How to send message to the @ServerEndpoint from .class

Question

I don't know how to send a message to the @ServerEndpoint. I want to send a message from different project to the project which contains @ServerEndpoint. @ServerEndpoint code below...

@ServerEndpoint("/posluzitelj")
@Stateless
public class Posluzitelj {
    static Queue<Session> queue = new ConcurrentLinkedQueue<>();

    public static void send(String message) {
       
    }

    @OnMessage
    public void onMessage(String message) {

    }

    @OnOpen
    public void openConnection(Session session) {
        queue.add(session);
    }

    @OnClose
    public void closedConnection(Session session) {
        queue.remove(session);
    }

    @OnError
    public void error(Session session, Throwable t) {
        queue.remove(session);
    }
    
}

So, I wanna trigger onMessage function via another project class. How can I do that? Also, I do not want to use javascript! I wanna make communication with java language.
