How can i get selected value from list.

Hi all,
I want to retrieve selected item from listbox in a jsp page and send it to a servlet. I am not able to get selected value. Can u please tell me how to get selected value.

In servlet i am trying to get the selected value by using getparameter() function, but its not working.

This is the code i hve given in jsp page:

<%@ page language="java" import="java.util.*" contentType="text/html; charset=ISO-8859-1"

    pageEncoding="ISO-8859-1"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<title>Unblock Page</title>

</head><br><br>



<body background ="bluebg1.jpg" text="DarkBlue">



<select name = "urllist" size="1" >

<%Iterator itr;%>

<% List data= (List)request.getAttribute("data");

for (itr=data.iterator(); itr.hasNext(); )

{

        String s=itr.next().toString();

%>

<option value = "<%=s%>" >  <%=s%> </option>

<%}%>

</select>



<form action="./unblock" method="post"><h1 align="center"><input type="submit" value="Unblock" ></h1></form>

<%



String urllist = request.getParameter("urllist");

System.out.println("String in jsp"+urllist);

%>



</body>

</html>

Re: How can i get selected value from list.

Your

<select>

element (and also any other element eg textfields, checkboxes, etc ) should be inside the

<form> </form>

tags, if you want your data to get posted (via GET or POST) to the URL specified in the form's

action

parameter.
From what I see you seem to have no idea how HTML forms work, so I would suggest this tutorial.

And PLEASE use code tags, when you are pasting code. You can read about them here.
This is already your fourth post in roughly 7-8 months and the fact that you still haven't read the rules only shows your ignorance.
