[rules-users] How to define static constant variable

[Esteban Aliverti]

So these are not "constants" :).
I think a better approach could be to model your "constants" in a Fact
class.
Then, you can insert/update/retract this fact inside your rules.
For examples:

rule 1
when
   Something()
then
   //init "values" fact
   Values v = new Values();
   v.set...
   insert (v)
end

rule 2
when
   $v: Values()
   Other(amount > $v.maxAmount)
then
   //you can also use $v here
end


Best Regards,
