How can I get the port of session.getRequestURI() in a Java EE @ServerEndpoint

Question

In my Java EE - Eclipse Oxygen environment with tomcat9 the port is always -1(should be 62114)!

@OnOpen
@Encoded
public void onOpen(@PathParam("BenutzerID") Long BenutzerID, @PathParam("Grad") long Kontaktgrad,
        @PathParam("Accesskey") String Accesskey, Session session, EndpointConfig config) {

    this.port = session.getRequestURI().getPort();

If the port is not defined, the getPort() method will return -1. That's the case when the default port is used.

80 is the default port for http and ws URI schemes.
443 is the default port for https and wss URI schemes.

From the RFC 6455, the document that defines the WebSocket protocol:

By default, the WebSocket Protocol uses port 80 for regular WebSocket connections and port 443 for WebSocket connections tunneled over Transport Layer Security (TLS).

I use port 62114 and 62115! – Hans-Martin Goebel May 17 '18 at 20:47
Why do you need to get the port, by the way? – cassiomolin May 17 '18 at 22:07
I must know which of the two ports is used. , – Hans-Martin Goebel May 18 '18 at 17:43
Or can I bind the socket to a special port? – Hans-Martin Goebel May 19 '18 at 20:28
