Read file with nio and flush with servlet

Question

Can I read file, by using java.nio (for example by FileInputStream.getChannel()) and then flush the file content thru the servlet?
I kwow about reading without java.nio, get a byte array and then flush it by httpservletresponse writer or outputstream, but I wish to know if it is possibile with java.nio reading.
thanks

I'm doing it only for file reading..
protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
        response.setContentType("text/html;charset=UTF-8");
        PrintWriter out = response.getWriter();    
        FileInputStream fis = null;                               
        try
            String path = "/var/hello.txt";
            fis = new FileInputStream(path);       
            FileChannel channel =  fis.getChannel();
            ByteBuffer bb = ByteBuffer.allocate((int) channel.size());
            channel.read(bb);
            byte[] data2 = bb.array();
            channel.close();
            out.write(new String(data2));
        } catch (FileNotFoundException ex)
            ex.printStackTrace();
        } finally
            try
                fis.close();
            } catch (IOException ex)
ex.printStackTrace();
            out.close();
    }
