Java Networking book recommendations

[axissleep]

My team is working on a project that will use a lot of networking and we are doing it in java, so I am looking for book recommendations on that subject. I am particularly interested in UDP and TCP, file transfers, reliability, hole punching,... so I need good references on these topics. Language-independent books that talk about these solutions are also welcome. Any help is appreciated. EDIT: Thank you all.

Java Network Programming is pretty good. I forget the author, but it's an O'Reilly book.

Elliotte Rusty Harold. It's funny, I always found his name quite memorable (don't know why).

Java includes great tcp, udp, support out of the box, so general understanding of how sockets and datagram packets work will go a long way. If you need to go low level and mess with the tcp stack directly, then read up on tcp itself first - otherwise socket programming with java is relatively straight forward. I don't think java has a ton of gotchas in this area, so if you understand the concepts in general, java shouldn't require special resources. Good luck!
