Problem with JSF and webcam

[Rafael Rque]

Hi all,

I have this class which is responsible for rendering a frame in my application:

public class SwingCapture extends Panel implements ActionListener{

	private static final long serialVersionUID = 1L;

	public static Player player = null;
	public CaptureDeviceInfo di = null;
	public MediaLocator ml = null;
	public JButton capture = null;
	public Buffer buf = null;
	public Image img = null;
	public VideoFormat vf = null;
	public BufferToImage btoi = null;
	public ImagePanel imgpanel = null;
	public Visitante visitante;
	public String backup,servidor;
	
	
	public String getBackup() {
		return backup;
	}

	public void setBackup(String backup) {
		this.backup = backup;
	}

	public String getServidor() {
		return servidor;
	}

	public void setServidor(String servidor) {
		this.servidor = servidor;
	}
	
	public Visitante getVisitante() {
		return visitante;
	}

	public void setVisitante(Visitante visitante) {
		this.visitante = visitante;
	}

	public SwingCapture(){
		setLayout(new BorderLayout());
		setSize(600,480);
		imgpanel = new ImagePanel();
		capture = new JButton("Capture");
		capture.addActionListener(this);
		//String str1 = "vfw:Logitech USB Video Camera:0";
		//String str2 = "vfw:Microsoft WDM Image Capture (Win32):0";

		di = CaptureDeviceManager.getDevice("vfw://0");  
		ml = new MediaLocator("vfw://0");  

		try
		{
			player = Manager.createRealizedPlayer(ml);
			player.start();
			Component comp;
			if ((comp = player.getVisualComponent()) != null)
			{
				add(comp,BorderLayout.CENTER);
			}
			add(capture,BorderLayout.CENTER);
			add(imgpanel,BorderLayout.SOUTH);
		}
		catch (Exception e)
		{
			e.printStackTrace();
		}
	}

	//	public static void main(String[] args)
	//	{
	//		Frame f = new Frame("SwingCapture");
	//		SwingCapture cf = new SwingCapture();
	//		f.addWindowListener(new WindowAdapter() {
	//			public void windowClosing(WindowEvent e) {
	//				playerclose();
	//				System.exit(0);}});
	//		f.add("Center",cf);
	//		f.pack();
	//		f.setSize(new Dimension(600,480));
	//		f.setVisible(true);
	//	}

	public static void playerclose(Frame f)
	{
		f.setVisible(false);
		f.dispose();
		player.close();
		player.deallocate();
	}

	public void actionPerformed(ActionEvent e)
	{
		JComponent c = (JComponent) e.getSource();
		if (c == capture)
		{
			// Grab a frame
			FrameGrabbingControl fgc = (FrameGrabbingControl)
			player.getControl("javax.media.control.FrameGrabbingControl");
			buf = fgc.grabFrame();
			// Convert it to an image
			btoi = new BufferToImage((VideoFormat)buf.getFormat());
			img = btoi.createImage(buf);
			// show the image
			imgpanel.setImage(img);
			// save image
			saveJPG(img,servidor+"\\"+visitante.getDocumento()+".jpg");
		}
	}
	class ImagePanel extends Panel
	{
		public Image myimg = null;
		public ImagePanel()
		{
			setLayout(null);
			setSize(600,480);
		}
		public void setImage(Image img)
		{
			this.myimg = img;
			repaint();
		}
		public void paint(Graphics g)
		{
			if (myimg != null)
			{
				g.drawImage(myimg, 0, 0, this);
			}
		}
	}

	public static void saveJPG(Image img, String s)
	{
		BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_RGB);
		Graphics2D g2 = bi.createGraphics();
		g2.drawImage(img, null, null);
		FileOutputStream out = null;
		try
		{
			out = new FileOutputStream(s);
		}
		catch (java.io.FileNotFoundException io)
		{
			System.out.println("File Not Found");
		}
		JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder(out);
		JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam(bi);
		param.setQuality(0.5f,false);
		encoder.setJPEGEncodeParam(param);
		try
		{
			encoder.encode(bi);
			out.close();
		}
		catch (java.io.IOException io)
		{
			System.out.println("IOException");
		}
	}
}

I use a h:commandButton to fire this frame up.

My problem is this only works in the server machine.For example,if a cliente tries to run this frame,the frame gets executed not in the client machine,but in the server machine.What am I doing wrong?

If you want Java code to execute on a client machine, you have to put it in an applet.
