hiya I was wondering if any one could possibly help me....Im quite new to servlets so all the help I can get will be much appreciated.
currently I have a HMTL form that has a drop down list that a user can choose a value from. now how does a servlet read in that value the user chooses?
Many thanks

A servlet can get any form data the user has entered via the following:
String paramValue = request.getParameter("fieldName");
If the field has multiple values (e.g. checkboxes with the same name where multiple values may be checked), you would use the following:
String[] paramValues = request.getParameterValues("fieldName");
hiya i did as you said however i an not picking up what the user chooses.
in this program ive written i want the user to choose a value from the drop down list and then in the servlet i want the user to just print what the user selected. plz help as i dont know what im doing wrong!!!!!!!!!

<option value="Cheese">Old Cheese</option>
<option value="Bread">Hot Bread</option>
</select>
<CENTER><INPUT TYPE="SUBMIT"></CENTER>

import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class ThreeParams extends HttpServlet {
public void doGet(HttpServletRequest request,
HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String docType =
"<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0 " +
