Examples of org.jboss.soa.esb.message.Message

org.jboss.soa.esb.message.Message
This is the basic internal core message abstraction. A message consists of the following components: Header: the header information contains information such as the destination EPR, the sender EPR, where the reply goes etc, i.e., general message-level functional information. Context: additional information to contextualise the message; for example, transaction or security data, the identity of the ultimate receiver, or HTTP-cookie like information. Body: the actual payload of the message. Fault: any fault information associated with the message. Attachment: any attachments associated with the message. Properties: any message specific properties. Each message, once created, has a corresponding element for these 5 components. That element may be empty (NOT NULL). The object representing the element can then be used to act on the corresponding data item in the message. @author Mark Little
