Java JAR file execution

[darklink.perry]

Hi everyone,
I have never actually worked with JAR files. This is my first time, and I am having trouble. After much trouble, I finally modified the manifest so it runs. On command prompt anyway. As in, using java -jar example.jar works perfectly fine, but when I double click it, nothing happens. Help?

What operating system and desktop environment are you using? And do other .jar files run when you double click them?

Generally Windows assumes double click == run the .jar with the javaw.exe executable and sets things up to do that. (Although occasionally people find that they need to set the association - it's been discussed here before.)

Linux makes no such assumption. Out-of-the-box, my K desktop regards the jar file as an archive (like a zip file) and a double click opens it for editing.

And because windows tends to use the javaw version to run on a double click you won't see a console.
So if it's a console app then you won't see anything.
