People don't like dependencies, you can easily implement AgendaFilter
using commons Predicate - would make a good article for an aspiring user
:)


Good point. It just is a bit confusing at first.
How about renaming it from AgendaFilter to ActivationFilter, as it
actually deals with Activations, not Agendas...?

RE: [rules-users] RE: firing specific rule

[Manukyan, Sergey]

Ok folks, the issue was resolved, thanks everyone for their valuable
inputs.

Here is what I have found out:

1. The manual for 4.0.2 is incorrectly stating that
RuleNameEndsWithAgendaFilter("Test") filters OUT the rules. It actually
filters IN..

The interface AgendaFilter contains method : 

public boolean accept(final Activation activation);

so when it returns true - the Activation IS accepted.

The implementations class RuleNameEndsWithAgendaFilter("Test") of that
interface has method, which returns true when

 activation.getRule().getName().endsWith( "Test" )

So activations of rules that end on "Test" ARE accepted.

Documentation manual needs to be corrected and it would probably be
beneficial to add section to it describing AgendaFilter interface.

2. When using rule flow file like in my example:

START -> Initialization -> Validation -> END

And using RuleNameEndsWithAgendaFilter("My Rule Name") which had
"Validation" ruleflow group - never fired because NONE of the
activations were permitted on Initialization part, it choked execution
of the Activations on the Validation part.

The resolution was when I created a custom agenda filter :

new AgendaFilter () {

public boolean accept(Activation activation) {

if (activation.getRule().getName().equals("My Rule
Name")
||
!activation.getRule().getRuleFlowGroup().equals(
"Validation")) {
return true;
} else {
return false;
}
}   
}

It allowed to fire all rules in ruleflow group other then Validation and
then proceeded to Validation and fired that particular validation rule I
was looking for. (thanks to Kris for the advice)

I ran into this unexpected behavior as well.  I took a look at the
Drools source and found that the rule filters filter out rules that MEET
the criteria (unlike the java Filename Filter, which filters out those
that do NOT meet the criteria.

So, if you want to run a VERY specific rule, you could create something
like RuleNameNotEqualsFilter, and that would ensure that all rules
except the one you want to fire have no chance of firing.

Then, of course, you would want to make sure that the facts you assert
meet the conditions you've set up in the LHS of the rule.

RE: [rules-users] firing specific rule

[Manukyan, Sergey]

Sergey,

 

In theory you can use AgendaFilters in combination with ruleflow.  Note
however that the agenda filter will prevent certain other activations
from firing.  As a result, your ruleflow could be blocked somewhere by
not being able to execute certain activations:

 * An ruleflow group will only continue if all its activations have been
completed.  Preventing one such activation from firing (using an
AgendaFilter) will prevent the ruleflow group from completing and thus
the ruleflow from continuing.

 * Internally, the ruleflow implementation also uses rules for executing
a ruleflow, like for example when evaluating conditions in a split node.
You should make sure you do not block these rules from executing.

 

Please know that using AgendaFilters like this is discouraged.  It can
be used for testing and debugging purposes, but you should probably not
use it like this in production.  There are probably other ways to do
what you are trying to do here.

 

What would be the other way to do it? 

 

If you really want to fire only one rule for a ruleflow group, I would
suggest you make your AgendaFilter more specific, so it does not block
rules from other ruleflow groups.  You can do this by making your own
implementation of an AgendaFilter, for example a
RuleNameInRuleFlowGroupEqualsAgendaFilter, which only blocks rules in
the same ruleflow group from firing if they do not have the right name.

   Scott, both conditions are met. The problem is in
   filtering agenda to a single rule, and it only happens
when rules have
   ruleflow-group defined... 
  

If a rule defines a ruleflow-group then it can only fire when that
ruleflow-group is active. So the ruleflow-group, when active, place's
its activations onto the Agenda where when the rule is attempted to be
fired the AgendaFilter may stop that rule from firing.



The
ruleflow-group is active. Here is what I do:

 

session.insert(fact);

 
session.startProcess("Validation");

 
session.fireAllRules(new RuleNameEqualsAgendaFilter("My specific rule I
want to be fired"));  // doesn't fire any rule



Looks right

You cannot call a rule explicitely, they are not methods. 

