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，我收到了这些错误:

不知道问题到底出在哪里。以下是我应用 Synthetica Blue Steel 外观和感觉的方式:
try
{
UIManager.setLookAndFeel(new SyntheticaBlueSteelLookAndFeel());
UIManager.put("Synthetica.rootPane.titlePane.title.center", true);
UIManager.put("Synthetica.translucency4DisabledIcons.enabled", true);
}
catch (Exception e) {}
最佳答案
请查看找不到 sun/swing/plaf/synth/SynthUI 的错误 图书馆。在开发模式下，您可以将该 jar 文件包含在 eclipse 库中，但是当您创建 jar 文件时，您不会包含 Synthui 主题 jar。将 Synthui jar 文件放入 jar、ext/文件夹中，它可以正常工作
