[rules-users] Can we return values from rules to java ?

[FrankVhh]

Hi,

I want to correct myself on my point about passing the variable to JAVA. You
should probably add an array of strings to some object and for each rule,
add a string to the list.

rule "Hello World"
	when
		m : Message( conditions )
	then
                // 
		m.addRuleToArray( "Hello World" );
		update( m );
end

In your Java code, add an array of strings (or integers or whatever,...),
write a function to add information to the array and just call that function
from within your rule. All fired rules will be added to the array and will
be available to you in Java.

regards,
Frank
