将jar转换为exe launch4j后发生JNI错误 [英] JNI error occurred after converting jar to exe launch4j

问题描述

我创建了JavaFX应用程序的JAR文件. JAR文件运行正常，没有任何错误.但是，当我使用launch4j将jar转换为exe并尝试打开exe文件时，出现了两个错误:

I created JAR file of my JavaFX application. JAR file is working perfectly fine without any error. But when i converted jar into exe using launch4j and tried to open exe file file it gives two errors:

Java虚拟机启动器 错误:发生了JNI错误，请检查您的安装并重试.

Java Virtual Machine Launcher Error: A JNI error has occurred, please check your installation and try again.

Java虚拟机启动器 发生了Java异常.

Java Virtual Machine Launcher A Java Exception has occurred.

这是日志:

有人可以帮我吗?

推荐答案

实际上，我在转换为exe时在launch4j中选择了另一个JRE版本.现在，我在开发应用程序时附加了已安装在系统上的JRE，它运行正常.

Actually i was selecting another version of JRE in launch4j while converting to exe. Now i attached the JRE which was installed on my system while developing the application and it's working perfectly fine.
