Hi All,
I am trying to make websocket connection using html and javascript.
My client is as follows:
const socketUrl = "ws://host:port/example";
const socket = new WebSocket(socketUrl);[
And I have Servlet as follows
@WebServlet(name = "WebSocket Servlet", urlPatterns = { "/example" })
public class MyWSServlet extends JettyWebSocketServlet
{
@Override
public void configure(JettyWebSocketServletFactory factory) {
factory.setIdleTimeout(Duration.ofSeconds(1000));
factory.register(MySocket.class);
factory.addMapping("/", (req,res)->new MySocket());
}
}
@WebSocket
public class MySocket{
@OnWebSocketConnect
public void onConnect(Session session) {
System.out.println("Connect: " + session.getRemoteAddress());
}
}
I am using websocket-jetty-server dependency in pom.xml
When I try to hit the ws api, at server side I see that in upgradeRequest()
validateNegotiation returns false and hence request is not upgraded to
websocket.
As per chat gpt negotiateHeaders() is responsible to add Upgrade:websocket in
request headers. But I do not see that happening in jetty.
I have attached stack trace for reference. Can someone please help me with this
problem to establish a websocket connection using jetty?
The message that I see in browser console is "connection to
'ws://host:port/example' failed:"
Thanks,
Yash Sharma
