How are you?"); Transport.send(msg); System.out.println("Sending message"); //does not get to this part } catch (MessagingException e) {…

Accepted Answer

I think you need to use 465 port, and smtps (Not smtp) for transport.

A complete workable code from an open source project :

http://jstock.hg.sourceforge.net/hgweb/jstock/jstock/file/d9290c44d19c/src/org/yccheok/jstock/alert/GoogleMail.java

```
/**
 * Send email using GMail SMTP server.
 *
 * @param username GMail username
 * @param password GMail password
 * @param recipientEmail TO recipient
 * @param ccEmail CC recipient. Can be empty if there is no CC recipient
 * @param title title of the message
 * @param message message to be sent
 * @throws AddressException if the email address parse failed
 * @throws MessagingException if the connection is dead or not in the connected state or if the message is not a MimeMessage
 */
public static void Send(final String username, final String password, String recipientEmail, String ccEmail, String title, String message) throws AddressException, MessagingException {
    Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
    final String SSL_FACTORY = "javax.net.ssl.SSLSocketFactory";

// Get a Properties object
    Properties props = System.getProperties();
    props.setProperty("mail.smtps.host", "smtp.gmail.com");
    props.setProperty("mail.smtp.socketFactory.class", SSL_FACTORY);
    props.setProperty("mail.smtp.socketFactory.fallback", "false");
    props.setProperty("mail.smtp.port", "465");
    props.setProperty("mail.smtp.socketFactory.port", "465");
    props.setProperty("mail.smtps.auth", "true");

/*
    If set to false, the QUIT command is sent and the connection is immediately closed. If set 
    to true (the default), causes the transport to wait for the response to the QUIT command.

    */
    props.put("mail.smtps.quitwait", "false");

Session session = Session.getInstance(props, null);

// -- Create a new message --
    final MimeMessage msg = new MimeMessage(session);

// -- Set the FROM and TO fields --
    msg.setFrom(new InternetAddress(username + "@gmail.com"));
    msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(recipientEmail, false));

if (ccEmail.length() > 0) {
        msg.setRecipients(Message.RecipientType.CC, InternetAddress.parse(ccEmail, false));
    }

msg.setSubject(title);
    msg.setText(message, "utf-8");
    msg.setSentDate(new Date());

SMTPTransport t = (SMTPTransport)session.getTransport("smtps");

t.connect("smtp.gmail.com", username, password);
    t.sendMessage(msg, msg.getAllRecipients());      
    t.close();
}
