What about a gnutella2 client written in Java ?
 

I'm trying to find a gnutella2 client written in Java. I want the source code, so that I can make some changes and try something for a research project I have. Do you recommend me any?
Thanks

Hey,

This forum isn't made for the protocol of Mike Stokes, G2. If you want more help, go to http://forums.shareaza.com , the main client of G2.

There isn't a current program written for G2 in Java. Only C++ is the language currently used.

But if you're interested in the original Gnutella, you can find some Java clients in here.

I'd recommend Phex (Phex - Home), since I know that the developer gladly helps other developers, and that changes you share back have a very high chance to get into the main client, so you can really make a difference.

Additionally the source feels cleaner to me than that of LimeWire (but that could be only me), and Phex isn't controlled by a company.

Besides: Gnutella2 is no successor of Gnutella. It is a different protocol which was given that name for marketing reasons (and it's design has similarities), and the first programmer of it (Mike) said a few years ago that he began to see it as mistake that he chose that name.

Besides, again: You can find information about the inner workings of Gnutella at two places:
- Gnutella for Users: The concepts in easily understandeable language: Main Page - Gnufu
- The Specification: Gnutella Protocol Specification - Gnutella Specification

Good luck with your research!
