I'm not familiar with this function to send mail in java. I'm getting an error while sending email to reset a password. Hope you can give me a solution.
Below is my code:
public synchronized static boolean sendMailAdvance(String emailTo, String subject, String body)
{
String host = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-ADDRESS");
String userName = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-USERNAME");
String password = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-PASSWORD");
String port = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-PORT");
String starttls = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-STARTTLS");
String socketFactoryClass = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-SOCKET-CLASS");
String fallback = AppConfigManager.getProperty("SENDER-EMAIL-SMTP-ALLOW-FALLBACK");
try
{
java.util.Properties props = null;
props = System.getProperties();
props.put("mail.smtp.user", userName);
props.put("mail.smtp.host", host);
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.debug", "true");
if(!"".equals(port))
{
props.put("mail.smtp.port", port);
props.put("mail.smtp.socketFactory.port", port);
}
if(!"".equals(starttls))
props.put("mail.smtp.starttls.enable",starttls);
if(!"".equals(socketFactoryClass))
props.put("mail.smtp.socketFactory.class",socketFactoryClass);
if(!"".equals(fallback))
props.put("mail.smtp.socketFactory.fallback", fallback);
Session session = Session.getDefaultInstance(props, null);
session.setDebug(true);
MimeMessage msg = new MimeMessage(session);
msg.setFrom(new InternetAddress(userName));
msg.setSubject(subject);
msg.setText(body, "ISO-8859-1");
msg.setSentDate(new Date());
msg.setHeader("content-Type", "text/html;charset=\"ISO-8859-1\"");
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(emailTo));
msg.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(host, userName, password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
return true;
}
catch (Exception mex)
{
mex.printStackTrace();
return false;
}
}
Throws the following error:

Most of AuthenticationFieldException Error occur when sign-in attempted prevented, login your gmail first and go to https://www.google.com/settings/security/lesssecureapps and check turn on. I solved this kind of problem like this way.
May be this problem cause by Gmail account protection. Just click below link and disable security settings.It will work. https://www.google.com/settings/security/lesssecureapps
I had this issue as well but the solution had nothing to do with coding. Make sure you are able to connect to gmail. Ping smtp.gmail.com. If you don't get a reply check your firewall settings. It could also be a proxy setting issue.
The solution that works for me has two steps.
First step

Enable the gmail security
https://myaccount.google.com/u/2/lesssecureapps?pli=1&pageId=none
If you are logging in to your gmail account from a new application or device, Google might be blocking that device. Try following these steps:
To protect your account, Google might make it harder to sign in to your account if we suspect it isn’t you. For example, Google might ask for additional information besides your username and password if you are traveling or if you try to sign in to your account from a new device.
Go to https://g.co/allowaccess from a different device you have previously used to access your Google account and follow the instructions. Try signing in again from the blocked app.
Change this (set less secure app): https://www.google.com/settings/security/lesssecureapps
Just in case anyone comes looking a solution for this problem.
The Authentication problems can be alleviated by activating the google 2-step verification for the account in use and creating an app specific password. I had the same problem as the OP. Enabling 2-step worked.
There are a few steps you have to keep in mind.
Now there are two scenarios If you are developing it in your local machine login to your google account in your browser, this way the google recognizes the machine.
If you have deployed the application onto a server then after the first request you will get an authentication error, so you have to give access to the server, just go here to give access- https://www.google.com/accounts/DisplayUnlockCaptcha

By default Gmail account is highly secured. When we use gmail smtp from non gmail tool, email is blocked. To test in our local environment, make your gmail account less secure as
I have been getting the same error for long time.
When i changed session debug to true
Session session = Session.getDefaultInstance(props, new GMailAuthenticator("[email protected]", "xxxxx"));
session.setDebug(true);
I got help url https://support.google.com/mail/answer/78754 from console along with javax.mail.AuthenticationFailedException.
From the steps in the link, I followed each steps. When I changed my password with mix of letters, numbers, and symbols to be my surprise the email was generated without authentication exception.
Note: My old password was more less secure.

You got your gmail smtp setting wrong. Gmail requires SSL. Please see tutorials on how to send email via Java via Gmail SMTP, eg: http://www.mkyong.com/java/javamail-api-sending-email-via-gmail-smtp-example/
