Help with "contains" keyword
by Bynum, Joe
I'm doing some simple evaluation of jrules and I ran into a problem.
Here's the rule I'm having problems with:
rule "751845 - Check Stages"
when
order : Order( stages excludes 921 )
then
System.out.println( "This order contains " + order.getStages()
);
end
OUTPUT:
This order contains [804, 921]
I'm actually trying to do the opposite using 'stages contains 921'.
stages is defined as follows in the Order object.
private ArrayList<Integer> stages;
I'm using the 3.0.6 binaries on W2K w/Eclipse.
Any ideas what I'm doing wrong here?

allowing self joining combinations
by Michael Neale
I know that we by default remove self joins, ie:
when
Foo()
Foo()
will not match for the same instance of Foo - is it possible to turn that
off? I know we talked about it at one point, not sure what the latest
position is (someone was asking me and I can't recall what our final
position is). FYI Jess and Jrules both self join by default.

ClassFieldInspector and Groovy Classes
by Terry Laurenzo
The attached diff (against 3.0.5 sources) adds a condition to the
ClassFieldInspector to not analyze methods named <clinit>. For some
reason, the Groovy compiler is outputing classes that were causing
this check to choke and throw an IllegalArgumentException because of
a <clinit> method with ACC_PUBLIC access code.
Applying this patch allows Drools to operate correctly with compiled
Groovy Fact classes.
This seems like a pretty innocuous change that someone should apply
to SVN. Unfortunately, it is rather difficult to create a test case
for it.

Persistent store and web administration
by Schwenker, Stephen
Hello,
We have been using jboss rules for 6 months now and find it to be a good
tool overall. On the other hand we have noticed a few down sides.
Currently our rule engine runs on a jboss server and is deployed in a
sar. Every time we want to change the rules, we have to re-package and
re-deploy the app.
We want to advance our solution by providing a web application to
administer the rules. The first step of this will be to create a form
of persistent store for the rules. My first thought is to put it into a
database because we can then manage it easily with a web admin. Has
anyone done some work on this or can give me some ideas on how I should
start working on this? I'm willing to contribute some of my code to the
project if anyone is interested.
Thank you,
Steve.

What is the real benifit of 'From' - DB performance Vs Rete
by Arjun Dhar
Hi,
I'm aware that you are working on 'From', to pull external data and use it in
the Rule conditions for comparison with that external data.
Three Questions:
Q1. I could define my own business object that fetches in the data? Cant I?
What additional benifit does 'From' give me?
Q2. I use Decision Tables extensively; how do I use 'From' in a decision table?
is it like a Keyword,.. but I cant imagine how it would be used? Could you
please give an example.
Q3. When executing PL/SQL logic, the data is at the database itself and so is
the logic.
3.1. If we decide to abstract the logic to rules and fetch data from the
database, in theory wouldnt pure PL/SQL be faster inspite of Rete running the
logic?
3.2. Since most mainstream applications use external data, when we talk about
SPEED how significant can the rule engine be? If my conditions depend on
external data, does the speed of the rule engine really count? Unless the rule
engine is sitting inside the database I have my doubts.
... The above are pratical issues that am sure everyone would ask.
Thanks,
Arjun

Re: [rules-users] Problems with int and Integer inside Return Value and Predicate Expression
by Felipe Piccolini
I tested this changing all attributes to Long and happens the same
error:
s: Solicitud( sumaLCG: sumaMontoLCG < max, sumaGTIA:
sumaMontoGarantia >= ( new Long( sumaLCG.intValue() - min.intValue
() )) )
public class Solicitud implements Serializable {
private Long sumaMontoLCG; // suma de los montos contenidos en
cada LineaCredito contenida en la lista LCG
private int resolucion; // se guarda el RES_PUEDE_APROVAR o el
RES_DEBE_RECOMENDAR
private boolean aprovada; //si esta finalmente aprovada o no.
private Long sumaMontoGarantia;//suma de montos de garantias de
todos los productos del LCG
public Solicitud(){
this.LCG = new ArrayList<LineaCredito>();
this.sumaMontoLCG = new Long(0);
this.resolucion = Solicitud.RES_SIN_RESOLUCION;
this.aprovada = false;
this.sumaMontoGarantia = new Long(0);
}
public Long getSumaMontoLCG() {
recalculaSumaMontoLCG();
return sumaMontoLCG;
}
public void setSumaMontoLCG(int sumaMontoLCG) {
this.sumaMontoLCG = new Long(sumaMontoLCG);
}
public void setSumaMontoLCG(long sumaMontoLCG) {
this.sumaMontoLCG = new Long(sumaMontoLCG);
}
public void setSumaMontoLCG(Long sumaMontoLCG) {
this.sumaMontoLCG =sumaMontoLCG;
}

two great bugs
by Mark Proctor
Found two great bugs this weekend:
http://jira.jboss.com/jira/browse/JBRULES-778 (fixed)
when
$p : Person( $cheese : cheese )
then
modify( $cheese )
end
The above would actually use the $p fact handle for the modify, causing
the handle to reference $cheese instead of $p. This is now fixed, field
bindings now have their fact hand cleared, so on modify when the fact
handle is null it retrieves it from the working memory.
http://jira.jboss.com/jira/browse/JBRULES-780 (in the process of fixing)
no-loop is currently trapped with:
// if the current Rule is no-loop and the origin rule is the
same then return
if ( this.rule.getNoLoop() && this.rule.equals(
context.getRuleOrigin() ) ) {
return;
}
That means we have a tuple that reached the terminal node, but is not
added to the memory or an activation created and attached. Thus on a
modify or a retract the Tuple reaches the RuleTerminalNode and causes a
NullPointer.
