/**
 * 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.
 *
 * Several other samples are provided as JUnit test-cases:
 *
 * <ul>
 *     <li>TcpClientServerDemoWithConversionServiceTest</li>
 *     <li>TcpServerConnectionDeserializeTest</li>
 *     <li>TcpServerCustomSerializerTest</li>
