Unable to run jar file on command prompt

I'm trying to run a program I've made in eclipse. Have exported it as a runnable jar file, and saved it on the desktop, but when I try to run it from the command prompt it says : "Error: Unable to access jarfile Matador.jar"

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;

public class Password implements ActionListener {
private String Username = "hudhud";
private String Password = "fitness";
private JTextField txtUsername;
private JTextField txtPassword;

public static void main(String[] args){
    Password gui = new Password();
    gui.go();
}
public void go(){
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    JPanel panel = new JPanel();
    JLabel lblUsername = new JLabel("Username:");   
    JLabel lblPassword = new JLabel("Password:");
    txtUsername = new JTextField(20);
    txtPassword = new JTextField(20);
    JButton btnLogin = new JButton("Login");
    btnLogin.addActionListener(this);
    JButton btnCancel = new JButton("Cancel");
    btnCancel.addActionListener(this);


    panel.add(lblUsername);
    panel.add(txtUsername);
    panel.add(lblPassword);
    panel.add(txtPassword);        
    panel.add(btnLogin);
    panel.add(btnCancel);
    frame.getContentPane().add(BorderLayout.CENTER,panel);



    frame.setSize(300,300);
    frame.setVisible(true);


}
@Override
public void actionPerformed(ActionEvent e) {
    String cmd = e.getActionCommand();
    String msg;
    if (cmd.equals("Login")) {
        if (txtUsername.getText().equals(Username) && txtPassword.getText().equals(Password)) {
            msg = "Welcome";
        } else {
            msg = "Login denied. The username or password is incorrect";
        }
    } else {
        msg = "Where are you going, couldn't you guess the password and username??";
    }
    JOptionPane.showMessageDialog(null, msg);
}

}

Project structure:

c:\project\Matador.jar

  1. Start command prompt,
  2. cd c:\project
  3. java -jar Matador.jar

That error means, that the jar file couldn't be found. You have to specify the path to your jar like that:

java -jar path/To/Your/Jar/Matador.jar

Do this:

java -jar <jar-file-name>.jar

Just make sure you are in the right directory.
