RE: [rules-users] RE: Duplicate check using dialect(firing multiple times)
Edson,
With this code it is firing. But it is firing 2 times(u also got same 2 time
output). why is that? how we can avoid?
Thanks and Regss,
Basha
Sorry, my mistake. "this" is a reserved word in java (duh!!), and so you
need to use your own binding:
m : Message( $message1 : message )
mdup : Message($message2:message==$message1,eval(mdup != m) )
You can't use mvel dialect, because in MVEL the operators "==" and "!=" will
call the equals() method anyway.
Other than that, it is working just fine for me:
rule "Find duplicates"
salience 10
when
$f1 : Message( $m1 : message )
$f2 : Message( $m2 : message == $m1, eval( $f1 != $f2 ) )
then
System.out.println( "FIRED DUPLICATE:" );
System.out.println( " $f1 = "+$f1+" [ message="+$m1+" ]" );
System.out.println( " $f2 = "+$f2+" [ message="+$m2+" ]" );
end
rule "Find differents"
when
$f1 : Message( $m1 : message )
$f2 : Message( $m2 : message != $m1 )
then
System.out.println( "FIRED DIFFERENT:" );
System.out.println( " $f1 = "+$f1+" [ message="+$m1+" ]" );
System.out.println( " $f2 = "+$f2+" [ message="+$m2+" ]" );
end
The code to insert facts is:
Message message1 = new Message();
message1.setMessage( "Hello World" );
workingMemory.insert( message1 );
Message message2 = new Message();
message2.setMessage( "Hello World" );
workingMemory.insert( message2 );
Message message3 = new Message();
message3.setMessage( "Hello Bob" );
workingMemory.insert( message3 );
workingMemory.fireAllRules();
And the result is:
FIRED DUPLICATE:
$f1 = [EMAIL PROTECTED] [ message=Hello World ]
$f2 = [EMAIL PROTECTED] [ message=Hello World ]
FIRED DUPLICATE:
$f1 = [EMAIL PROTECTED] [ message=Hello World ]
$f2 = [EMAIL PROTECTED] [ message=Hello World ]
FIRED DIFFERENT:
$f1 = [EMAIL PROTECTED] [ message=Hello Bob ]
$f2 = [EMAIL PROTECTED] [ message=Hello World ]
FIRED DIFFERENT:
$f1 = [EMAIL PROTECTED] [ message=Hello World ]
$f2 = [EMAIL PROTECTED] [ message=Hello Bob ]
FIRED DIFFERENT:
$f1 = [EMAIL PROTECTED] [ message=Hello Bob ]
$f2 = [EMAIL PROTECTED] [ message=Hello World ]
FIRED DIFFERENT:
$f1 = [EMAIL PROTECTED] [ message=Hello World ]
$f2 = [EMAIL PROTECTED] [ message=Hello Bob ]

i just use this sort of rule
rule "Hello World"
dialect "mvel"
when
m : Message( $message1 : message )
mdup : Message($message2:message==$message1,eval(this!=m) )
then
System.out.println("Rule Fired"+m +"::"+mdup );
System.out.println ("Rule Fired"+$message1 +"::"+$message2 );
end
if i put rule parameter dialect "MVEL" the error "this should be used

i assert 2 objects with message Hello and Hello1.
still the rule is firing(2 times).

