How do I programatically collect packets from passively sniffing? [closed]

Question
I want to test the vulnerability of the server I just wrote against man in the middle attacks.
How (on Mac OS X) do I analyze packets. (I'll be checking where they are going, pulling information from if they are heading to my server, and seeing what all is available) Then I'll figure out a way to encrypt everything... but first things first.
Any help on packet sniffing would be greatly appreciated.
My preferred language is java. But I can do C++.
so, my question is: "Is there any sort of API / library that I can interface with?"
Like, if I could do PacketSniffer ps = new PacketSniffer(); that would be amazing.
Solution
The best portable library for this is libpcap. There's even a java wrapper available for it.

No need to write your own - Download Wireshark from http://www.wireshark.org/
You should take a look to libcrafter: http://code.google.com/p/libcrafter/
The library has a Sniffer class with an interface very easy to use:
