I have code below for creating the HTTP header:

Code:

import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class ServletTesting extends HttpServlet 
{
private static final long version = 1L;
Public ServletTesting ()
{
super ();
}
protected void doGet (HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
res.setHeader ( "myVar", "thousand");
res.sendRedirect ( "deux.jsp");
System.out.println ("***** get ******");
}
protected void doPost (HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
}
}

As you are telling that you have omitted the code below which you need to add in your program. It will solve your problem.

Code:

<%
response.setHeader ( "DDD", "iiii");
%>

I am having following code of the Header in jsp :

Code:

<%-- set content type and character set --%>

<%@ page contentType="text/html;charset=WINDOWS-1252"%>

<%-- include the JML taglib for use in the JSPs of the application --%>

<%@ taglib uri="-----------------" prefix="-------" %>

<%-- include the HeaderBean and HotelBean --%>
<jsp:useBean id="head" class="HeaderBean" scope="application" />
<jsp:useBean id="hrs" class="HotelBean" scope="session" >
  <%-- Create a Connection object --%>
  <% hrs.dbConnection(); %>
</jsp:useBean>

I am not having great knowledge of java, but as you are not included the code below :

Code:

<%
response.setHeader ( "DDD", "iiii");
%>

You can check whether you are getting the problem by adding it or not. It may possible that your problem would get solved by this and you get the solution. So, just try it and solve the problem.

I have created the code below for displaying the Header "Variable":

Code:

<% @ Page language = "java" contentType = "text / html; charset = ISO-8859-1"
contentType = "ISO-8859-1"%>
<% @ page import = "java.util .*"%>
<% @ page import = "com.sun.net.httpserver.HttpContext"%>
DOCTYPE html 
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title> Insert title here </ title>
</ head>
<body>
<% = request.getHeader ( "variable")%>
<br/>
<%
HeaderName HName = "";
for (Enumeration enum = request.getHeaderNames ();
enum.hasMoreElements ()
{
HeaderName = (HName) enum.nextElement ();
out.println (HeaderName +":"+ request.getHeader
(HeaderName) + "<br/>");
}
%>
</ Body>
</ html>