 

I know. As I said earlier. All rules fire just fine when I am inserting
an object. But when using RuleNameEqualsAgendaFilter("specific rule
name") - NONE of the rules fire, specifically the single rule I am
interested in. Without this filter - that rule fires just fine along
with others Again this happened when rule has ruleflow-group
defined. When ruleflow-group is not defined - it fires again just fine
when using RuleNameEqualsAgendaFilter. Is RuleNameEqualsAgendaFilter
supposed to work with rules with or without ruleflow-group defined? If
so then it looks like a bug to me...

 

The agenda has the rules that are ready to fire, you can use a an agenda
filter to stop a rule firing, not to call a rule.


Do you mean using RuleNameEqualsAgendaFilter or anything else?

 

How is it supposed to be done?

You should be able to serialise a Package without having to first add it
to PackageBuilder, we have numerous  tests for this.


Mark, I looked at the test in PackageBuilderTest.testSerializable(), but
it is too syntetic, f.e. it doesn't use insert(...) function as I do in
my scenario. Please try creating a test with inserting some MyClass()
after deserializing without recreating PackageBuilder and you will see
it failing. I made many tests suggesting that. Even when I use
DroolsObjectInputStream()

what is used currently in manual... - thin italic font, how about bold

Sergey,

of course Mark is right - you shouldn't use readExternal and the default
constructor.
this was my fault from an earlier mail.

please try something like this:

// EXPORT
...
FileOutputStream fos .
...
ObjectOutputStream oos = null;
try {
oos = new ObjectOutputStream(fos);
oos.writeObject(builder.getPackage());
oos.close();
} catch (final IOException e) {
... your code
}
...

// IMPORT
FileInputStream fis...
...
ObjectInputStream ois = null;
try {
ois = new ObjectInputStream(fis);
builder = new
PackageBuilder((Package)ois.readObject());
ois.close();
} catch (final IOException e) {
...your code...;
} catch (final ClassNotFoundException e) {
...your code...;
}

now your imported package should work like the exported

RE: [rules-users] RE: rules precompilation

[Manukyan, Sergey]

wtf? you shouldn't be touching those methods, those are part of the
internal serialisation process. In fact you shouldn't instantiate a
Package at all, either serialise in an existing one 

 

So you mean do this? :

 

  ois = new ObjectInputStream(fis);

  this.pkg = (Package) ois.readObject();

  ois.close();

 

It did the same thing... threw same exception...

 

 

or use the PackageBuilder

 

How? Where is it described? Are there any examples?

Did this for some fun, will add it to the mailing lists info page on the

website. Anyone else have some more ideas? I'll blog the final results
:)

How to have your emails ignored:
Start the email with "URGENT"
Tell everyone how desparate you and how you need an immediate response 
for your really important project.
Don't wait a minimum of 3 days and resend your email within minutes of 
hours.
Send emails directly to mailing list members, especially the developers.
Paste pages of code and then say "it doesn't work, please help".
Paste a long stack trace and say "it doesn't work, please help".
Start your email with "please sirs" or include "do the needful".
Ask dumb questions that are in the manual.
Ask basic java questions.
Ask questions about JRules

Can I serialize RuleBase object in order to load later precompiled

So far I was able to do that but when inserting facts into stateful

[rules-users] agenda filter with rule flow

[Manukyan, Sergey]

Folks,

I need to use agenda filter to execute a particular rule:

rule "My Rule"
ruleflow-group "Validation"
when
Object()
then
... 
end

The rule flow "Validation" is defined.

I am doing the following:

StatefulSession session =
RuleBaseFacade.getInstance().newStatefulSession();
session.insert(new Object());
session.startProcess("Validation");
session.fireAllRules(new RuleNameEqualsAgendaFilter("My Rule"));

But it doesn't fire this rule.

