Instructions for running the CafeDemo JMS sample

Distributed components

To run this configuration, start an instance of ActiveMQ with the openwire/TCP connector available on the default port (61616). There are no credentials of which to be aware. Please execute the following classes in order:

1. **CafeDemoAppBaristaColdActiveMQ - starts the ColdDrink Barista
2. **CafeDemoAppBaristaHotActiveMQ - starts the HotDrink Barista
3. **CafeDemoAppOperationsActiveMQ - starts the Cafe Operations (order splitter, drink router, etc).
4. **CafeDemoAppAcitveMQ - places the orders

JMS backed components

See CafeDemoActiveMQBackedChannels for an example of how to use the JMS-backed channels. No need to start an external ActiveMQ because one is started internally
