Answer 1

If the project is under netbeans IDE, you should follow these steps:

Right click on the project and then click on Properties

Click on Packaging

Click on Compress JAR File

Accept changes, click OK

Right click on the project and then click on Clean and Build

Go to the directory where your project is stored

Look in the dist folder for the JAR file

To select the main class that will be executed

Click on Run

Click on Browse near to Main Class label

EDIT :

If you are using netbeans under windows, and if the jar file does not generate any output, try the following command in cmd :

start /b <jar file>

Then an error should appear

So you can know what is the problem