[rules-users] mvel regex not working???
Hi,
I have an email validation regex where the mvel matches doesn't seem to
work. I have created 2 rules where test1 uses the Java String matches
and test2 uses the mvel matches. Test1 works but test2 doesn't. I am
using Drools 4.0.3 and JDK 1.6.0_02.
rule "Test1"
when
// This works
email : String()
eval( !email.matches(
"^[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+(
\\.[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+
)[EMAIL PROTECTED]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(\\.[a-zA-Z0-9]([a-zA-Z0-9
-]{0,61}[a-zA-Z0-9])?)*\\.[a-zA-Z]{2,6}$" ) )
then
System.out.println( "1-Invalid Email Address: " + email );
end
rule "Test2"
when
// This doesn't work
email : String( toString not matches
"^[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+(
\\.[a-zA-Z0-9\\!\\#\\$\\%\\&\\'\\*\\+\\-\\/\\=\\?\\^\\_\\`\\{\\|\\}\\~]+
)[EMAIL PROTECTED]([a-zA-Z0-9-]{0,61}[a-zA-Z0-9])?(\\.[a-zA-Z0-9]([a-zA-Z0-9
-]{0,61}[a-zA-Z0-9])?)*\\.[a-zA-Z]{2,6}$" )
then
System.out.println( "2-Invalid Email Address: " + email );
end
Here's the output using email addresses [EMAIL PROTECTED] (valid) and x.xx.com
(invalid):
test1-Invalid Email Address: x.xx.com
test2-Invalid Email Address: [EMAIL PROTECTED]
test2-Invalid Email Address: x.xx.com
The regex expressions are exactly the same. Am I doing something wrong
here?
Thanks,

[rules-users] Is InternalRuleBase safe to use?
Hi,
re:Drools 4.0.3
I want/need to use ConsequenceExceptionHandler for exception handling.
I'd like to be able to get the ConsequenceExceptionHandler from a
StatefulSession.
The only way I see to get the handler relies on InternalRuleBase.
The JavaDoc at http://downloads.jboss.com/drools/docs/_
4.0.3.15993.GA/apidocs/org/drools/common/InternalRuleBase.html
does not have any annotation that it is internal use only. However the naming
convention sure makes me this this is a bad idea.
Any alternatives to the following code to retrieve the
ConsequenceExceptionHandler?
InternalRuleBase thisSmellsLikeABadIdea= (InternalRuleBase) wm.getRuleBase();
DroolsExceptionHandler deh = (DroolsExceptionHandler)
thisSmellsLikeABadIdea.getConfiguration().getConsequenceExceptionHandler();
List exceptions = deh.getExceptions();
(Where DroolsExceptionHandler is
package droolsconfig;
import java.util.ArrayList;
import java.util.List;
import org.drools.WorkingMemory;
import org.drools.spi.Activation;
import org.drools.spi.ConsequenceExceptionHandler;
public class DroolsExceptionHandler implements ConsequenceExceptionHandler {
List exceptions = new ArrayList();
public DroolsExceptionHandler() {
}
public void handleException(Activation activation, WorkingMemory
workingMemory, Exception exception) {
exceptions.add(exception);

public List getExceptions() {
return exceptions;

[rules-users] howto BRMS - already stuck at fact model loading
Hey all, new to BRMS as trying to learn how this works. My usecase is to take an existing, working EJB3 application and migrate some of the complex rules over to be managed by BRMS. However, initial attempts over the course of a couple of days have yielded zero results. When trying to follow http://downloads.jboss.com/drools/docs/4.0.3.15993.GA/html_single/index. html#d0e5301, they want you to load a fact model. I take an existing EJB3 entity bean and it loads fine. There doesn't seem anything more for me to do, or to verify this is o.k. or not. So, then I move to the rule editors, and nothing works - not able to use the guided editor at all, and using the DSL text editor with the 'model/entity' from the jar isn't recognized. Now, I admit ignorance, and I would like some direction as to how to best learn to use BRMS. There were a couple mentions of a drools-examples-brms, but it just can not be found. Following the documentation mentioned above is only guidelines without any good examples leaving one easily lost. http://www.google.com/search?q=drools-example-brms http://www.nabble.com/forum/Search.jtp?query=jbrms+example&local=y&forum =11822&daterange=0&startdate=&enddate= http://labs.jboss.com/drools/downloads.html http://labs.jboss.com/drools/livetrails/index.html So - where can one go to learn how to use BRMS to help convert an existing EJB3 application to use Drools and BRMS?

