Can't send mail with gwt

Yo!

I have a problem with sending mail when using GWT. I have tested the code I've written without using GWT which works fine, but when it is in a GWT project it doesn't send any mails at all.

I run the the method on the server side in GreetingServiceImpl. And can see that the mail runs when I press a button, but nothing seems to be sent. No network traffic goes out when trying to call the sendMail method either.
I'm using eclipse. What can be wrong?

code for method sendMail(String subject, String message, String from, String[] recipients, byte[] attachment)

boolean debug = false;

//Set the host smtp address
Properties props = new Properties();
props.setProperty("mail.transport.protocol", "smtp");
props.setProperty("mail.smtp.port", "25");
props.setProperty("mail.host", "x.x.x.x");
props.setProperty("mail.from", from);
props.setProperty("mail.smtp.auth", "false");

// create some properties and get the default Session
Session session = Session.getDefaultInstance(props, null);
session.setDebug(debug);
// create a message
Message msg = new MimeMessage(session);
// set the from and to address
try {
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/plain");
Transport.send(msg);
}
catch (NullPointerException e) { e.printStackTrace(); }
catch (AddressException e) { e.printStackTrace(); }
catch (MessagingException e) { e.printStackTrace(); }

Be nice!

Welcome to the Ranch.

Are you using GAE along with GWT? If yes, GAE, in development mode, does not send out actual emails, but just prints it to the log

Yep! unmark appengine did the trick. You have been very kind! Thank you!
