Java Development Tools

Dear Gurus,

I have created stand alone ADF application, with Java Desktop Application (ADF) wizard. I have created edit form through wizard and able to run it, My requirement is to run the form/application in full screen mode. 

frame.setsetUndercorated(true) is throwing  java.awt.illegalcomponentstateexception the frame is displayable Exception and frame is getting close. Kindly help me to get out of it. or let me know other approach to achieve my requirement.

    public static void main(String[] args) {
        
//        JFrame frame1 = new JFrame();
////        frame1.setExtendedState(JFrame.MAXIMIZED_BOTH); 
//        frame1.setUndecorated(true);
//        frame1.setVisible(true);
        try {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        } catch (Exception exemp) {
            exemp.printStackTrace();
        }
        try {
            JUMetaObjectManager.setErrorHandler(new JUErrorHandlerDlg());
            JUMetaObjectManager mgr = JUMetaObjectManager.getJUMom();
            mgr.setJClientDefFactory(null);
            BindingContext ctx = new BindingContext();
            ctx.put(DataControlFactory.APP_PARAM_ENV_INFO, new JUEnvInfoProvider());
            ctx.setLocaleContext(new DefLocaleContext(null));
            HashMap map = new HashMap(4);
            map.put(DataControlFactory.APP_PARAMS_BINDING_CONTEXT, ctx);
            mgr.loadCpx("view.DataBindings.cpx", map);
            final EmployeeForm frame = new EmployeeForm();
            
            frame.setBindingContext(ctx);
            frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
            Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
            Dimension frameSize = frame.getSize();
            if (frameSize.height > screenSize.height) {
                frameSize.height = screenSize.height;
            }
            if (frameSize.width > screenSize.width) {
                frameSize.width = screenSize.width;
            }
//            frame.setLocation((screenSize.width - frameSize.width) / 2, (screenSize.height - frameSize.height) / 2);
            frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
            frame.setVisible(true);
         
            
            frame.setUndecorated(true);
        } catch (Exception ex) {
            JUMetaObjectManager.reportException(null, ex, true);
            System.exit(1);
        }
    }
