public class Message

extends MessagePart

This class describes the structure of a message content for delivering. The Message class defines the interface for applications to represent complex message content, which is MIME type based and potentially multipart. The main content of a message is actually described in MessagePart, the Message class encapsulates a few message-wide properties.
The message can be extended to represent customized message format.It implements the Externalizable interface so that it can be serialized fast. It can be stored in the database persistently as a Java object. No information will be lost even if it is an extended one. Instances of the Messages object potentially can be persisted after externalization depending on how the system routes the message.
