Please Help - Secure Internet

Question

On Sun's home page at http://java.sun.com they have an article
on "Secure Internet Programming with JavaTM 2, Standard Edition (J2SETM) 1.4" so I tried it out but I got "cannot resolve symbol" compiler
error when I tried to compile HttpsServer.java - so what do I change
to get it to compile?
Here's the actual error message:
HttpsServer.java:32: cannot resolve symbol
symbol : class ServerSocketFactory
location: class HttpsServer
ServerSocketFactory ssf = sslcontext.getServerSocketFactory();
^

I'm using JDK1.4.1 but I can't believe that is the problem. Here is the
soucre code from the article:

borntwice80, many thanks for your response - good idea
but it turns out that all I needed was the following statement:
import javax.net.*;                                                       
...and that fixed the problem
...Actually, it was mutmansky in the java programming forum
that found it.
