Hi,
The following code snippet, sends an email from a person's GMail
account to itself.
public static void sendSampleMail(final String username, final String
password) throws MessagingException {
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.debug", "true");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.port", "465");
props.put("mail.smtp.socketFactory.port", "465");
props.put("mail.smtp.socketFactory.class",
"javax.net.ssl.SSLSocketFactory");
props.put("mail.smtp.socketFactory.fallback", "false");
Session session = Session.getDefaultInstance(props, new
Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
InternetAddress userAddress = new InternetAddress(username);
Message message = new MimeMessage(session);
message.setFrom(userAddress);
message.addRecipient(Message.RecipientType.TO, userAddress);
message.setSubject("JavaMail/GMail test");
message.setContent("This is a message from you to yourself
:-)", "text/plain");
Transport.send(message);
}
Just enter "yourUsername_at_gmail.com" as the username, and your password
as the password and you can verify that it works...
Now I wanted to create a JavaMail Session Resource in Glassfish
preconfigured with these properties and use it to send an email from
my test Web application. You can see a screen shot of the JavaMail
Session's setup at:
http://files.myopera.com/behrangsa/files/glassfish_mail_1.JPG
http://files.myopera.com/behrangsa/files/glassfish_mail_2.JPG
Here's the code that I use to lookup the JavaMail session and use it
to perform the same action:
Context c = new InitialContext();
Session session = (Session) c.lookup("java:comp/env/mail/gmail");
session.setPasswordAuthentication(session.getTransport().getURLName(),
new PasswordAuthentication("x_at_gmail.com", "pass"));
InternetAddress userAddress = new InternetAddress("x_at_gmail.com");
Message message = new MimeMessage(session);
message.setFrom(userAddress);
message.addRecipient(Message.RecipientType.TO, userAddress);
message.setSubject("JavaMail/GMail test");
message.setContent("This is a message from you to yourself
:-)", "text/plain");
Transport.send(message);
When I run the above code, I get the following exception:
javax.servlet.ServletException:
com.sun.mail.smtp.SMTPSendFailedException: 530 5.7.0 Must issue a
STARTTLS command first 15sm7996698wrl
The problem is that the returned Session object is not populated with
the properties I have defined via the Admin GUI. This can be confirmed
by enumerating the Session's properties:
Properties p = sess.getProperties();
Enumeration e = p.propertyNames();
while (e.hasMoreElements()) {
String elem = (String) e.nextElement();
out.print("<p>" + elem + " --- " + p.getProperty(elem) + "</p>");
}
Which returns:
mail.from --- behrangsa_at_gmail.com
mail.debug --- false
mail.transport.protocol --- smtp
mail.user --- behrangsa_at_gmail.com
mail.imap.class --- com.sun.mail.imap.IMAPStore
mail.host --- smtp.gmail.com
mail.store.protocol --- imap
mail.smtp.class --- com.sun.mail.smtp.SMTPTransport
Any ideas why the JavaMail session is not populated with the
configuration properties I have defined via the Admin GUI?
A suggestion:
I think it would be better, instead of having the required "Mail Host"
field, to have two (probably required) fields, named "Outgoing Mail
Server" and "Incoming Mail Server", because it is common to have two
different mail servers one for outgoing mails (e.g. smtp.gmail.com)
and one for incoming mails (e.g. pop3.gmail.com).
Thanks in advance,
Behi
