[rules-users] Dynamic Rules

Hi All, Just getting started using Drools and I have a question about dynamic rules. I have written a simple application based on one of the tutorials. Rule: rule "basic rule" when Account($balance : balance < 100) then System.out.println("Account balance: " + $balance + " is less than 100"); end This rule works fine in my test application but is there a way to replace the static 100 with a dynamic value like, AccountRulesConfig.lowBalance, basically testing against the value of another object rather than a static value? Thanks Glenn
