a good starting point for java sockets?

hello everyone,

i have just started to implement a client-server paradigm for a secure communication channel... do you know of very good starting point of socket programming with java? a url or a book?

i am looking for something that will guide me through the process of a simple client-server to sth more complicated, multiple threads for clients and so on...

anything good to propose?

ps. i am looking for sth for UDP sockets in particular...
