Object Message context in which to set the SOAP message.

A message context contains properties for the SOAP message and provides access to the SOAP message. Integration Server creates the message context and passes it to the header handler. All handlers invoked by a given instance of a SOAP request or SOAP response use the same message context, which enables you to use the message context to pass information among handlers.

Object of type javax.xml.soap.SOAPMessage to use to overwrite the existing SOAP message in the message context.
