JasperFillManager null when upgrading to 6.17.0

[abdelmco]

Hi everyone, 
I'm trying to upgrade my jasperreports version from 4.0.0 to 6.17.0. But I get a java.lang.NullPointerException for JasperFillManager.fillReport (it was working very well with 4.0.0)
Any ideas where the problem can come from ?

 

JasperReport jrReport = (JasperReport) JRLoader.loadObject(getResourceAsStream("jasper/RP_FicheMain.jasper", lang));
JasperPrint jasperPrint = JasperFillManager.fillReport(jrReport, parameters, new JRBeanCollectionDataSource(demandes));

 

Many thanks

Hello,

May we please see the full stack trace of the error? Otherwise it is hard to determine what exactly went wrong. Also to clarify further, when do you get that error? When running a report? Is it happening to all reports? Or just one particular one?

Regards,

Paul
