jar can't find jasper file

Hello Guys,

im developing a program which exports charts to a pdf using jasper.

The problem is here:

parameters.put("file", "statistics_summary.jasper");

So basically, i got an folder called "jasperreports-config" in my resources folder and there are some .jrxml files and this .jasper file. I added this folder as a resource in my pom.xml file so the jar knows, to look up there for this. Also, i put the path to the java build path so it shouldn't have any problems finding this file.

Now when i call:

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, beanColDataSource);

Eclipse intern it works, but the jar prints me:

Building report...
