Hi, I have created a report book because I need portrait and landscape orientations in the same report. But it is always blank when I try to export it to pdf with my java project (JasperPrint jasperPrint = JasperFillManager.fillReport(reportStream, params, con);). It works for other reports and I also have datasource and query defined which seems to be the problem for others. Is it even possible to export report books with java?
