/**
* Demonstrates the use of a gateway as an entry point into the integration flow.
* The message generated by the gateway is sent over tcp by the outbound gateway
* to the inbound gateway. In turn the inbound gateway sends the message to an
* echo service and the echoed response comes back over tcp and is returned to
* the test case for verification.
*
* The test uses explicit transformers to convert the byte array payloads to
* Strings.
