[m_qasim26]

Hi,

Code:

            Map params = new HashMap();
            params.put("Id",25);
            InputStream reportSource = ClassLoader.getSystemClassLoader().getSystemResourceAsStream("templates/account.jasper"«»);
            JasperReport jasperReport = (JasperReport) JRLoader.loadObject(reportSource);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, DBUtil.getConnection());
            JasperViewer viewer = new JasperViewer(jasperPrint,false);
            viewer.setVisible(true);
viewer.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
            reportSource.close();
