Hi,

I've compiled the below code without errors.

<code>
import java.awt.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;

public class ScreenShot {

    static void main(String[] args) {
        try
        {
            //Get the screen size
           Dimension screenSize =
Toolkit.getDefaultToolkit().getScreenSize();
            Rectangle rectangle = new Rectangle(0, 0, screenSize.width,
screenSize.height);
           Robot robot = new Robot();
            BufferedImage image = robot.createScreenCapture(rectangle);
            File file;

           //Save the screenshot as a png
            file = new File("screen.png");
            ImageIO.write(image, "png", file);

        }
        catch (Exception e)
        {
            System.out.println(e.getMessage());
        }
    }
}
<code>

The code is from
http://www.codebeach.com/tutorials/screenshots-java.asp

The code grabs the entire screen, but I thought that if I changed the
screenSize reference, I could attempt to retrieve the active window.

I am using the Eclipse IDE and I have set the classpath to the default
package. In that package is the above Java class.

I attempt to run the app but I am getting this error msg.

"java.lang.NoClassDefFoundError:"

Now, I have googled, and the info I get is that the JVM cannot see the
class. But I cannot see why if I have set the classpath.

Thanks for you help
