Answer 1

Also if you want not to pass login/password to server (as you might rely on Spring security) then you shouldn't use

stompClient.connect('', '', function(frame) {

but instead

stompClient.connect({}, function(frame) {

Take a look here: https://github.com/spring-guides/gs-messaging-stomp-websocket/issues/10

Answer 2

The mistake was wrong controller mapping. I have:

  @MessageMapping("/hello")
    @SendTo("/topic/greetings")
    public Greeting greeting(HelloMessage message) throws Exception

and in the jsp:

stompClient.subscribe("<c:url value='/topic/greetings'/>", function(greeting){...

and

stompClient.send("<c:url value='/app/hello'/>", {}, JSON.stringify({ 'name': name }));

The right ones are:

stompClient.subscribe('/topic/greetings', function(greeting){...
stompClient.send('/app/hello', {}, JSON.stringify({ 'name': name }));

The c:url adds the root of the project, when I removed it the app worked. However c:url(the root) is rquired when create new socket with SockJs here:

var socket = new SockJS("<c:url value='/hello'/>");
