 }
}

*****************************
如果要添加附件 參考下面程序片段  把下面的程序片段添加到①
   String attachment = "c:\1.txt";//附件

  if (!attachment.equals("")) {

   BodyPart messageBodyPart = new MimeBodyPart();
   messageBodyPart.setText(new String(content.getBytes("ISO8859_1"),
     "GBK")); //

   Multipart multipart = new MimeMultipart();
   multipart.addBodyPart(messageBodyPart); //

   messageBodyPart = new MimeBodyPart();//

   DataSource source = new FileDataSource(attachment);

   messageBodyPart.setDataHandler(new DataHandler(source));

   messageBodyPart.setFileName(attachment);

   multipart.addBodyPart(messageBodyPart);

   message.setContent(multipart);
  }

最后要記得在tomcat的lib目錄下添加mail.jar,j2ee.jar,activation.jar。
