Hi,
Below is the code where i fire the Rule,
What i meant by "when i supply values to the above Rule" is,
In my application i have provided a place where user can enter values for
"Adult Fare", "Child Fare".... etc
so i take the values from the and set it in a bean....(u can understand from
below code)
even if the user doesn't provide the values the Rule Still Executes....
While firing a Rule it (Drool) doesn't give any error for missing
Values......
i hope u r getting what i am trying to say......
Waiting for  a Reply.

    What do you mean by "when i supply values to the above Rule" ?
    If you provide a snippet of the code you are using to assert objects
into the working memory and/or the values of the objects you are asserting,
it may be easier to understand your problem.
    It also does not seem right to declare the ApplyRuleBean pattern twice
as you are doing.