RE: [rules-users] RE: how to find duplicate inlineeval
Edson,
As you said i used inline eval. But am getting erroe message like this can't be
used in static context.am using statelesssession to assert my objects.
i also put eval(this!=obj1) as follows.
$obj1:Object1($id:id,$name:name)
$obj2:Object1(id==$id,$name:name==$name, eval( this!=$obj1 )) eval($obj2!=
$obj1)
Though my references are different the rule is not firing
Thanks and Regs

Subject: Re: [rules-users] RE: how to find duplicate
Sikkandar,
The only way to check for identity is to use an inline eval and use java
code to check that:
when
$obj1:Object1($id:id,$name:name)
$obj2:Object1(id==$id,$name:name==$name, eval( this!=$obj1 ))
then
Another option is to configure your rulebase to not allow the same object to
be matched by more than one pattern in your rules. To do that you can either
set a system property:
drools.removeIdentities = true
Or you can use drools API:
RuleBaseConfiguration conf = new RuleBaseConfiguration();
conf.setRemoveIdentities( true );
RuleBase rulebase = RuleBaseFactory.newRuleBase( conf );
If you do that, your rule can be written as this:
when
$obj1:Object1($id:id,$name:name)
$obj2:Object1(id==$id,$name:name==$name)
then
Since the engine will never allow the same fact to simultaneously match both
patterns.

2007/11/13, Sikkandar Nawabjan <[EMAIL PROTECTED]>:
Hi,
am passing list of objects to working memory. i want to fire the rule
if there is any duplicate objects in the list
i write code like this
when
$obj1:Object1($id:id,$name:name)
$obj2:Object1(id==$id,$name:name==$name,this!=$obj1)
then
fire rule
Now the problem lies at this!=objj1(a highlighted check). i put this to
avoid a object check with itself.
But this is internally calling equals method of the corresponding
object and always return true. Because i overriden equals method in the Object
itself
so at the end the rule won't fire even if there is a duplicate object.
how i can solve this
equals(Object obj){
if(this.id=obj.id&& this.name==obj.name)
return true;
else
return false;
}

Yes, thanks for your help. I'll try your suggestion for #2.
I resolved the deployment problem by myself. It was just a mistake with
the JBoss ESB deploying...
But now I have another problem. The rule file is found, but there seem
to be some problems with the parser.
The FireRulesActionHandler class from the jbpm wiki uses the following
code:
RuleBaseImpl ruleBase = new RuleBaseImpl();
ruleBase.addPackage(pkg);
But the RuleBaseImpl class doesn't seem to be part of drools anymore. I
looked at the javadocs to find a replacement. I've found the
RuleBaseLoader class which looked like what I needed. I replaced the two
lines with this:
RuleBaseLoader rbl = RuleBaseLoader.getInstance();

[rules-users] create .pkg file with or without BRMS
Hi, I'm using BRMS to generate a .pkg for an application i need to generate the same file without BRMS: i'm trying to use a drools-ant task, but, pkg file generated with drools-ant task is not the same !!! i don't found a specific documentation to do that ? Somebody can help me please ? thanks for your help ___ rules-users mailing list rules-users@lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
[rules-users] Fire Rules in DT based on a rule in DT
Hi, I have the following scenario. SCENARIO (simplified for discussion from actual blown up scenario) - 1. A decision table (DT) with rules for "all types of employees" - Call it "Common DT" 2. The DT mentioned in Point 1 has a condition that fetched data depending on "Type Of Employee" 3. There are other decision tables that would like to use the the rules from "Common DT", but here are the challenges: Challenges -- 1. Decision does not support Agenda Groups 2. Using a fact; to hold the evaluated result from a DT can pass it from a child to a parent; but it requires an "update()"; which can cause infinite recursion if i dont have a "Execute ONE Rule Only from Table" decision variable. (Parent) DT - Condition 1, condition 2, Condition 3 (Actually result of Child DT) (Child DT) ... The relation is maintained using decision variables. This relation works perfenctly good (been working for 3 months now), but issue is it creates a Sort of a Tree (with each node a DT); in shich I cannot fire a common set of rules from Any Node. As an alternative; I'm suggesting to the client to write replicated DT's for each type of employee instead of 1 generic DT. Can anyone help? I've been begging for agenda Groups in decision tables but I guess you guys are tied up. So at a design level can you suggest a work around?
