Importing the com.apple.com.dnssd package

I am trying to compile and run the sample bonjour program that apple apple provides in the BonjourSDK found here: http://developer.apple.com/networking/bonjour/index.html

The program is called SimpleChat.java. However, when I try to compile the program, I get this error: "SimpleChat.java:55: package com.apple.dnssd does not exist"

I cannot permanently terminate the necessary file containing this package. I must be missing something simple but can't figure it out. I just installed JDK 1.6 but it didn't help. Thank you for your time.
