JavaMail问题.
小弟才学JSP,看到JavaMail一部份.照着例子运行但是出错提示:
553 xxxxx@21.com: Sender address rejected: not logged in
书上例子是雅虎的,我改为我自己的21cn.com邮箱.
Properties props = new Properties();
props.put( "mail.smtp.host ", "smtp.21cn.com ");
Session s = Session.getInstance(props);
MimeMessage message = new MimeMessage(s);
InternetAddress from = new InternetAddress( "xxxxx@21.com ");
message.setFrom(from);
InternetAddress to = new InternetAddress( "xxxxx@21.com ");
message.addRecipient(Message.RecipientType.TO, to);
message.setSubject( "Test from JavaMail. ");
message.setText( "Hello from JavaMail. ");
Store store = s.getStore( "pop3 ");
store.connect( "pop.21cn.com ", "xxxxx ", "xxxxxxxxxx ");
Transport.send(message);
store.close();
以上那里有问题吗?21cn.com应该是提供客户端程序收发邮件的啊.
[解决办法]
提供邮箱的用户名和密码。

newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(to));
newMessage.setSubject(subject);
newMessage.setSentDate(new Date());
newMessage.setText(content);
//给消息对象设置内容
BodyPart mdp=new MimeBodyPart();//新建一个存放信件内容的BodyPart对象
mdp.setContent(content, "text/html;charset=gb2312 ");//给BodyPart对象设置内容和格式/编码方式
Multipart mm=new MimeMultipart();//新建一个MimeMultipart对象用来存放BodyPart对象(事实上可以存放多个)
mm.addBodyPart(mdp);//将BodyPart加入到MimeMultipart对象中(可以加入多个BodyPart)
newMessage.setContent(mm);//把mm作为消息对象的内容
newMessage.saveChanges();
transport = sendMailSession.getTransport( "smtp ");
transport.send(newMessage);
