values of input text fields in a html multipart form

Here's what I am using for this purpose:

    public static Hashtable getParamsFromMultipartForm(HttpServletRequest req) throws FileUploadException {
        Hashtable ret = new Hashtable();
        List items = new ServletFileUpload(new DiskFileItemFactory()).parseRequest(req);
        for (FileItem item : items) {
            if (item.isFormField()) {
                ret.put(item.getFieldName(), item.getString());
            }
        }
        return ret;
    }

And then, whenever i need the value of any of my params, i just write, say:

//at the beginning of a servlet
Hashtable multipartParams = TheClassWhereIPutThatMethod.getParamsFromMultipartForm(req);


String myParamFromForm = multipartParams.get("myParamFromForm");
