Question

I have created this applet, It moves mouse to 1000 pos on screen. It works as application but it does not work in applet. I have created signed applet but still it wont move mouse. What should I do to make my Robot class work from browser? My code is as below:

import java.applet.Applet;
import java.awt.Graphics;
import java.awt.Robot;
import java.awt.AWTException;

public class s extends Applet {
        public void paint(Graphics g) {
            g.drawString("Test1", 10, 10);
        }

        public void init() {
                try {
                        Robot robot = new Robot();
                        robot.mouseMove(1000,50);
                        System.out.println("code executes");
                } catch (Exception ex) {
                        System.out.println("code failed");
                };
        }
}
Was it helpful?

Solution

Signing alone won't give your Applet any permissions. You need to grant the createRobot permission to your Applet.

Check the security tutorials for more details.

OTHER TIPS

I've checked the source-code from Robot. And I think you have to add in the constructor a ScreenDevice.
