I'm currently reading through the official Scalatra documentation, particularly the guide on using Scalatra with Atmosphere. That page explains how to use Scalatra and Atmosphere to write a WebSocket based application which responds to incoming messages with outgoing messages.
For the purposes of an application which connects multiple different messaging sources, how would I send outgoing messages from elsewhere in the application?
Possible examples include:
- messages sent as a result of an incoming HTTP request
- periodic messages on a timer
- messages pulled from a queue
- etc.
Some of these messages could potentially target multiple clients.
I'm a bit confused by the official docs on this matter because all the examples happen various incoming message handlers and I'm not sure where to get a reference to the Atmosphere system or where/how I'm allowed to call it.
I Hope someone can clarify.
