I am using the launch4j maven plugin to generate an .exe for my application.I would like also to embed a bundled JRE.i managed to achieve it with success from my pc which i have java 1.8.0_161 installed. My problem now is that when i try to execute the .exe from a VM machine that has not java installed i took this error

CryptoAlertNews: This application requires a Java Runtime Environment 1.8.0_161

Why does this happen what I am doing wrong? This is what I have in the pom.xml:

You must be aware that Launch4J does NOT embed the JRE, but instead reference it on runtime.

The <path> contents should be a route that points to a JRE when the EXE is executed.

You can distribute your app with a ZIP, and then put a folder jre at the root folder, and your .EXE in the same folder.

Then your ZIP contents would be as following:

|jre (with the contents of the jre uncompressed, including bin directory)
|app.exe

You can find a question similar to yours here: How to bundle a JRE with Launch4j?
