[swarupakp]

Hi,

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..

at net.sf.jasperreports.engine.fill.JRExpressionEvalException: Error evaluating expression :

Source text : $F{QTY}
