public class ServletCodigoBarras extends javax.servlet.http.HttpServlet{

   public void doGet(HttpServletRequest request, HttpServletResponseresponse) throws ServletException, IOException {

      ServletOutputStream out = response.getOutputStream();

      ByteArrayOutputStream jpegStream = new ByteArrayOutputStream();

      try {
         BufferedImage barras = //gerar imagem
         JPEBImageEncoder jpegEncoder = JPEBCodec.createJPEGEncoder(jpegStream);
         jpegEncoder.encode(barras);
      }catch (Exception e) {         
         return;
      }
      byte[] jpegBytes = jpegStream.toByteArray();
      response.setHeader("Cache-Control", "no-store");
      response.setHeader("Pragma", "no-cache");
      response.setDateHeader("Expires", 0);
      response.setContentType("image/jpeg");
      out.write(jpegBytes);
      out.flush();
      out.close();
