Did you set the Properties correctly when you attempted to connect to smtp.gmail.com? You may need to add

The following works for me:

import java.util.Properties;
 
import javax.mail.Authenticator;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeMessage;
 
public class SendEmail {
 
    public static void sendEmail(String user, String pass, String from,
            String[] recipients, String subject, String message)
            throws MessagingException {
 
        // Set the host smtp address
        Properties props = new Properties();
        props.put("mail.smtp.starttls.enable", "true");
        props.put("mail.smtp.host", "smtp.gmail.com");
        props.put("mail.transport.protocol", "smtp");
        props.put("mail.smtp.auth", "true");
 
        Authenticator auth = new SMTPAuthenticator(user, pass);
        Session session = Session.getDefaultInstance(props, auth);
 
        session.setDebug(false);
 
        // create a message
        Message msg = new MimeMessage(session);
 
        // set the from and to address
        InternetAddress addressFrom = new InternetAddress(from);
        msg.setFrom(addressFrom);
 
        InternetAddress[] addressTo = new InternetAddress[recipients.length];
        for (int i = 0; i < recipients.length; i++) {
            addressTo[i] = new InternetAddress(recipients[i]);
        }
        msg.setRecipients(Message.RecipientType.TO, addressTo);
 
        // Setting the Subject and Content Type
        msg.setSubject(subject);
        msg.setContent(message, "text/html");
        Transport.send(msg);
    }
 
    /**
     * SimpleAuthenticator is used to do simple authentication when the SMTP
     * server requires it.
     */
    private static class SMTPAuthenticator extends javax.mail.Authenticator {
 
        private String username;
 
        private String password;
 
        public SMTPAuthenticator(String username, String password) {
            this.username = username;
            this.password = password;
        }
 
        public PasswordAuthentication getPasswordAuthentication() {
            return new PasswordAuthentication(username, password);
        }
    }
}
