JasperCompileManager.compileReport - is comile report1.jrxml into report1.jasper

 

If you have already compiled report (report1.jasper) you must write:

JasperReport jasperReport1 = (JasperReport) JRLoader

.loadObjectFromFile("C:/Users/emidemi.emidemi-PC/Documents/NetBeansProjects/FleetManager/src/FleetManager/newReport5.jasper");

JasperPrint jasperPrint1 =JasperFillManager.fillReport(jasperReport1, params, conn.getConn());
