java - Problems to access a report in a jar file

Question

I have a jar application that contains several reports (files .jasper) and the way that I get the path of the report is:

getClass().getResource("/reportes/mireporte.jasper").toString();

but when I execute I get the next error: FileNotFoundException although the report is within the jar file when I open it with the winrar.

My questions are:

1. Is this the way to get the path of a report in a jar files?
2. Is it possible to open reports that are within of a jar file?

Answer 1

Why are you converting the resource to String ??

Try to use (depending on how you want to use the resource):

• getResource("/report/mireporte.jasper").getFile()

• getResource("/report/mireporte.jasper").getInputStream()

Returned object from 'getResource' is URL:
