当 JasperViewer 出现并关闭它时，主框架/父框架也关闭[重复]

When a JasperViewer出现并关闭它，主框架/父框架也关闭了。如何防止这种情况发生？

这是我的代码..

 private void cmdprintidMouseClicked(java.awt.event.MouseEvent evt) {                                        
        // TODO add your handling code here:
        try {
            JasperDesign jasperDesign = JRXmlLoader.load("report12.jrxml");
            String sql = "select * from db1 where Company LIKE '" + txtcompany.getText() + "%'";
            JRDesignQuery newQuery = new JRDesignQuery();
            newQuery.setText(sql);
            jasperDesign.setQuery(newQuery);
            JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
            JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);
            JasperViewer.viewReport(jasperPrint);
        } catch (Exception e) {
            JOptionPane.showMessageDialog(null, e);
        }

改变这个：JasperViewer.viewReport(jasperPrint);

to JasperViewer.viewReport(jasperPrint, false);这将正常工作。
