/**
 * This example deploys a simple Stateless Session Bean that is used as a proxy to send and receive
 * JMS messages in a managed environment.
 *
 * Since this example is also used by the smoke test, it is essential that the VM exits with exit
 * code 0 in case of successful execution and a non-zero value on failure.
