Question

我创建了一个Java应用程序并将其导出到.jar文件中。当我在NetBeans上的计算机上运行它时，它可以完美地显示所需的输出和消息。

然而，我的朋友在她的电脑上执行了它，但没有工作。我使用Launch4j将其转换为.exe，但应用程序仍然无法正常工作。

我使用了Jasypt库并将所有.jar文件导入到项目中。每当我运行它。 Launch4j抛出这些错误：

有谁能告诉我发生了什么？

Answer 1

我想到两件事：

你的朋友Java在他的电脑上吗？（运行时库）
如果您的jar文件适用于您的操作系统，请尝试在您朋友的操作系统上使用Launch4j，以便在您的jar文件中使用.exe。

Answer 2

您应创建一个包含所有必需jar（库）的主jars文件，然后您可以使用Launch4j生成exe文件。

看看Launch4J - how to attach dependent jars to generated exe

应用程序（.jar）错误 - NoClassDefFoundError
