Get parameter from a POST

Question

Having a problem with a servlet posting from a form:

// index.jsp
<FORM ENCTYPE='multipart/form-data' method='POST' action='/test/uploadfile'>
  Your name: <input type="text" uploadername="name" /><br /> 
  <INPUT TYPE='file' NAME='filetoupload'>
  <INPUT TYPE='submit' VALUE='upload'>
</FORM>

// testservlet.java
protected void doPost(HttpServletRequest request, HttpServletResponse response) 
    throws ServletException, IOException 
{
    String name = req.getParameter("uploadername");
    if (name == null || name.length() < 0) {
        // seems to always be empty.
    }
}

So yeah the name parameter never seems to be sent. What am I doing wrong?

I dont know a thing about servlets however "name" is an html keyword try changing it to name1. — The_asMan, Mar 17 '11 at 22:38

You want

<input type="text" name="uploadername" />

It would seem that what you're trying to do isn't support by the servlet API prior to version 3.0. See this question for details and possible solutions.

This is entirely wrong and getting a form parameter is possible if you change the input element as I describe below. In the servlet req.getParameter should be request.getParameter. – digitalsanctum Mar 18 '11 at 14:00
