ActiveMessaging is an attempt to bring the simplicity and elegance of rails development to the world of messaging. Messaging, (or event-driven architecture) is widely used for enterprise integration, with frameworks such as Java's JMS, and products such as ActiveMQ, Tibco, IBM MQSeries, etc.

ActiveMessaging is a generic framework to ease using messaging, but is not tied to any particular messaging system - in fact, it now has support for Stomp, JMS (using StompConnect), WebSphere MQ, and Amazon Simple Queue Service (SQS), with more in development.

Here's a sample of a processor class that handles incoming messages:

class HelloWorldProcessor < ActiveMessaging::Processor

subscribes_to :hello_world

def on_message(message)
puts "received: " + message
end

end
