[wim040]

Hi all!

New to Jaspersoft and Java, but I understand the basics. As the titles sugested, I want to export my .jasper while to .pdf, but i keep getting error messages and my pdf file won't open.

Does anyone know, why the pdf export is not succesfull? Let me know if you need more information!

Try to do outputStream.close(); after exporter.exportReport();
