"No MimeMessage content" exception when sending SimpleMailMessage

Question

I'm trying to send a very simple email with org.springframework.mail.javamail.JavaMailSenderImpl. Below is the code :

SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setTo(request.getCustomerEmail());
mailMessage.setSubject("someSubject");
mailMessage.setFrom("[email protected]");
mailSender.send(mailMessage);

This is the exception I get :

Caused by: org.springframework.mail.MailSendException: Failed messages: javax.mail.MessagingException: No MimeMessage content
at org.springframework.mail.javamail.JavaMailSenderImpl.doSend(JavaMailSenderImpl.java:459)
at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:307)
at org.springframework.mail.javamail.JavaMailSenderImpl.send(JavaMailSenderImpl.java:296)

I really don't understand why this happens..

Any idea ?

Answer 1

After a couple of hours of struggling, I've found that this is all because the mail I'm creating has no text !

If I add this line, then it works like a charm :

mailMessage.setText("blabla");

I really got confused by the "No MimeMessage content" message.. Does anybody agree that the message could be more informative, or is it only me ? Does this mean we can't send an email with just a subject and no content ?