Also I tried this with no success as well:

StatefulSession session =
RuleBaseFacade.getInstance().newStatefulSession();
session.insert(new Object());
session.fireAllRules(new RuleNameEqualsAgendaFilter("My Rule"));


How can I make it work?

Thanks,

[rules-users] globals in rule flow's Split

[Manukyan, Sergey]

Folks,

 

When using globals in rule flow's Split I ran into problem that changes
to the global cannot be recognized by the split and it continues to
route the same destination.

 

F.e. I have a Split with constrains. And a global TestValid object that
has one boolean attribute - hasErrors

 

global testValid

 

Split : 

-  eval(!testValid.isHasErrors())  // to No Errors action

-  eval(testValid.isHasErrors())   // to END

 

 

 

So it ends up with always looping to the No Errors Action, even though
Make Errors sets global :  testValid.setHasErrors(true)

 

In my previous example the problem was that I was not using Shadow
Proxy. But now I am and would like to use global in the split condition,

 

Please advice if it is an expected behavior and I shouldn't be using
global in split conditions...

 

Thanks,

 

-Sergey

[rules-users] Property Change Listener

[Manukyan, Sergey]

Folks,

 

In 4.0.1. When using Property Change Listener, the rule gets executed
twice when the property gets changed in the RHS of the rule, even though
I have defined no-loop in the rule

 

Is this an expected behavior? I was thinking that it should behave
similarly to the change to the object with no property change listener
with consecutive "update($o)". Which actually together with no-loop end
up in a single execution of the rule.

 

Thanks,

 

-Sergey

RE: [rules-users] rule flow --> possible bug?

[Manukyan, Sergey]

Thank you for explanations, it did clear up the picture for me, but I
still didn't resolve the problem that I am having. Looks like problem
happens when attributes are involved in a Split. Possible bug?

 

So here is an example:

 

 

 

I am inserting initially a simple TestValid class that has boolean
hasError attribute = false;

 

insert(new TestValid(false));

 

INIT ruleflow-group just prints out the facts :

 

rule "INIT"

  ruleflow-group "INIT" no-loop

  when

$v : TestValid()

  then 

System.out.println("INIT : HAS ERROR ? : " +
$v.isHasErrors());

end

 

The "Make Error" ruleflow-group is activated when hasError attribute is
flase in estValid fact :

 

rule "Make Error"

  ruleflow-group "Make Error" no-loop

  when

$v : TestValid(hasErrors == false)

  then 

System.out.println("Make Error!!!");

$v.setHasErrors(true);

retract($v);

insert($v);

end

 

 

The "Has Error?" XOR Split has the following constraints:

- TestValid(hasErrors == false)  // goes to "No Errors"
Action

- TestValid(hasErrors == true)  // goes to END

 

 

The Actions Just print out information :

- System.out.println("Init Action");

- System.out.println("No Errors Action");

 

 

When running example I was expecting to see the following events as seen
on console:

 



Init Action

INIT : HAS ERROR ? : false

No Errors Action

Make Error!!!

Init Action

INIT : HAS ERROR ? : true



 

 

Instead that is what I see:

 



Init Action

INIT : HAS ERROR ? : false

No Errors Action

Make Error!!!

Init Action

INIT : HAS ERROR ? : true

No Errors Action

Init Action

No Errors Action

Init Action

...



 

 

Now is this again expected behavior or a possible bug?

 

If it is expected then how can I make decisions based on attribute of a
fact in a Split...

 

Thank you,

 

-Sergey

true, damn :)

I did think of an attribute to "re-activate" any rules that are true,
but not currently on the agenda - but not sure about it yet, would have
to think on the negative effects some more.

Well, this won't work for the same reason no-loop isn't working: if you
use lock-on-active, it will make sure that the rule is not reactivated,
so the execution of the node will end after one increment.  But the
lock-on-active makes sure that no activation is ever created, so, in the
context of looping in ruleflow, even if the RuleSet node is activated
again afterwards, it will never increment the integer again (as you
prevented reactivation of the rule using lock-on-active), resulting in
an endless loop in this case.  Currently, as far as I know, the only
thing that works is manually deactivating the ruleflow-group.

