* README FOR PRODUCER / CONSUMER EXAMPLE *
******************************************

The producer / consumer test can be used to show how executions can be saved and restarted after a crash.

The producer creates products, consumers take the first available product.

To show that the process instances are persisted,

1) deploy the process with 'ant deploy'
2) create 3 products with 'ant launch-producer' (launch the command 3 times)
3) consume 1 product with 'ant launch-consumer'
4) stop tomcat ('ant stop' on the root directory of orchestra installation)
5) restart tomcat ('ant start' on the root directory of orchestra installation)
6) consume the 2 remaining products with 'ant launch-consumer'
