you should use CrystalReport 10 or above for Java Reporting that adaptive for java and some approach of your problem  is:

here's the code  that sets the display mode

GraphicsDevice dev = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice(); 
GraphicsConfiguration gc = dev.getDefaultConfiguration();
DisplayMode mode = new DisplayMode(800, 600, 32, DisplayMode.REFRESH_RATE_UNKNOWN);
JFrame frame  = new JFrame(gc); 
frame.setUndecorated(true); 
frame.setIgnoreRepaint(true);

frame.getContentPane().add(new MainPanel(), BorderLayout.CENTER);

frame.show();
dev.setFullScreenWindow(frame); 
if(dev.isDisplayChangeSupported()) dev.setDisplayMode(mode); 

another way is :
adaptive your frame  with screen resolution.

    private Dimension dim;

    private void resolutionAdapter() {

        dim = Toolkit.getDefaultToolkit().getScreenSize();
        screenWidth = (int) dim.getWidth() - 200;
        screenHeight = (int) dim.getHeight() - 200;
    }
