Java Swing：無法從應用程序包創建資源。使用基於Java的資源

我試圖改變Look&FeelJava Swing：無法從應用程序包創建資源。使用基於Java的資源

public class Main { 
    public static void main(String[] args) { 
     try { 
      String osName = System.getProperty("os.name"); 
      if (osName.contains("Mac")) { 
       System.setProperty("apple.laf.useScreenMenuBar", "true"); 
      } 
      UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); 
     } catch (Exception e1) { 
     } 
    } 
}

但得到線UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName())

java.lang.NullPointerException

    at javax.swing.UIManager.setLookAndFeel(UIManager.java:564) 
    at org.camobap.osx.Main.main(Main.java:26)

例外誰能HEPL我避免這個問題？

[按照蘋果（http://developer.apple.com/library/mac/#documentation/Java/參考/ Java_PropertiesRef/Articles/JavaSystemProperties.html）：*當在你的應用程序中設置一個屬性時（使用System.setProperty），確保它是你的main方法中的第一個語句之一。這樣做會在AWT加載之前設置屬性，以確保其生效。*也許嘗試在不檢查操作系統的情況下設置該屬性並查看它是否可用 –

哪種語言在Mac上的語言和文本系統首選項的頂部位置？這似乎是你有一些問題與MAC資源包 –

運行良好在我的Mac與JDK1.7 – Robin

它看起來像你的錯誤是從你的setLookAndFeel線的到來。您應該確認UIManager.getSystemLookAndFeelClassName()正在返回您的想法。你也可以檢查其外觀和感覺都安裝了這個系統下面的代碼上：

try { 
     for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) { 
      System.out.println(info.getName() + " - " + info.getClassName()); 
      //You can now set the look to the one you want with something like this: 
      if ("Mac".equals(info.getName())) { 
       UIManager.setLookAndFeel(info.getClassName()); 
      } 
     } 
    } catch (Exception e) { 
     // Forget the look and feel!   
    }
