使用Java RunnableJar更改遠程會話的屏幕分辨率

更改當前系統的屏幕分辨率正常，但我需要更改遠程會話的屏幕分辨率（可能位於virtualbox中）。這是連接和通過程序我需要改變它。形成基於web的應用程序，我將通過提供參數來調用runnable jar文件。使用Java RunnableJar更改遠程會話的屏幕分辨率

public static void main(String[] args) throws InterruptedException, IOException { 
    screenResolution(Integer.parseInt(args[0]), Integer.parseInt(args[1]), Integer.parseInt(args[2]), Integer.parseInt(args[3])); // Screen Resolution of Remote Session. 
} 

public static void screenResolution(int width, int height, int bitDepth, int refreshRate) throws InterruptedException{ 
    java.awt.GraphicsDevice graphicsDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice(); 
    java.awt.DisplayMode change_Mode = new DisplayMode(width, height, bitDepth, refreshRate);//DisplayMode.REFRESH_RATE_UNKNOWN); 
    DisplayMode[] supportedResolutions = graphicsDevice.getDisplayModes(); 
    System.out.println(supportedResolutions.length); 
    for (DisplayMode resolution : supportedResolutions) { 
     System.out.format("%d by %d, (%dbit), %d Hertz \n", resolution.getWidth(), resolution.getHeight(), resolution.getBitDepth(), resolution.getRefreshRate()); 
     if (resolution.equals(change_Mode)) { 
      System.out.format("supported = %s\n",resolution); 
      DisplayMode current_displayMode = graphicsDevice.getDisplayMode(); 
      if (change_Mode.equals(current_displayMode)) 
       System.out.println("=== No need to change Resolution ==="); 
      else { 
       java.awt.GraphicsConfiguration graphConfig = graphicsDevice.getDefaultConfiguration(); 
       javax.swing.JFrame frame = new JFrame("",graphConfig); 
       setResolution(graphicsDevice, frame, change_Mode); 
      } 
      break; 
     } 
    } 
} 
public static void setResolution(GraphicsDevice graphicsDevice, JFrame frame, DisplayMode displayMode) throws InterruptedException{ 
    try { 
     graphicsDevice.setFullScreenWindow(frame); 
     graphicsDevice.setDisplayMode(displayMode); 
     frame.dispatchEvent(new WindowEvent(frame, WindowEvent.WINDOW_CLOSING)); 

     java.awt.Dimension screenSize = java.awt.Toolkit.getDefaultToolkit().getScreenSize(); 
     System.out.println("After Cahange Resolution : "+screenSize.getWidth()+" * "+screenSize.getHeight()); 

     // doing other work...... 
     Thread.sleep(1*60*1000); // min sec millisec 
    }catch(IllegalArgumentException e){ 
     e.printStackTrace(); 
    }finally{ 
     frame.dispose(); //program terminates. screen resolution changes to previous resolution. 
    } 
}

運行我的jar文件在當前機器從控制檯D:\JarLocation>java -jar ChangeResolution.jar 1366 768 32 60它工作正常。但我需要改變屏幕的分辨率，當客戶端有什麼不同的分辨率來測試他的senario。

我在遠程計算機上運行同一個jar文件，但它不能更改。

即使mannually我也不能改變它。它說的顯示設置不能改變。

RDP -

capthNode爲yash.rdp►someip.rdp

通過連接這樣的客戶端/我們的Java程序連接到遠程計算機的管理會話可以改變'DISPLAY'的外觀
