6. What If... Wouldn’t it be great if - I could use the power of Java libraries with the ease of Ruby - I could use the power of a proven Java Server without writing any XML - I could deploy my JRuby app and test it without rebuilding it and restarting the server Monday 26 March 12

Messaging In a long running service - ... def do_something puts "Checking the queue for messages ..." bunny = Bunny.new(:logging => false) # start a communication session with the amqp server bunny.start # declare a queue q = bunny.queue(@name) # get message from the queue msg = q.pop[:payload] puts "This is the message: " + msg.to_s # close the connection bunny.stop end Monday 26 March 12
