Where can I find good material on web sockets?

Question

Java

Hello! I'm currently trying to write my chat in Java :) As far as Google has been able to help me, web socket technology is the best for this.
Where can you find it? What to read (preferably in Russian)?
Or maybe some other technology will do?

Answer 1

You will have to start learning everything from the most basic knowledge about sockets, read books and sit constantly on forums where they specialize in this topic.

Answer 2

And why exactly web sockets, sorry? Why don't you go to do it on normal sockets or on nio or netty, for example?
If you really want to, here is an example of a chat just on web sockets, but IMHO, this is a clear overkill.

You can read about the web sockets themselves in Java, for example, in the official tutorial from Oracle.
docs.oracle.com/javaee/7/tutorial/doc/websocket012.htm
Whether there is something in Russian - I'm not sure.
