How to make java Module JAR execute by clicking

Question

I am using OpenJDK 11 and OpenJFX 11 on Windows 7. My IDE is Netbeans 9. I have replicated the tutorial (published by NetbeansVideos) below :

JDK 11, OpenJFX, Apache Ant, and Apache NetBeans 10

It is a simple Hello World type code. It works in Netbeans. But when I click the JAR file it doesn't work.

My JAVA_HOME in environment variable is set.

How do I make that Module JAR execute by clicking?

Thanks.

Answer 1

An archive becomes a modular JAR when you include a module descriptor, module-info.class, in the root of the given directories or in the root of the .jar archive.

If you get your OpenJDK binaries from Adoptium, their installer has an option to associate .jar files. (Not sure about other distros) When you have the file association setup double clicking on a modular, executable, jar file behaves as expected. (Confirmed this is working as of JDK 17 and Windows 10). If not, you can manually setup the Windows file association yourself as described in: Running JAR file on Windows
