Hi, I'm just started using JasperReports and using it with the iReport plugin for Netbeans IDE. In my reports I like to perform calculations beyond simple arithmetics locally in the report file. I want to access my calculations in static methods in a java class located in the same package as the application that is producing the reports. I can't seem to find out how to call these static methods from the variable expression. I would like to do something like this: "comp.reg.reporting.UtilMethods.calculateSomething($F{val1, $F{val2})", where the "comp.reg.reporting.UtilMethods" is the full package path for the static method "calculateSomething()". How would I formulate the variable expression and how to organize the static method class path to be able to call the method and use the returned value in the expression?
