javax.mail.Transport

[191085]

I've got that problem with email client. I used the class Transport and method send(), but it doesn't send any message. There is an error somewhere but I cannot figure out where. Here is a part of the code:

Message newMessage = new MimeMessage(session);
newMessage.setFrom(new InternetAddress(dialog.getFrom()));
newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(dialog.getTo()));
newMessage.setSubject(dialog.getSubject());
newMessage.setSentDate(new Date());
newMessage.setText(dialog.getContent());



//send the message

Transport.send(newMessage);
} catch (Exception e) {
showError("Message cannot be sent.", false);
}
}
I'm completely new to java since I mostly use c++, so any help will be appreciated.

- Are you sure your dialog.get*() methods are returning correct data ?

- How are you creating your session instance ? Are you adding the smpt host correctly ?

- Is there an exception thrown ? Its generally a good idea to print out the stack trace fully to give you an idea of what went wrong - try using :

e.printStackTrace(System.err);

Thank you, sedj. The session and methods are correct. Thanks to your advance I found the numbers of errors - one is 504 (authentification, so it's quite easy to solve once you know what it is) and the second - 554 (which I do not know what to do with; but at least I know what is wrong here).
