Question

当我使用 getClass（）。getResource（ACCEPT_PNG）加载ImageIcon时，它在我的本地计算上运行良好。当我的类在JAR中嵌入其ressource时，对于Java Web Start应用程序，无法找到ressource，并且相同的代码返回null ...

有什么想法吗？

   /** Path to a PNG ressource. */
   private static final String ACCEPT_PNG = "accept.png";

   private static ImageIcon acceptPngIcon = null;

   private ImageIcon getAcceptPngIcon() {
      if (acceptPngIcon == null) {
         acceptPngIcon = new ImageIcon(getClass().getResource(ACCEPT_PNG));
      }
      return acceptPngIcon;
   }

I had the same issue and solved it by following the approach in Oracle's Java Web Start tutorial: use the class loader to retrieve the resource instead of the class itself:

getClass().getClassLoader().getResource(ACCEPT_PNG); 
    // works both locally and via Web Start
getClass().getResource(ACCEPT_PNG); 
    // only works locally; returns null for any path via Web Start

使用Java Web Start获取getClass（）。getResource（）
