我写了这个index.jsp代码，用于使用Gmail为另一个人发送邮件。但它不起作用，并给我这个错误。

试试这个代码，
final String username = "[email protected]";
final String password = "xxxxx";
Properties props = new Properties();
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
然后创建一个会话
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
然后发送你的电子邮件，
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
message.setSubject(subject);
message.setText(messageText);
Transport.send(message);
