/**
* The @Message annotation marks a SimpleBamService method as handling

*
* <code><pre>

* </pre></code>
*
* A ping error message handler would look like:
*
* <code><pre>
* @Message
* public void pingMessage(String to, String from, MyPing value)
* {
* System.out.println("Ping: " + value
* + " {to:" + to + ", from:" + from + "}");