[rules-users] rule flow

[Manukyan, Sergey]

Folks,

 

Using 4.0.1. Trying to do use rule flow to manage the execution of
rules. As I understood in Split node with type XOR I can set conditions
for each destination that are executed against facts in working memory. 

 

Let's consider I have a rule that executes every time it finds Integer
object in memory and increments it.

 

rule "Increment"

  ruleflow-group "Up"

  when

$i : Integer(intValue < 10)

  then 

System.out.println("INTEGER : " + $i);

retract($i);

insert(new Integer($i.intValue() + 1));

end

 

Now, I have the following rule flow in place: 

 

 

 

 

The Split to Up arrow has constraint : Integer(intValue < 5)

 

And initially I am inserting this fact : insert (new Integer(0))

 

Now my understanding is that It should execute rule "Increment"  5
times But instead it does it 10 times...

 

Is that a normal behavior? Why cannot Split understand that only when
there is an Integer(intValue < 5) only then execute rule with
ruleflow-group "Up"

 

Thanks...

 

-Sergey

RE: [rules-users] collect return random order

[Manukyan, Sergey]

Yang,

 

I am was suggesting to have regulation to impose particular
order(although it might be a good additional feature as well).  Would
like to just to keep the order as it was in collect list. Especially if
we are returning List that means it is an ordered collection by
definition. It looks like somewhere in the internals of collect there is
a HashSet, sitead of ArrayList used that changes the order of the items
in the incoming list, and that is what I don't agree with... I think it
must be a bug,

I saw someone is requesting LIMIT, here I saw Manukyan is asking for
ORDER BY, and also Mark is talking the FROM. Looks like the rule LHS
part would become more and more like SQL SELECT statement. :)

 

I think it is the right way. Some Stream Database also extends the SQL
to do event aggregation and correlation. The same can be applied to Rule
Engine too.

Folks,

 

When using collect on List of items with some filter (criteria), I need

F.e. I have a list of suppliers : 

 

List()  :   Supplier("FIRST", Status.ACTIVE),  Supplier("SECOND",
Status.INACTIVE), Supplier("THIRD", Status.INACTIVE )

 

And I need to find first INACTIVE supplier, so it must be SECOND
supplier.

 

So doing the following : 

 

 

When 

$l : List()  // list of suppliers

$inactive_supp : ArrayList() from collect Supplier(status ==
Status.INACTIVE) from $l 

Then

System.out.println($l); // prints FIRST, SECOND, THIRD

System.out.println($inactive_supp);  // prints THIRD, SECOND  
Instead of SECOND , THIRD 

 

 

So I am getting THIRD supplier instead of SECOND as the result..

 

Please advise if it is a bug .., or there is another way of doing
that...

 

Thanks,

Manukyan

If it is not firing, it is a bug. Although we fixed several related
bugs for 4.0.1 that shall be out soon. 
If you can provide a test case and open a Jira, I can do some
further debugging. Essentially, the difference between the rules is that
expression in the first rule is being converted into an MVEL expression,
because of the nested accessors, while the second is a pure drools
expression.

Need to have a rule that executes when there exists a Supplier with

RE: [rules-users] bug or feature not yet implemented

[Manukyan, Sergey]

Thank you Edson,

 

I am not a developer of drools, so I appreciate your sharing of design
decisions here.

 

I still wish the "field constraint" be a field constraint no matter how
this field is referenced, be it by name or by variable that references
this field, otherwise it is more like "field name constraint"

 

So I wish I could do:

 

Person( 

$a : age,

$minAge : 30,

$maxAge : 40,

$a > $minAge && < $maxAge)

 

The introduction of local variable can be helpful when field names are
complex and long (that is the case I have now), and need to be used more
then once inside of expression. Also using eval involves performance
penalty, so I would like to avoid it wherever possible,

 

Just my 2 cents...

   Sergey,

   Well, a "field constraint" must always involve a field. The decision
to have it on the left side is to simplify syntax. For instance, if you
want to write something like: "age between 30 and 40", you can do: 

Person( age > 30 && < 40 )

So you declare the field only once and can have as many expressions
applied over it as you want, using restriction connectives (&& and ||).

