Jasper Viewer set title

Question

Here is how I show the Jasper report in swing applications.

 JasperViewer.viewReport(jasperPrint, true);

Then when the report is viewed, the report viewer's title is "Jasper Viewer" . I want to change it and set my own title name. My other question is how to directly send the report to the print without viewing.Please give any sample code.Thank you

Answer 1

What I normally do is :

        JasperViewer jv = new JasperViewer(jasperPrint, false);
        jv.setTitle("Report-Title");
        jv.setVisible(true);

This works because, JasperViewer is a JFrame -

public class JasperViewer extends JFrame{
   //...
}

Answer 2

JasperViewer.viewReport(...)is a wrapper class that creates and shows a JasperViewer JFrame with a JRViewer panel.

Using this method you can't access the underlying JFrame, so you can't change the frame title.

You can try to create your own JasperViewer frame using the public constructor, and then set the title using the setTitle(...) method.

Another and recommended approach is to create a custom JDialog with a JRViewer panel.

To print your report without viewing:

final JRPrintServiceExporter exporter = new JRPrintServiceExporter();
exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);
exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PAGE_DIALOG, Boolean.FALSE);
exporter.setParameter(JRPrintServiceExporterParameter.DISPLAY_PRINT_DIALOG, Boolean.TRUE);
exporter.exportReport();
