Question

我在我的应用程序中使用Synthetica Look and Feel，它在Eclipse上运行良好。但是当我导出Jar文件并执行它时，我遇到了这些错误：

我不知道问题究竟在哪里。以下是我使用Synthetica Blue Steel外观的方式：

try 
    {
      UIManager.setLookAndFeel(new SyntheticaBlueSteelLookAndFeel());
      UIManager.put("Synthetica.rootPane.titlePane.title.center", true);
      UIManager.put("Synthetica.translucency4DisabledIcons.enabled", true); 

    } 
    catch (Exception e) {}

Answer 1

请查看错误，找不到sun / swing / plaf / synth / SynthUI 图书馆。在开发模式中您是在eclipse库中包含该jar文件，但是当您创建一个jar文件时，您不会包含Synthui主题jar。将Synthui jar文件放在jar，ext /文件夹中，它可以正常工作

Answer 2

我认为导出jar文件的方式不正确。

尝试将jar导出为Runnable jar文件请按照以下步骤将您的应用程序导出为可运行的jar 1）从文件菜单中选择导出 2）选择Java-＆gt; Runnable JAR文件
3）选择启动配置，即主类 4）如果你想将物质库文件打包在你自己的jar中，那么前两个库处理选项和第三个选项（将所需的库复制到生成的jar旁边的子文件夹中）如果要分离生成的jar文件和物质库。
5）按完成。

我希望这能解决你的问题。：）
