我已经.exe使用应用程序（NetBeans 7.1.2 JDK7）创建了我的项目的 jar 文件JartoExe。现在对于某些类它工作得很好。但它没有显示特定类的/和之后的 GUI。

我已经包含了所有需要的依赖项。但是在特定类之后 GUI 不会显示。.exe文件有什么问题？我错过了什么吗？

更新 在控制台上，它抛出FileNotFound异常。我的文件在当前项目文件夹中。那么，我需要改变什么？

这是因为 getClass().getResourceAsStream()?

异常详情：

很多时候 jars 没有目录。所以getClass().getResourceAsStream(somefile)应该是getClass().getResourceAsStream("\somefile").
