In message mode , a Dispatch object
works with complete messages. A complete message includes any binding specific headers and
wrappers. For example, a consumer interacting with a service that requires SOAP messages
would need to provide the Dispatch object's invoke() method a
fully specified SOAP message. The invoke() method will also return a fully
specified SOAP message. The consumer code is responsible for completing and reading the SOAP
message's headers and the SOAP message's envelope information.
Note: Message mode is not ideal when you wish to work with JAXB objects.
You specify that a Dispatch object uses message mode by providing the
value java.xml.ws.Service.Mode.MESSAGE when creating the Dispatch object.
