高分求javamail程序能通过smtp认证的。

[xinxing]

我写的发送邮件程序只能在163成功，到smtp.yeah.net就总是不行，后来才直到这些网站需要认证，然后在程序中又加入了自定义的Authenticator类，还是不行，试了N次，虽然“失败是成功他妈”，但怕是“失败他妈等不到他爸就吐血身亡了”，所以向诸位求助！给个成功的例子！不胜感激，未能高分以报！

jia you!

“失败他妈等不到他爸就吐血身亡了”
----
此话有误，应该是“失败等不到（成功）他爸就吐血身亡了”

javahui(阶级斗争要年年讲，月月讲，天天讲。) ：我的和你的差不多呀，还是不行，再帮我一把！
tibetty(laoduan)老兄：指点得有道理！有理想就帮我看看我的程序到底哪里不行？总显示“邮件发送失败！javax.mail.AuthenticationFailedException”。

为什么要用什么Authenticator的类

我不太明白你到底要干嘛

[javahui]

你的构造函数：
public sendMail(String smtp){
setSmtpHost(smtp);
createMimeMessage();
}

createMimeMessage();方法执行中
mimeMsg = new MimeMessage(session); //创建MIME邮件对象

session是null。当然会失败了。

兄弟，下面是我在一个商务网站的一段代码看一下吧
try
{
Properties props = new Properties();
props = new Properties();
props.put("mail.smtp.host", mail_smtp_host);
props.setProperty("mail.transport.protocol","smtp");
props.setProperty("mail.smtp.auth","true");
Session s = Session.getInstance(props, null);

MimeMessage message = new MimeMessage(s);

InternetAddress from = new InternetAddress(mail_from);
message.setFrom(from);
InternetAddress to = new InternetAddress(email);
message.addRecipient(Message.RecipientType.TO,to);
message.setSubject(subject);

MimeBodyPart messageBodyPart =new MimeBodyPart();
//设置邮件内容，构建程序段如下：
messageBodyPart.setText(content);

Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);

Transport transport = s.getTransport("smtp"); //注意是smtp服务器
transport.connect(mail_smtp_host,mail_account_username,mail_account_password);
transport.sendMessage(message,message.getAllRecipients());
transport.close();
}
catch(Exception e)
{
//out.print("<br><br><div align = center>现在不能发送邮件,请稍后再发送！</div>");
}

另外要在一个头文件中写：
//[.:邮箱参数设置:.]
String mail_smtp_host = "smtp.163.net"; //发邮件的主机
String mail_account_username = ""; //邮箱帐号名
String mail_account_password = ""; //邮箱密码
String mail_from = "[e-mail]"; //邮箱地址

嗯..不错耶...马上就要用到javamail了///

是在weblogic中配了mail session
