I want to pass value to servlet but I keep get null value.

<jsp:useBean id="Helper" class="model.Registration" scope="request"/>
<form action="/Project/Registration" method="post" enctype="multipart/form-data">
    <input type="text" size="20" name="name" value="<%=Helper.getName()%>">
    <input type="submit">
</form>

protected void doPost(HttpServletRequest request,
        HttpServletResponse response) throws ServletException, IOException {
    Registrationh2 = (Registration) request.getAttribute("Helper");
    if(h2!=null){
       System. out.println(h2.getName());
    }
    else
        System. out.println("NULL");        
}

Is there anything wrong with my code?
