I'm writing a simple java program with the intent to break an afk limit. Whenever I run it in Eclipse, it works just fine. However, when I export it as a runnable jar file, It won't simulate key presses. I believe I have the correct run configuration and everything which is why I'm so confused. Anyway, here is the main class:

package minebot;
import javax.swing.JOptionPane;

public class MineBotRunner 
{

    public static void main(String[] args) 
    {
        try 
        {
            MineBot bot = new MineBot();

            bot.run();
        } 
        catch (Exception e) 
        {
            e.printStackTrace();

            JOptionPane.showMessageDialog(null, "MineBot encountered an error and will now close.", "MineBot", -1);

            System.exit(0);
        }
    }

}

And here is the other class:

package minebot;

import java.awt.AWTException;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Robot;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;

import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class MineBot implements ActionListener
{
    private JFrame frame;

    private JButton button;

    private String title = "MineBot";

    private boolean isMoving = false;

    private long sysTime;

    private long waitTime;

    private long delay = 780000; //A 13 minute interval between actions to beat the 15 minute AFK limit.

    private int holdDelay = 500; //A .5 second hold time for key presses.

    private int wait = 200; //A .2 second wait time between forward and reverse actions.

    private int forward = KeyEvent.VK_W; //The key held for the first action.

    private int backward = KeyEvent.VK_S; //The key held for the second action.

    private Robot robo;

    public MineBot() 
    {

    }

    private void CreateGUI()
    {
        try 
        {
            robo = new Robot();
        } 
        catch (AWTException e) 
        {
            JOptionPane.showMessageDialog(null, "MineBot encountered an error and will now close.",title, 2);
            System.exit(0);
        }

        frame = new JFrame(title);

        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        frame.setPreferredSize(new Dimension(250,150));

        button = new JButton("Start");

        button.setBackground(Color.RED);

        button.addActionListener(this);

        button.setActionCommand("button");

        frame.add(button);

        frame.pack();

        frame.setLocationRelativeTo(null);

        frame.setVisible(true);

        JOptionPane.showMessageDialog(frame, "<HTML><CENTER>Welcome to MineBot! If you have any ideas<br> for additional features or programs, please<br> email me at <a color=#fff>Zanda268@gmail.com</a>!</CENTER</HTML>",title, -1);
    }

    private void StartMoveLoop() throws InterruptedException
    {
        sysTime = System.currentTimeMillis();

        waitTime = sysTime + delay;

        while(true)
        {
            if(isMoving)
            {
                sysTime = System.currentTimeMillis();

                if(sysTime>waitTime)
                {
                    waitTime = sysTime + delay;

                    robo.keyPress(forward);

                    Thread.sleep(holdDelay);

                    robo.keyRelease(forward);

                    Thread.sleep(wait);

                    robo.keyPress(backward);

                    Thread.sleep(holdDelay);

                    robo.keyRelease(backward);
                }
            }
        }
    }

    public void run() throws InterruptedException
    {
        CreateGUI();

        StartMoveLoop();
    }

    public void actionPerformed(ActionEvent a) 
    {
        if(a.getActionCommand().equals("button"))
        {
            if(isMoving)
            {   
                button.setBackground(Color.RED);

                button.setText("Start");

                isMoving = false;
            }
            else
            {
                button.setBackground(Color.GREEN);

                button.setText("Stop");

                isMoving = true;
            }
        }
    }
}

They GUI will pop up and I can click the button however no key presses are simulated. Any help would be greatly appreciated!

Wow sorry. Eclipse does export those dependancies but like an idiot, I forgot to add my JRE to my build path. And PS @Dileep, you don't 'have' to do it separately.

Eclipse Contains a lot of Jar Files in it and it uses the jars for the execution of the project.

But when you convert that to a runnable Jar. It wont warp all the packages in it. You must add them separately to your project library. Else it cause problems in running the Jar.!! Use Add Build Path to add dependencies. The Java build path is used while compiling a Java project to discover dependent classes and that is how JVM identifies the depended class.

In Large projects you can use Class Dependency Analyzer for finding the dependencies in the project.
