I am using Bitnami's Tomcat AWS AMI which includes Apache httpd as a proxy web server via AJP. I am not sure if I can use WebSocket connections with this stack.
Whenever I start tomcat I see this in the logs:
WebSocket handshake failure; nested exception is java.lang.UnsupportedOperationException: HTTP upgrade is not supported by the AJP protocol
I haven't changed any configuration files. Just deployed my app in webapps folder.
