Hi, As per documentation, I'm trying to use a simple rule for date comparison, rule "EFP_14" when v:ResourceValue(QName == "A.datetime", value > "01-nov-2011") then System.out.println("--> Rule executed"); end but I get following error while executing rule. Not possible to compare a class java.util.Date with a class java.lang.String It's actually default date format so should work, why is it complaining for class casting? Am I doing something wrong here? ________________________________ BancTec Limited. Registered Office: Jarman House, Mathisen Way, Poyle Road, Colnbrook, Berkshire SL3 0HF.