Now, if your expression does not involve a field, then it is not a
"field constraint". It may be an "inline-eval" (previously called
predicate expression) for instance. And in this case, you use the "eval"
keyword as showed in my previous example. 
Unfortunatelly, to avoid language ambiguities, we can't support
arbitrary expressions without a markup keyword, and "eval" was the
chosen keyword.

   That is how it is supposed to work. A field constraint in Drools
always has a field at its left side. If you want arbitrary expression,
just embed it in an inline eval:

S : Supplier( 
$sts  : supplierBusinessStatus.businessStatus,
$csts :
corporateSupplier.supplierBusinessStatus.businessStatus,
eval ( $sts != $csts )

   Although, for this specific case, it would be better (more

[Manukyan, Sergey]

Folks,

 

Using 4.0. Think I found a bug in accumulate. The variables defined
inside  cannot be recognized inside of other parts of
accumulate (action, result)

 

f.e.

 

rule ...

when 

o : Date from accumulate (  

Parent( h : height  ) ,

init(;),

action(;),

reverse(),

result( $h )

)

then ...

end

 

 

Produces : $h cannot be resolved

[rules-users] on update

[Manukyan, Sergey]

Folks,

I need a rule that will track changes to cost amount and do something
with his old value.

Like that :

rule "on updated cost write to archive old value"
when
cost : Cost()
old_cost : Cost(amount != cost.amount)  // how can I
specify the OLD cost object before it was updated???
then
... write to archive $old_cost.amount
end


Is it possible at all?

Something like in database system triggers, when you have "on update"
and then you have OLD value and NEW values available...?

Thanks a lot!

[rules-users] "contains..."

[Manukyan, Sergey]

Folks,

 

I am using MR3, have a situation when Parent has multiple Children, and
there is a rule that needs to be fired when parent has a child with
certain attribute (active == true)

 

Will need to do something like that :

 

rule

  when

 $p : Parent( active == false,  children contains Child() [ active
== true  ] )

  then

 ... register error: inactive parent cannot have active
child.

end

 

 

Please advice on correct syntaxes how to do that. Also please keep in
mind, I don't want to insert children in facts memory.

 

Thanks,

[rules-users] disable shadowing facts in MR3

[Manukyan, Sergey]

Folks,

 

I need to disable shadowing for the facts, trying to use
"drools.shadowProxyExcludes" property like this:

 

---

final PackageBuilder builder = new PackageBuilder();

 

builder.addPackageFromDrl( new InputStreamReader(
DroolsTest2.class.getResourceAsStream( "/rules.drl" ) ) );

 

Properties prop = new Properties();

 

prop.setProperty("drools.shadowProxyExcludes",
"mypackage.MyClass");



RuleBaseConfiguration ruleBaseConfig = new
RuleBaseConfiguration(prop);



final RuleBase ruleBase =
RuleBaseFactory.newRuleBase(RuleBase.RETEOO, ruleBaseConfig);

 

ruleBase.addPackage( builder.getPackage() );

 

final StatefulSession session =
ruleBase.newStatefulSession();

 

session.insert(before);

 

session.fireAllRules(new MyClass());

 

---

 

Doesn't have any effect, my class gets still shadowed to become :
mypackage.MyClassShadowProxy

 

How can I disable shadowing???

 

Thanks,

RE: [rules-users] "ShadowProxy"

[Manukyan, Sergey]

Edson,

 

The problem is for example:  I have a classes that I use with
persistance broker (OJB)

 

class Parent {

 

private Child child;

 

public Child getChild() {

 
OJBBeanManager.retrieveReferenceIfNull(this,"child");

return child;

}

}

 

He OJB broker then does this.getClass().getName() - to get name of class
requesting update of it's reference and depending on the name it
requests a proper datasource to get broker to perform transaction.

 

The name should be "Parent", but it gets "ParentShadowProxy", and cannot
find it in datasource configuration.

 

Can I disable shadowing somehow? Or what shall I do...?

