[rules-users] how to perform some task when rule fails.

Hi All, My requirment is that i want to send corresponding error when any rule fails. for example: rule "ValidationRuleExp_G250.4_0" when IValidationField(attributeId =="G250.4") (((Map( this["G250.18"] !=4))&&(Map( this["G250.4"]not in("910","990","983","995","996","997"))))||((Map( this["G250.18"] ==4))&&(Map( this["G250.4"] in("910","990","983","995","996","997"))))) then System.out.println("comming here---Success-------------------------------------------------->"); end In this case i can call some method in success,Is there any way so that i can call some method when any rule fails. the problem is that i am trying to generate rule file and all the validation expressions are already defined. my task is to evaluate these expression and generate corresponding error message when any rule fails can you please suggest me how can i do this using drools.
