We're evaluating Heroku for our java webapp. We read there's a limitation on incoming socket communication:
Heroku, flask, and python sockets?
Does that mean my webapp cannot register for JMS Topics (publish/subscribe pattern)? AFAIK JMS listeners work by listenning on a port (in addition to the HTTP port that is used for serving HTML resources).
And if so, how did them make it work on the Heroku "Pusher" addon?
Thanks very much.
