is
where the error is
then
Greet Customer
end

[ERR 102] Mismatched input "is" in rule "hello rule"

Any idea whats wrong with this line??

Hello, 





can someone please paste me his definition of the xmlns:kie in the spring 
configuration. 

I read the documentation and I got the configuration principles, but I cannot 
find the namespace 

definition in the net. A simple paste of the header xmlns:*/schemaLocation will 
be perfect.

Re: [rules-users] How to allow non-programmers/non-Drools programmers to define rules

[ankit3j]

Thats a good point rjr201. Even I was looking to explore spreadsheet option a
little further. But the question then is how are spreadsheets
compiled/parsed into rules? Do they act as DSLs? As I want to keep it as a
code-free option for users, do I need to insert a parser to generate a DRL
file from spreadsheet?

Re: [rules-users] How to allow non-programmers/non-Drools programmers to define rules

[rjr201]

DSL's are ok up to a point. However I've found it's sometimes easier to
create very simple java classes and teach users the basics of the drools
language. 

It's really down to the problem you are trying to solve.

Have you looked into using spreadsheets? If you can fit your
problem/solution into the spreadsheet format then I would strongly recommend
you use that approach. Business users understand spreadsheets, and it
reduces the risk of users making syntax/logic errors (spreadsheets
essentially provide a template in which the user fills in parameters).

[rules-users] cannot copy guided decision table

[Ioannis Christodoulou]

I tried to copy a guided decision table in kie workbench 6.0.1.Final
It created the new decision table, but the generated drl (which can be
viewed from the 'source' tab)
cannot be validated, because the generated rule names are the same with the
copied decision table.
For example, copying the guided decision table: guided_decision_table.gdst
to rules2.gdst will not change the generated rules names, they will still
be:
rule "Row 1 guided_decision_table".

Is there something I can do about it ?

[rules-users] How to allow non-programmers/non-Drools programmers to define rules

[ankit3j]

I am a newbie to Drools and have been looking for a way to allow
non-programmers, mostly administrative guys, to define rules using a simple
language format and minimum coding terms/effort. I came across the concept
of DSL and DSLR and found it useful. 

However, it seems that to use DSL one needs to have a knowledge of
domain(Java) objects defined. Not only does it defeat the purpose it also
exposes my Java objects to users. DSLR seems to be a better alternative
which can be modified by user. But it seems that DSLR is derived from DSL. 

Which one of these 2 should actually be defined/written by user and uploaded
in the system so that backend can create rules based on it?

Re: [rules-users] Drools UI inside JSF

[Mauricio Salatino]

Hi, as far as I know there is nothing, but it shouldn't be that difficult
to create.
You will need to build a bridge between JSF and GWT and try to embed some
bits of guvnor into your JSF app.
I strongly recommend you to take a look at the new version of the tooling
which will allow you to be more granular selecting the panels that you want
to include.

[rules-users] Drools UI inside JSF

[gigu979]

Hi All,

I've a web application developed in JSF.
I need that my customers (the users) can define rules through this web
interface.

Is there any tag library or some way to translate the input data in the drl
script???

There is a way to use guvnor modules within a facelet??

Thanks

Re: [rules-users] Efficiency questions about DSL

[mfalaize]

Is it a deliberate choice to not include DSL files in the "same package" ?
If we are limited to the same folder (or same package), what do you think
about supporting inheritance in DSL files ? With this feature we could
provide to the community generic translation DSL files for many languages.

Sorry for the new questions ! :D
I'd like to help to develop but I don't want to make useless
contributions...

Re: [rules-users] Updating project repositories

[Toni Rikkola]

And Mario bounced it back into Workbench ;)

We do our deployment here.

https://github.com/droolsjbpm/guvnor/blob/master/guvnor-m2repo-editor/guvnor-m2repo-editor-backend/src/main/java/org/guvnor/m2repo/backend/server/GuvnorM2Repository.java#L197

First we install into the local. The computer where the workbench is
running.

Then we deploy into the repository that is inside the Workbench.

And then we ignore anything that is set up in the pom.xml.
