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：

I'm using Synthetica Look and Feel in my application and it works fine on Eclipse. But when i export the Jar file and execute it i got these errors :

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：

I don't know where is the problem exactly. Here is the way I'm applying the Synthetica Blue Steel Look And Feel :

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

    } 
    catch (Exception e) {}

推荐答案

我认为导出jar文件的方式不正确。

I think the way you are exporting the jar file is not correct.

尝试将jar导出为Runnable jar文件。 >
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-> Runnable JAR文件< br>
3）选择启动配置，即主类。

4）如果要将物质库文件打包在自己的jar中，可以选择两个库处理选项（第二个选项）如果要将生成的jar文件和物质库分开，请将所需的库复制到生成的jar旁边的子文件夹中。

5）按完成。

Try exporting the jar as a Runnable jar file.
Follow these steps to export your app as a runnable jar.
1) select export from the file menu.
2) select Java->Runnable JAR file
3) Select the launch configuration i.e your main class.
4) first two option of library handling if you want to package the substance library file in your own jar and the third option(copy required library into a sub folder next to the generated jar) if you want to separate the generated jar file and substance libs.
5)Press finish.

我希望这能解决你的问题。 ：）

I hope this would solve your problem. :)
