你的代码工作。我复制它编译并使用我的gmail凭据运行它。你确定你使用正确的gmail凭证发送邮件吗？

MailHandler m = new MailHandler("[email protected]", "myPassword"); 
m.sendMail("Test", "Testing", "[email protected]", "[email protected]", "[email protected]");

//运行后，我检查了我的工作邮件，看到了邮件。

如果我使用无效的密码，我会得到以下的statcktrace。这就是你所看到

是的我得到这些错误 – ayushman999 2012-08-16 18:00:27

一个简单的解决方案是使用最后String参数，如 public void sendMail(final String username ,final String password);。
