Niyas,
I tested a very resembling rule, and it works fine. I don't know what is the problem, as your code seems to be correct.The error isn't for sure the way we name the declarations.
rule "EvalWithFunction_1"
when
$e:Employee($name:employeeName == "Fred")
eval($e.getExtraHours() >= 8)
eval($e.getCurrencyName() == "EURO")
then
System.out.println($e.getEmployeeName()+" has worked at least 8 extra hours");
end
Check in working memory for facts that should activate the rule, and be sure that there are any rules in your drl file that are retracting those facts before your particular rule "Credti Accept" will fire.
Oana.

Is there any difference between the below two rules
rule "Credti Accept"
salience 10
when
cust:Customer(customerAge > 18)
then
System.out.println("Credit Card Allowed For :: " +cust.getCustomerName());
//retract(cust);
end
rule "Credti Accept"
salience 10
when
$cust:Customer(customerAge > 18)
then
System.out.println("Credit Card Allowed For :: " +$cust.getCustomerName());
//retract(cust);
end
