I have added new Variable TotalQty.In that TotalQty Properties wise i have converted String field value to Integer by using new Integer($F{QTY}} .
And Varibale Type is ---> java.lang.Integer
and Calculation Type is ---> Sum.
and Variable Expession is ---> new Integer($F{QTY})
when i m running the report in iReport its generating the report but i m calling that .jasper file from my JSP Page its showing the following error..
