Class MessageFactory

java.lang.Object
  org.jboss.soa.esb.message.format.MessageFactory

public abstract class MessageFactory
extends java.lang.Object

You get a message of a specific type when you need it. Obviously that type may not be suitable for the service (hopefully you've got that contractual information a priori, but maybe not) and in which case some translation/transformation may be necessary. Different ways of viewing and manipulating the Message Body (payload) are available separately via the Payload class. In future releases it will be possible to define the payload type at creation time.
