Subject: class java.lang.Thread & the hamsam.protocol.yahoo.YahooProtocol

I am trying to integrate yahoo messanger features into my program and was directed to this site:

http://hamsam.sourceforge.net/javadoc/hamsam/protocol/yahoo/YahooProtocol.html#YahooProtocol()

It has all the functions in the class that i need, I am just curious where I can find the actual class (VCX file) to add this class to my program so that I may use the fnctions it has, can anyone help me with this?
