How to Multiply two Fields in iReport???

2006-02-01 21:18

Hi,

 

I have one report, which has two Fields.

One has integer value & one has double value.

I want to calculate those Fields in another variable.

 

But I got errors of Jasper.

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1. The operator * is undefined for the argument type(s) Integer, Double value = (java.lang.Double)(((java.lang.Integer)field_quantity.getValue())*((java.lang.Double)field_priceeach.getValue())); <--------------------------------------------------------------------------------------------->

 

How to multiply two fields in Jasper?

 

Plz help me out.

 

Thanx,

Deepa Kapadia

There seems to be some confusion between java objects and java primitives.

 

You're trying to apply the multiply operation (*) to two java objects... Integer and Double. You have to make your expressions the same as you would if you were wanting to multiply an Integer and a Double in a java application.

 

Instead of having an expression like:

$F{quantity} * $F{priceeach}

 

try something like:

new Double( $F{quantity}.intValue() * $F{priceeach}.doubleValue() )
