Can you require 1.5?

I suppose I can (currently, we allow 1.4.2, since that's the default

current work-around is to tell people to use Safari instead of Camino
or Firefox.

OK, I turned the sample code I posted the url for earlier into a applet, the Fetch class part of it, the url again,

http://java.sun.com/developer/JDCTechTips/2005/tt0913.html

The turned applet class...

import java.io.*;
import java.net.*;
import java.util.*;
import java.applet.Applet;

public class Fetch extends Applet implements Runnable {
String server = "http://www.kikobu.com/appletsession/";;
Thread mainThread;

public void init() {
	String server = getParameter("server");
	if (server != null) this.server = server;
    mainThread = new Thread(this);
    mainThread.start();
}
public void run() {
   try {
	   String urlString = server;
	   CookieHandler.setDefault(new ListCookieHandler());
	   URL url = new URL(urlString);
	   URLConnection connection = url.openConnection();
	   Object obj = connection.getContent();
	   url = new URL(urlString);
	   connection = url.openConnection();
	   obj = connection.getContent();
	   connection = url.openConnection();
	   obj = connection.getContent();
   }
   catch (Exception ex) { ex.printStackTrace(); }
}
}

Note that all the applet class does for cookies is... CookieHandler.setDefault(new ListCookieHandler()); and I added one extra connection for good measure if you look at the tech tip. Signed the jar for the applet to set the CookieHandler and when it runs from Firefox against what was indicated before was, and in fact seemed to be, a problematic URL for Firefox applet session id's ...

The session id appears to be maintained with no effort on the applets part. I have no idea if HTTPS throws in any wrinkles but it seems otherwise if you can require 1.5 this should be a non-issue. 1.6 supposedly actually provides a default cookie handler so life gets even better.

Back to JEP, still curious if I can manage that w/o 1.5.
