Instructions for running the CafeDemo AMQP sample

Distributed components

To run this alternative configuration of the sample, be sure to have a RabbitMQ broker started on localhost:5672 configured with the default guest|guest client credentials on the / vHost, then execute the following test classes in order:

1. cafeDemoAppBaristaColdAmqp - starts the Cold Drink Barista
2. cafeDemoAppBaristaHotAmqp - starts the Hot Drink Barista
3. cafeDemoAppAmqp - starts the Cafe Storefront (Places 100 orders on the orders queue)
4. cafeDemoAppOperationsAmqp - starts the Cafe Operations (OrderSplitter, DrinkRouter, PreparedDrinkAggregator)

Note: All AMQP exchanges, queues, and bindings needed for this sample are defined within the different xml config files that support the above test classes.
