* "text" content type, or byte arrays otherwise.</li>
|

* <li>For other request types, the request body will be used as the payload
|
||||
* and the type will depend on the Content-Type header value. If it begins with
|
||||
* "text", a String will be created. If the Content-Type is
|
||||
* "application/x-java-serialized-object", the request body will be expected to

* contain a Serializable Object, and that will be used as the message payload.
|

* Otherwise, the payload will be a byte array.</li>

* a response will be generated. If a {@link #setView(View) view} has been

* default of "requestMessage"). If no view is provided, and the 'expectReply'
|

* value is <code>false</code> then a simple OK status response will be issued.

* <p/>
|

* To handle request-reply scenarios, set the 'expectReply' flag to

* <code>true</code>. By default, the reply Message's payload will be

* extracted prior to generating a response. The payload must be either

* <p/>
|
||||
* In the request-reply case, if a 'view' is provided, the response will
|
||||
* not be generated directly from the reply Message or its extracted payload.
|
||||
* Instead, the model map will be passed to that view, and it will contain
|
||||
* either the reply Message or payload depending on the value of
|
||||
* {@link #extractReplyPayload}. The corresponding key in the map will be
|
||||
* determined by the {@link #replyKey} property (with a default of "reply").
|
