Posted by Robert Lewis <rr...@gmail.com>.
WSS will work if you enable and configure the HTTPS connector in server.xml.

This part of the configuration is not really wss specific and tomcat site contains a bunch of good docs on how to do this.

Two things to try:

1. Have you tried to connect without using NGINX as a front end proxy?

2. Have you configured your NGINX server appropriately?

See the following for configuring NGINX to act as a websocket proxy:

http://nginx.org/en/docs/http/websocket.html
https://www.nginx.com/blog/websocket-nginx/

Also, see the following:

http://tomcat.apache.org/tomcat-9.0-doc/web-socket-howto.html

and follow the links to look at both the server and client side code.

Please note that I've not done any of this, since I have Tomcat sitting
behind Apache HTTPD 2.2. I have not ported the proxy_wstunnel module
from Apache HTTPD 2.4 to 2.2.

. . . just my two cents
/mde/

Please note that I've not done any of this.



Re: need help with websocket

Posted by Sharat Jagannath <sh...@gmail.com>.
I get a 404 error when I call my server endpoint with wss.
I'm using tomcat 9 which sits behind ngnix. Does that make a difference?
here's how my server.xml looks like-
