Jar File not runnable

Question

My jar file with a JavaFX program is not executable. When I call it with java -jar the following error comes:

Error: Main class com.ersatzteillager.Main could not be found or loaded. Cause: java.lang.ClassNotFoundException: com.ersatzteillager.Main

But the class Main is in the JAR. Please help.

It runs perfect when I run it with IntelliJ Idea.

If I change the file extension from .jar to .zip, the folder "ersatzteillager" is located in the folder "com" and in this folder the Main.class file is located.

Output from jar tvf

Thanks in advance.

It may be in the JAR but is it there under the path `com/ersatzteillager/Main.class`? — user207421, Aug 09 '23 at 09:57
Was the package in the .java file set correctly? I.e `package com.ersatzteillager;` — ODDminus1, Aug 09 '23 at 10:37
I *think* you might either have to use `javapackager` or `jlink` and/or `jpackager` to do this. How did you create the jar? — g00se, Aug 09 '23 at 12:06
There is a guide, you can follow, if you wish it work: [Maven Shade JavaFX runtime components are missing](https://stackoverflow.com/questions/52653836/maven-shade-javafx-runtime-components-are-missing) — jewelsea, Aug 09 '23 at 13:45
I don't use Maven - the dependencies are included as library. — l_lessi06, Aug 09 '23 at 14:42
You say your .jar file contains com/ersatzteillager/Main.class. Java says it does not. Consider editing your question and showing us the output of `jar tf myapplication.jar`. — VGR, Aug 09 '23 at 16:04
Note that it says "could not be found *or loaded*". If it can't find the superclass (which presumably is `Application`) then it won't be able to be loaded. So the likely scenario is that it cannot locate the JavaFX libraries. Creating an executable jar for a JavaFX application is not really supported, though it is just about possible; you are encouraged to create an application bundle using jlink and/or jpackage instead. See https://openjfx.io/openjfx-docs/ and link to "Runtime Images". There is a section at the bottom about creating a runnable fat jar. — James_D, Aug 09 '23 at 18:05
“dependencies are included as library.” -> I don’t know how you do that. But whatever the method, it is probably wrong. — jewelsea, Aug 09 '23 at 22:17
@James_D Shouldn´t be the output then `Error: JavaFX runtime components are missing, and are required to run this application` — l_lessi06, Aug 10 '23 at 06:32
in in Main.java a method **public static void main(String [] main)** or is **static** missing? — Maik, Aug 10 '23 at 07:00
@Maik no the main method is as it should be also the static is not missing — l_lessi06, Aug 10 '23 at 07:02
Doesn't look like a `jar tvf` output to me. You have two classes on the same line twice, and there are no sizes or dates. Please paste the *exact* output. Not what you think it should be. Clearly it *isn't* what you think it should be. — user207421, Aug 10 '23 at 07:23
You get “JavaFX runtime components are missing, and are required to run this application” when you have the JavaFX Java components and the native components cannot be found. That is not your problem. You are not just missing JavaFX native components, you are missing *all* JavaFX components. Having JavaFX libraries added in Idea won’t help you when you try to execute code in a jar outside Idea. You need to follow the instructions previously linked by James if you want your app to work. Or you can try using your jar with a JRE that includes JavaFX, like Azul Zulu “JRE FX”. — jewelsea, Aug 10 '23 at 07:40
@user207421 it was a output of `jar tvf` I have deleted the sizes and dates Now there's the unmodified output — l_lessi06, Aug 10 '23 at 08:51
