I am using Servlet. And request.getParameter() always returns null value even if the radio buttons are checked. Can anyone help?

This is my index.jsp page

<html>
<body>
<form action="FileLoader" method="post" enctype="multipart/form-data">
<p>
<label>
<input type="radio" name="se" value="pre-signing" checked = "checked">
Pre-signing </label>
<br>
<label>
<input type="radio" name="se" value="post-signing">
Post-signing </label>
</p>
</body>
</html>

This my servlet page

public void doPost(HttpServletRequest request,HttpServletResponse response)throws  ServletException, java.io.IOException {
String radioButton= request.getParameter("se");
System.out.println("radioButton ::"+radioButton);}

It returns me a null value even if the radio buttons are checked.
