hello all,
Well i try to use global in one of my rules and it doesn't go well ^^.
So in my code i have declared a Boolean flagTest = new Boolean(true), set it to
a statless session : session.setGlobals("debugFlag", flagTest)and in my rule i
have put :
global java.lang.Boolean debugFlag.
When Drools does : globals.putAll( newPkg.getGlobals() ); line 495 in
AbstractRuleBase it throw java.lang.UnsupportedOperationException :-s
Is it normal or is it a bug??

Ok i found that i resolve this isue when usin an object immutable to embed my
boolean value.
But no when the global is set in the rule the rule doesn't fire any more, but if
i comment the global line the rule fires.....
Any clue?
Thanks

Globals are supposed to be immutable, specially if you are using them on
the LHS.

Effectivly, when you read the documentation it's clearly stated ^^.
But the other problem that occured was that when i put an immutable
object in my stateless session the rule won't fired.
I have found another way to achieve my goal so...

Hi Edson,
Thank you for your reply. I got the following error when I was trying to add
the package by calling ruleBase.addPackage( builder.getPackage() )
Below is the stack trace.
Exception in thread "main" org.drools.rule.InvalidRulePackage: Unable to
resolve
ObjectType 'org.drools.examples.NumberGuessExample.RandomNumber' : [Rule
name=Get user Guess, agendaGroup=MAIN, salience=0, no-loop=true]
Unable to resolve ObjectType
'org.drools.examples.NumberGuessExample.RandomNumber' : [Rule name=No more
Guesses notification, agendaGroup=MAIN, salience=0, no-loop=false]
at org.drools.rule.Package.checkValidity(Package.java:424)
at org.drools.common.AbstractRuleBase.addPackage(AbstractRuleBase.java:384)
at org.drools.examples.NumberGuessExample.main(NumberGuessExample.java:32)
I modified the NumberGuess.drl to see if the approach works. Below is one of
the rules with the fully qualified class name.
rule "No more Guesses notification"
ruleflow-group "No more Guesses"
when
r : org.drools.examples.NumberGuessExample.RandomNumber()
game : Game( )
then
System.out.println( "\nYou have no more guesses\nThe correct guess was
"
+ r.value );
System.out.println( "Your smallest guess was " + game.smallest +
"\nYour biggest guess was " + game.biggest );
end
Thanks,

Please ignore my last message on this thread. I just noticed I posted to the
wrong thread. The last message was meant for the thread with subject,
"referencing two or more classes with the same name but in different packages".
Sorry for any confusions caused,
