我试图从 jar 文件中制作一个 exe。它做得很好，当我运行它时，它会给出一个像这样的记事本错误文件， （当我在 netbeans(shift+F6) 上运行它时它可以正常工作）

在 exe4j 中，您需要包含应用程序使用的所有依赖项 Jar。当您使用 Netbeans 表单编辑器和它的“默认”布局管理器时，您需要包含它的库 Jar，它不是默认 JRE 的一部分。

exe4j

浏览到您的项目目录并查看该dist\lib目录。您将需要包括其中列出的所有 jar 文件

这是因为您已针对 netbeans jar 编译它，但它们未包含在类路径中。您必须以一种或另一种方式将它们放在课程路径上。您可以在 jar 导出中包含这些库，它们应该会自动显示，或者您可以在启动 exe 时硬编码它们在类路径中的位置（编辑它的启动脚本）。

我推荐第一个选项，因为它使它在您从一个系统到另一个系统时更加便携。
