    Default Runnable JAR won't run when double-clicked.

    I created a program and compiled it to Runnable JAR. I made sure the configuration is the class with the main() method in the project, and made sure I was choosing Runnable JAR.

    After compiling, double clicking the file won't open it.

    Here's the Class with main():

    import javax.swing.*;
    import java.awt.*;
     
    public class Starter extends JFrame {
     
    	public Starter(){
     
    		setSize(500,500);
    		setResizable(false);
    		setTitle("Pong Battle");
    		setDefaultCloseOperation(EXIT_ON_CLOSE);
     
    		Board b = new Board();
    		add(b);
     
    		setVisible(true);
     
    	}
     
    	public static void main(String[]args){
    		Starter starter = new Starter();
    	}
     
    }

    What could be the problem?

    Default Re: Runnable JAR won't run when double-clicked.

    You didn't post an SSCCE so we have no way of knowing.

    Try running the jar from the command line to see the error you're getting.
