Getting cookies from a webpage

[Connor]

Off this website(docs.oracle.com/...) I found the code to get cookies from a webpage:

String retrieveCookie(URL url)
{
     String cookieValue = null;

     CookieHandler handler = CookieHandler.getDefault();
     if (handler != null)    {
          Map<String, List<String>> headers = handler.get(url.toURI(), new HashMap<String,                                                           List<String>>());
          List<String> values = headers.get("Cookie");
          for (Iterator<String> iter=values.iterator(); iter.hasNext();) {
               String v = iter.next();

               if (cookieValue == null)
                    cookieValue = v;
               else
                    cookieValue = cookieValue + ";" + v;
          }
     }
     return cookieValue;
}

I pasted it in eclipse to see how it works but it gave me numerous errors. So I changed it to this which didn't give me errors other than a dead code warning on the "{cookies = cookies + ";" + v;}" lines. Whenever I run it though I just get a return value of null instead of the cookies. Why? When try the same using URLConnection I have no issues. Anyways here's the current code:

import java.io.IOException;
import java.net.CookieHandler;
import java.net.URISyntaxException;
import java.net.URL;
import java.util.HashMap;
import java.util.Iterator;
import java.util.List;
import java.util.Map;


public class Main {

	/**
	 * @param args
	 */
	public static void main(String[] args) throws IOException, URISyntaxException {
		System.out.println(getCookies(new URL("http://www.fridaystudentportal.com/passaicvalley/index.cfm"))); 
	}

	private static String getCookies(URL url) throws IOException, URISyntaxException {
		String cookies = null;
		
		CookieHandler handler = CookieHandler.getDefault();
		if (handler != null) {
			Map<String, List<String>> headers = handler.get(url.toURI(), new HashMap<String, List<String>>());
			List<String> values = headers.get("Cookie");
			
			Iterator<String> iter;
			for (iter = values.iterator(); iter.hasNext();); {
				String v = iter.next();
				
				if (cookies == null) {
					cookies = v;
				} else {
					cookies = cookies + ";" + v;
				}
			}
		}
		
		return cookies;
	}
}

What methods work and what don't? Add some println statements that print out the results of each step so you can see what the code does.
