JRDataSource dataSource = ...;
Map parameters = new HashMap();
parameters.put("id", 42);
JasperReport report = (JasperReport)
JRLoader.loadObject("c:/reports/report.jasper");
JasperPrint jasperPrint = JasperFillManager.fillReport(report, parameters, dataSource);
JFrame frame = new JFrame("Report");
frame.getContentPane().add(new JRViewer(jasperPrint));
frame.pack();
frame.setVisible(true);

The JRViewerclass is a subclass of javax.swing.JPanel, so treat it like a normal JPaneland do your stuff.
这个JRViewer类是 的子类javax.swing.JPanel，所以把它当作一个普通的JPanel来做你的事情。
