public class WebCam {
public static void main(String[] args) {
// TODO Auto-generated method stu
    otro perro=new otro();
    perro.show();
    perro.proceso();
}
}
class otro extends JFrame{
JLabel Imagen;
otro(){
    Imagen=new JLabel();
    Imagen.setBounds(30,40,20,20);
    add(Imagen);
    setBounds(400,400,400,400);
    setLayout( null ); // use a BorderLayou  
    setTitle("Prueba de Camara Web");
}
public void proceso(){
        Manager.setHint( Manager.LIGHTWEIGHT_RENDERER, true );
    try{
        MediaLocator ml = new MediaLocator("vfw://0");
        Player p = (Player) Manager.createRealizedPlayer(ml);

        Component video = p.getVisualComponent();

        video.setBounds(20,30,600,600);
        if ( video != null ){
            // agragar el video al componente
            add( video);
        }


        p.start();
    }catch(Exception e){
        e.printStackTrace();
    }
}
}

When running the above, getting the following exception:

try with this

    package javasewebcam;

    import java.awt.Graphics2D;
    import java.awt.Image;
    import java.awt.image.BufferedImage;
    import java.io.File;

    import javax.media.util.BufferToImage;

    public class CaptureScreenshot
    {
    private static Player player = null;
    private static Image image = null;

    public static void main(String[] args)
    {
        try
        {
            MediaLocator ml = new MediaLocator("vfw://0");
            player = Manager.createRealizedPlayer(ml);
            player.start();
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
            System.exit(0);
        }

        while (image == null)
        {
            FrameGrabbingControl fgc = (FrameGrabbingControl) player.getControl("javax.media.control.FrameGrabbingControl");
            Buffer buf = fgc.grabFrame();

            BufferToImage bi = new BufferToImage((VideoFormat) buf.getFormat());
            image = bi.createImage(buf);

                        System.out.println("image"+image);
                        if(image!=null)
                        //(toBufferedImage(image));
//save image in here 
                        image=null;
                        System.out.println("streaming");
        }

        try
        {
            ImageIO.write(toBufferedImage(image), "png", new File("screenshot.png"));
            System.out.println("Image Saved!");
        }
        catch (Exception ex)
        {
            ex.printStackTrace();
            System.exit(0);
        }

        player.close();
        player.deallocate();
    }


    public static BufferedImage toBufferedImage(Image i)
    {
        BufferedImage bi = new BufferedImage(i.getWidth(null), i.getHeight(null), BufferedImage.TYPE_INT_ARGB);
        Graphics2D g2d = bi.createGraphics();
        g2d.drawImage(i, 0, 0, null);

        return bi;
    }

    }