RE: [rules-users] "Unable to load dialect"

[Manukyan, Sergey]

Ok, just before I submit to JIRA, I want to make sure I have a "case".
So I am using MR3.

The exception is thrown when "for" cycle is used with local variable
declared inside:

rule ""
when
...
then
for(int i = 1;;){break;}
end

it worked fine when variable is defined outside of cycle:

rule ""
when
...
then
int i = 0;
for(i = 1;;){break;}
end

Mark, please confirm that it is an issue and needs to be submitted to
JIRA,

Thanks,

Subject: Re: [rules-users] how to create local variable

 


It is not possible to assign the result of an arbitrary method call
to a variable right now. So, your best option is probably to do (please
note the use of inline-eval):

rule "SupplierView: Headquarter Supplier Code should end on 25 or 30."

  when

$cs : SupplierView(corporate == true, eval(
suppCode.substring(4, 6).equals( "25" ) || suppCode.substring(4,
6).equals( "30" ) ) )

  then

ValidationErrorFacade.getInstance().registerError($cs, new
ValidationError("Headquarter Supplier Code should end on 25 or 30."));

end


A more clean solution is to use "matches" operator. If your rule
states that Supplier Code must END with 25 or 30, you can do: 

rule "SupplierView: Headquarter Supplier Code should end on 25 or 30."

  when

$cs : SupplierView(corporate == true, suppCode matches
".*25" || matches ".*30" )

  then

ValidationErrorFacade.getInstance().registerError($cs, new
ValidationError("Headquarter Supplier Code should end on 25 or 30."));

end


Hope it helps.

//NOTE: There are 2 methods here, the one argument one is for
normal DRL.

builder.addPackageFromDrl( source );

 

//get the compiled package (which is serializable)

final Package pkg = builder.getPackage();



PackageBuilderErrors pbe = builder.getErrors();

DroolsError[] de = pbe.getErrors();



for (int i = 0; i < de.length; i++) {

  System.out.println("ERROR["+i+"]:" + de[i]);

}



System.out.println("pkg.getErrorSummary() : " +
pkg.getErrorSummary());



//add the package to a rulebase (deploy the rule package).

final RuleBase ruleBase = RuleBaseFactory.newRuleBase();



ruleBase.addPackage( pkg );

 

And here is what I got:

 

pkg.getErrorSummary() : null

Exception in thread "main" java.lang.IllegalArgumentException: The rule
called Hello World is not valid. Check for compile errors reported.

So basically - no errors...? Or ... am I showing errors correctly?

 

Also could you please specify what do you mean under "java is invalid".
You mean JDK level? I am using JANINO 2.5.6 compiler in JVM 1.4 .. is
this correct configuration?

 

 

Thanks again!

The consequence will be null if the java you used is invalid. When you
create the Package check the errors before adding it to the rule base as
you can get a lot more info. In fact thats good "best practice" always
verify that the package errors are emtpy before attempting to use the
package.

You probably need a package definition at the top of
the file.

Please also import the SupplierView class in the rules
drl file.

You can also first test using the drools sample files.

[rules-users] rule not valid...

[Manukyan, Sergey]

Folks,

 

I am using Rules 4.0 in WebSphere 6.0 app server.

 

Made a simple test file with a simple rule :

 

rule "Test"

  when

cs : SupplierView()

  then

System.out.println(cs);

end

 

 

But getting exception:

 

 

[6/6/07 16:13:06:456 EDT] 0020 SystemErr R
java.lang.IllegalArgumentException: The rule called Test is not valid.
Check for compile errors reported.

  at
org.drools.reteoo.ReteooRuleBase.addRule(ReteooRuleBase.java:263)

  at
org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:293)

 

 

 

How can I check compile errors?? And what is not valid in this rule?

 

Thanks for any ideas...

 

-Sergey

I run JBRules v4.0.x against a 1.4 JRE out of RAD7 (with a 1.4 JVM
configured) but this wasn't deployed to WAS6.0 as it's a simple
standalone app' :-(
 
I think only the JBRMS needs 1.5 JRE so you'll need WAS6.1 for this.
