Oh...how stupid of me!
So it was correct what i did. thank you for your help.
And a servlet is the correct way to use websockets in jetty? or is there
another way?

Ok, so far. That is what i use already ;)
But i get a problem with this example, if i use multiple clients
respectively parallel requests/connections .
If two or more clients connect to the server and the server answers, each
client get all answers.
For example:
Client 1 sends "hello"
Client 2 sends "world" (at the same time)
Client 1 gets hello world or world hello
Client 2 gets the same.
I solved the problem by avoiding "private final Set<ChatWebSocket> _members
= new CopyOnWriteArraySet<ChatWebSocket>();" in my Servlet-Class and in my
Server-Class. Where is that good for?!?! I do not understand it.
It's a single room chat: if a client sends a message, all other
clients must receive it.
That's why the example is iterating over the _members in onMessage().
If you want to reply (and not broadcast), just use the Connection
object to reply to the client that sent the message.
