Why does getParameter("uri") returns null ???

Question

Hi !
JAVA can be rather frustrating and I have run of of dukes. How about IOU ?
Unfortunately none of the previous questions in the db shed light on my problem.
I am trying to get at the "uri" and I have the following code fragment :
package com.developer;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.IOException;
import java.io.PrintWriter;
public class proptest extends HttpServlet
  public void doGet( HttpServletRequest req,  HttpServletResponse resp)
    throws ServletException, IOException
    PrintWriter out = resp.getWriter();
    out.println("Parameter Name: " + req.getParameter("uri"));
  public void init() throws ServletException
    // initialie the servlet here. Use ServletConfig object to get
    //    initialization parameters...
    ServletConfig config = getServletConfig();
    // ... more stuff ...
  }

Hi!
In case anyone stumbles upon this in the database, I worked aroung it by using req.getRequestURI().
However I still do not know why getParameter() returns null. It would be useful e.g. if you want to display a list of all request params e.g.:
// stub code follows...
java.util.Enumeration enum = rea.getParameterNames();
while (enum.hasMoreElements())
String name = (String) enum.nextElement();
System.out.println("Parameter "+name + " " + req.getParameter(name))
...For me, nope, all nulls. If it works for you , do tell me.
Also if you look at the "bugs db" there seems to be a number of issues concerning getParameter().
