I can upload file in Java Web Application, but, if I want to send information and upload file, the system upload file and consider the information as null!

My code:

  1. Servlet:

        protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
    if (request.getParameter("information") == null)
        System.out.println("information is null");
    Helper helper = new Helper();
    String url = "C:\\Users\\.....<private url>";
    DiskFileItemFactory factory = new DiskFileItemFactory();
    factory.setSizeThreshold(1024);
    factory.setRepository(new File(url));
    ServletFileUpload upload = new ServletFileUpload(factory);
    try{
        List<FileItem> partes = upload.parseRequest(request);
        for(FileItem items: partes){
            File file = new File(url,items.getName());
            items.write(file);
        request.getRequestDispatcher("view/upfile/upfile.jsp").forward(request, response);
        return;
        }
    }catch(Exception e){
            request.getSession().setAttribute("error", e.toString() + ": " + url);
            request.getRequestDispatcher("view/excepciones/message.jsp").forward(request, response);
        return;
    }

    }

File JSP:

<html>
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
</head>
<body>
    <h1>Subir el archivo</h1>
    <form action = "<%= request.getContextPath() %>/UpFilesController" method="post" enctype = "multipart/form-data">
        <input type = "file" name = "file"/>
        <input type = "text" name = "information"/>
        <input type = "submit" name = "action4" value = "Subir Archivo"/>
    </form>

</body>

Out of GlassFish Server: information is null
