error compiling BigDecimal values

2005-12-18 08:28

the three variables are define like BigDecimal, so, I cannot understand which is the problem

 

ingresoNeto:

clastype: java.math.BigDecimal

calculation time: Nothing

reset type: Report

variable expresion: $V{totalIngresos}-$V{totalEgresos}

 

totalEgresos and TotalIngresos have no variable expresion because they are returned values from subreports which are also java.math.BigDecimal

 

net.sf.jasperreports.engine.JRException: Errors were encountered when compiling report expressions class file: 1.

The operator - is undefined for the argument.

 

I checked out java.math.BigDecimal, found here:

http://java.sun.com/j2se/1.4.2/docs/api/java/math/BigDecimal.html

 

instead of having: $V{totalIngresos}-$V{totalEgresos}

 

try:

$V{totalIngresos}.subtract($V{totalEgresos})

 

 

Hope that helps.

(Perhaps if you get the chance you can help me:
