[rules-users] Anyway to get Failed Reason for Failed Rule?

[Zhong, Jason]

A simple solution is to pass in a string list and for each rule that is fired, append the rule name to the list. Example

In your Java code declare:
class RuleLog {
	List log = new ArrayList();
	public void add(String logEntry) {
		log.add(logEntry);
	}	
...
}

Then insert an instance of RuleLog as a fact to the rules engine. The log entries generated can be retrieved after the rule session is completed.

In your rule:

rule "foo"
   when 
	....
	logger: RuleLog()
   Then
	// this will add the current rule name to the log when this rule is fired
	logger.add(drools.getRule().getName())
	...
end

Hi Davide, your second guess is right. Sorry I should have said failed
condition.

I wanted to know which rule got fired and which one did not (because the
condition failed in when clause).

I wanted to know those, because we have requirement which asks for what are
the rules which have passed and failed copnditions, so that we can make some
decisions.

Also, I wanted to know that in a rule

rule "name"
when
    //condition
then
   //consequence
end

when the condition is failed will the rule goes to consequence or not.  (I
am fairely new to Drools. sorry).

Thanks.
