null pointer exception


antonj

Recommended Posts

I am running a report from inside my application.

When I run it from jBuilder it works perfectly.

When I create an executable JAR it gives me an error (see below for stack trace).

The line of code it errors on is :-

 

JasperDesign jasperDesign = JRXmlLoader.load(reportFile);

 

reportFile contans the name of the report to be run.

 

Can anyone help ?
