Welcome to the Ranch.

I noted that Jasper's JRViewer extends swing's JPanel so the viewer is a (swing) component. So adding the JRViewer to the JDesktopPane should be valid.

Does the report itself compile? Does the DB connection chit1.conn null (for the JasperPrint)?

I noticed your report path has a space in it, this might be the problem.

I got the step to display jasper Report

Create Jinternal Frame add below code and then add to JdesktopPane
here is the code

private void Report() 
 {
          
     try 
       {
               Connection dataSource = chit1.conn; 
                JasperDesign jd=JRXmlLoader.load("F:\\Net Beans\\Project\\Chit\\src\\Report\\report1.jrxml");
                JasperReport report=JasperCompileManager.compileReport(jd);  
                JasperPrint jasperPrint = JasperFillManager.fillReport(report, null, dataSource);
                JRViewer viewer = new JRViewer(jasperPrint);   
                   Container c= getContentPane();
                   c.setLayout(new BorderLayout());
                   c.add(viewer);  
              //  JasperViewer.viewReport(jasperPrint);  //this is for Mainframe Display Seprately
       }
     catch (JRException ex) 
         {
             System.out.println(ex); 
            Logger.getLogger(MemberReport.class.getName()).log(Level.SEVERE, null, ex);
         }
 }

I think you call the Report() method after the JInternalFrame has shown. (That means after calling setVisible(true))
If you have done that you have to re-validate your JInternalFrame. To do that type revalidate() after adding the viewer.

If you don't know why revalidate() should be called, search google or read API.
