Object Message context from which to retrieve a property value.

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. For example, in a chain of request header handlers, the first request header handler could set a message property that the second request header handler retrieves.

String Name of the selected property whose value to retrieve.

Object Value of the specified property.
