Solve error javax.mail.AuthenticationFailedException

Solve error javax.mail.AuthenticationFailedException

I'm not familiar with this function to send mail in java.I'm getting an
error while sending email to reset password. Hope you can give me a help.
Thanks in advance.

Below is code in SendMail :
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;
}
}
In my showlog error throws :
