Setting headers and cookies through portlet

You can use the two phase rendering concept to set both headers and cookies through a portlet, I wanted to try that so i built this TwoPhaseRenderingPortlet.java, you can download the sample code from here

package com.ibm.webspherenotes.jsr286;

import java.io.IOException;

import javax.portlet.GenericPortlet;
import javax.portlet.PortletException;
import javax.portlet.RenderRequest;
import javax.portlet.RenderResponse;
import javax.servlet.http.Cookie;

public class TwoPhaseRenderingPortlet extends GenericPortlet {
 protected void doHeaders(RenderRequest request, RenderResponse response) {
  System.out.println("Entering TwoPhaseRenderingPortlet.doHeaders()");
  
  Cookie c = new Cookie("myCookieName", "myCookieValue");
  c.setPath(request.getContextPath());
  response.addProperty(c);
  
  response.setProperty("myHeaderName", "myHeaderValue");
  
  System.out.println("Exiting TwoPhaseRenderingPortlet.doHeaders()");
 }

 protected void doView(RenderRequest request, RenderResponse response)
   throws PortletException, IOException {
  System.out.println("Entering TwoPhaseRenderingPortlet.doView()");
  response.setContentType("text/html");
  response.getWriter().println("Hello from two phase rendering portlet");
  System.out.println("Exiting TwoPhaseRenderingPortlet.doView()");
 }
}

The Response.setProperty() method is used for setting header and you can use it even for setting cookie. But for setting cookie there is specialized Response.setProperty() method that takes cookie object
