Answer 1

i've got an error!
Cannot forward after response has been committed!
    try {
                    downloadFile (((HttpServletResponse)FacesContext.getCurrentInstance().getExternalContext().getResponse()),new File(path));
                    getFacesContext().getCurrentInstance().responseComplete();
                } catch (IOException ex) {
                    ex.printStackTrace();
                }and the download-method:
    public static void downloadFile(
        HttpServletResponse response, File file)
            throws IOException
        BufferedInputStream input = null;
        BufferedOutputStream output = null;
        try {
            // Wrap the file in a BufferedInputStream and pass it through another method.
            input = new BufferedInputStream(new FileInputStream(file));
         //   downloadFile(response, input, file.getName(), attachment);
            int contentLength = input.available();
            String contentType = URLConnection.guessContentTypeFromName(file.getName());
            response.setContentLength(contentLength);
            response.setContentType(contentType);
            response.setHeader(
                "Content-disposition", "attachment" + "; filename=\"" + file.getName() + "\"");
            output = new BufferedOutputStream(response.getOutputStream());
            // Write file contents to response.
            while (contentLength-- > 0) {
                output.write(input.read());
            output.flush();
        } catch (IOException e) {
            throw e;
        } finally {
            if (input != null) {
                try {
                    input.close();
                } catch (IOException e) {
                    e.printStackTrace();
             if (output != null) {
                try {
                    output.close();
                } catch (IOException e) {
                    e.printStackTrace();
    }
