Java Bean 发邮件实例，本例源码将利用J2EE 提供的java Mail 功能。与一个邮件服务器的会话由Session 对象封装。Session 对象可以用于获取Store 服务（例如POP 或者IMAP 服务器）和消息Transport 服务的句柄。电子邮件消息是由Message 对象封装的，同时通过使用一个具体的MimiMessage 对象在Internet 上封装电子邮件消息。-Java Bean mail instance, in this case the source will use java Mail feature J2EE provides. And a mail server session by the Session object encapsulation. Session object can be used to get a handle Store service (such as POP or IMAP server) and Message Transport services.
