How to run a .jar in mac?

Question

I've written a relatively simple java application. I have JDK on my PC, but I need it to run on a mac for school. The .jar runs perfectly on my PC, but I tested it on my Macintosh (which, BTW, does not have JDK installed).

Why isn't it running on mac? How can I fix this? Is fixing it even possible?

Answer 1

You don't need JDK to run Java based programs. JDK is for development which stands for Java Development Kit .

You need JRE which should be there in Mac.

Try: java -jar Myjar_file.jar

EDIT: According to this article , for Mac OS 10

The Java runtime is no longer installed automatically as part of the OS installation.

Then, you need to install JRE to your machine.

Answer 2

Make Executable your jar and after that double click on it on Mac OS then it works successfully.

sudo chmod +x filename.jar

Try this, I hope this works.
