I am doing a sendMail Servlet with JavaMail. I have javax.mail.AuthenticationFailedException on my output. Can anyone please help me out? Thanks.
sendMailServlet code:
try {
String host = "smtp.gmail.com";
String from = "[email protected]";
String pass = "pass";
Properties props = System.getProperties();
props.put("mail.smtp.starttls.enable", "true");
props.put("mail.smtp.host", host);
props.put("mail.smtp.user", from);
props.put("mail.smtp.password", pass);
props.put("mail.smtp.port", "587");
props.put("mail.smtp.auth", "true");
props.put("mail.debug", "true");
Session session = Session.getDefaultInstance(props, null);
MimeMessage message = new MimeMessage(session);
Address fromAddress = new InternetAddress(from);
Address toAddress = new InternetAddress("[email protected]");
message.setFrom(fromAddress);
message.setRecipient(Message.RecipientType.TO, toAddress);
message.setSubject("Testing JavaMail");
message.setText("Welcome to JavaMail");
Transport transport = session.getTransport("smtp");
transport.connect(host, from, pass);
message.saveChanges();
Transport.send(message);
transport.close();
}catch(Exception ex){
out.println("<html><head></head><body>");
out.println("ERROR: " + ex);
out.println("</body></html>");
}
Output on GlassFish 2.1:

You need to implement a custom Authenticator
import javax.mail.Authenticator;
import javax.mail.PasswordAuthentication;
class GMailAuthenticator extends Authenticator {
String user;
String pw;
public GMailAuthenticator (String username, String password)
{
super();
this.user = username;
this.pw = password;
}
public PasswordAuthentication getPasswordAuthentication()
{
return new PasswordAuthentication(user, pw);
}
}
Now use it in the Session
Session session = Session.getInstance(props, new GMailAuthenticator(username, password));
