jasper reports - How to prevent parent frame closed when closing child frame (Java + iReport)?

Basically I want to call JasperViewer from a button on my Main Application. I use this

private void btnExportActionPerformed(java.awt.event.ActionEvent evt) {
        try {
            JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("reportRecharge.jasper"), params, new JREmptyDataSource());
            JasperViewer jv = new JasperViewer(printer);
            jv.setVisible(true);
        } catch (JRException ex) {
            ex.printStackTrace();
        }
}

When a JasperViewer appear and I close it, the main frame / parent also closed. I've try adding jv.setDefaultCloseOperation(HIDE_ON_CLOSE); but it's not working either. How to get it?

Any help would be appreciated.

change like below. if you add false the default exit on close property becomes false.

private void btnExportActionPerformed(java.awt.event.ActionEvent evt) {
        try {
            JasperPrint printer = JasperFillManager.fillReport(getClass().getResourceAsStream("reportRecharge.jasper"), params, new JREmptyDataSource());
            JasperViewer jv = new JasperViewer(printer,false);
            jv.setVisible(true);
        } catch (JRException ex) {
            ex.printStackTrace();
        }
}
