Jasper reports - byte data not found

Flow
1

I have a Jasper report that has a logo on it, but Vaadin in production mode cannot find this logo, even though it exists on the server.

HashMap<String, Object> param = new HashMap<>();
        param.put("logoCupom", "C: " + File.separator + "Agil" + File.separator + "Logos" + File.separator + "PortalParceiro" + File.separator + "EAS.png");
InputStream src = getClass().getResourceAsStream("/reports/Contrato_Prestacao_Servicos.jasper");
            JasperPrint jp = JasperFillManager.fillReport(src, param,
                    new JREmptyDataSource());
            JasperExportManager.exportReportToPdfFile(jp, contratoLocal.getPath());

It looks like a JasperReport related issue. Please check server logs and see if there is a stack trace that could help identifying the issue.

4

it works in dev mode though, strange

5

Yeah. Hopefully the stack trace can point you to the cause of the issue

the stack trace says nothing sadly

Do you mean there’s no stack trace at all?
