JasperFillManager.fillReport expects the first argument to be that path to a compiled report (*.jasper) file, you have to first compile your report (see JasperCompileManager).

You can compile the report in iReport by clicking the "Compile" button found before the "Execute" buttons. The compiled report will be saved in the directory configured as default compilation directory.

 

If you intend to learn how JasperReports and iReport work, make sure you check the documentation pages here and here.

Hello!!!

When I compile the file *.jrxml iReport generates a file *.bak, not *.jasper. How can I do it to take an *.jasper file??

Thankx men! ;)

Are you looking into the compilation folder (see Options/Settings/Compiler)?
