How to make a virtual robot?

Question

How would you record events that a user does and then replay them back, without needing any special permissions? This is what my code looks like right now... I am trying to find a way to implement a virtual click on any component that will make it work right.
package virtualRobot;
import java.awt.*;
import java.awt.geom.*;
import java.util.*;
import java.awt.event.*;
import javax.swing.event.*;
import javax.swing.*;
public class VirtualRobot implements Runnable
     Image mousePointer;
     Point2D cursorHotSpot;
     Point2D mouseLocation;
     Vector events;
     Component targetComponent;
     boolean running = false;
     public VirtualRobot(Image mousePointer,Point2D cursorHotSpot,Component targetComponent)
          this.mousePointer = mousePointer;
          this.cursorHotSpot = cursorHotSpot;
          this.targetComponent = targetComponent;
          events = new Vector();
     public void addEvent(AWTEvent e)
          events.add(e);
     public void addEvent (EventObject e)
          events.add(e);
     public void run()
          if(running) // lets not allow 2 robots at the same time
               return;
          running = true;
          try{
          long timeDiff = 0;
          for(int i = 0; i < events.size();i++)
               try
                    Thread.sleep(timeDiff);
               catch (InterruptedException e)
                    break;
               if(events.get(i) instanceof MouseEvent)
                    MouseEvent e2 = (MouseEvent)events.get(i);
                    if(events.get(i) instanceof MenuDragMouseEvent)
                         ((AbstractButton)e2.getSource()).doClick();
                    else
                         e2 = new MouseEvent(targetComponent,e2.getID(),System.currentTimeMillis(),
                                             e2.getModifiersEx(),e2.getX(),e2.getY(),
                                             e2.getClickCount(),false,e2.getButton());
                         targetComponent.dispatchEvent(e2);
               else if(events.get(i) instanceof EventObject)
                    if(events.get(i) instanceof MenuEvent)
                         MenuEvent e2 = (MenuEvent)events.get(i);
                         if(e2.getSource() instanceof JMenu)
                              ((JMenu)e2.getSource()).doClick(1000);
                         else
                              ((AbstractButton)e2.getSource()).doClick();     
               if(events.get(i) instanceof MenuEvent || events.get(i+1) instanceof MenuEvent)
                    timeDiff = 0;
               else if(i != events.size()-1)
                    timeDiff = ((MouseEvent)events.get(i+1)).getWhen() - ((MouseEvent)events.get(i)).getWhen();
          catch(ThreadDeath e)
               running = false;
               throw e;
}PS I've not implemented showing the virtual pointer on the screen.

Answer 1

First java.awt.robot requires a permission access; second, its not supported on all systems; third, it defeats the purpose of a virtual robot that controls a virtual pointer and does not control the real mouse.
