How do I get servlet request headers information?

package org.kodejava.example.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;

import javax.servlet.Servlet;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

 public class ServletRequestHeader extends HttpServlet implements Servlet {
    protected void doGet(HttpServletRequest request, 
            HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter writer = response.getWriter(); 
    		
        Enumeration enumeration = request.getHeaderNames();
        while (enumeration.hasMoreElements()) {
        	//
        	// Get request header name
        	//
            String name = (String) enumeration.nextElement();
            
            //
            // Get request header value
            //
            String value = request.getHeader(name);
            writer.println("Header [" + name + " = " + value + "
"); // // Read request values, for header information that have multiple // values. // Enumeration values = request.getHeaders(name); while (values.hasMoreElements()) { value = (String) values.nextElement(); writer.println("   Header [" + name + " = " + value + "
"); } } writer.close(); } protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // // Do Nothing! // } }
