title: How to create a Runnable Jar File on Mac with Eclipse
body: <p>I am currently trying to turn my Java project into a Jar file but I have run  into a problem. When exporting the project, I am forced to add a .zip extension to my file to export it. When I unzip the file, I am left with a fileName.jar file but it is a folder. Shouldn't it be a file that I can double click and open? Or is that only on Windows?</p>
