	private File destinationDir;

	public void init(ServletConfig config) throws ServletException {
		super.init(config);

		destinationDir = new File(realPath);
		if (!destinationDir.isDirectory()) {
			throw new ServletException(DESTINATION_DIR_PATH
					+ " is not a directory");
		}

	}

	protected void doPost(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException {

		PrintWriter out = response.getWriter();
		response.setContentType("text/html");

		DiskFileItemFactory fileItemFactory = new DiskFileItemFactory();
		fileItemFactory.setSizeThreshold(1 * 4096 * 4096);
		fileItemFactory.setRepository(tmpDir);

		ServletFileUpload uploadHandler = new ServletFileUpload(fileItemFactory);

		
		try {
			List items = items = uploadHandler.parseRequest(request);
		
			

			Iterator itr = items.iterator();
			while (itr.hasNext()) {
				FileItem item = (FileItem) itr.next();
				if (item.isFormField()) {
					out.println("Nome do campo = " + item.getFieldName()

				}
				}
			} catch (Exception e) {

				e.printStackTrace();
