Use a global variable. In your java code use a property file and the "inject" to drools using the setGlobal method() of your session. session.setGlobal("maxBalance", 100) and in your drl global java.lang.Integer maxBalance; rule “basic rule” when Account($balance : balance < maxBalance) then System.out.println(“Account balance: “ + $balance + “ is less than " + maxBalance.toString() ); end From: gmacgregor(a)pocketkings.ie To: rules-users(a)lists.jboss.org Date: Mon, 8 Feb 2010 18:11:57 +0000 Subject: [rules-users] Dynamic Rules Hi All, Just getting started using Drools and I have a question about dynamic rules. I have written a simple application based on one of the tutorials. Rule: rule “basic rule” when Account($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?
