J'essaie d'envoyer des e-mails avec des images en ligne dans Google App Engine (Java). Voici mon code.Envoi d'e-mails avec des images en ligne dans Google App Engine (Java)
public void send(RecepientInfo[] toAddress, String subject, Attachment[] attachements) throws MessagingException, IOException {
