Websocket on Tomcat: Unexpected Response Code 200

[awsk1994]

Hi,

I use jRuby and I have the dev environment working fine on Puma server, and websockets work fine. On production, however, the application is deployed on Tomcat using warble. The websocket client gives

Websocket connection to <server_ip:port> failed: Error during WebSocket handshake: unexpected response code: 200

In the server log, I could see the onOpen Being triggered, but the websocket connection is lost.

Can you please help me?

Thanks,
Alex

If you're getting a 200 status, this suggests that this library is not being given direct access to the TCP stream so it can write its own response headers.

We only support servers that implement the rack.hijack API. Does Tomcat support that?

I realize that this is the same issue as jruby/jruby-rack#167

Thank you so much for the help.

Hello @awsk1994, how are you?

Can you use jruby, faye-websocket and warble? I created a war with warble but when I try connect with jetty I receive this message.

var scheme   = "ws://";
var uri = scheme + window.document.location.host;
var ws = new WebSocket(uri);

// WebSocket connection to 'ws://localhost:8080/' failed: Error during WebSocket handshake: Unexpected response code: 500

I think that I need some jetty configurations when I will create a war. But, I don't know how add this configurations. Is it possible?

This is my issue in warbler gem: jruby/warbler#416

Thanks.
