I tried sending an email with attached pdf-file using javax.mail maven dependency. The following code runs, but it doesnt finish Transport.send(message) line. There is no error, but program doesn't finist. I found out that it could take some time, but I waited over a minute and still nothing. I've looked at similar questions but the solutions have not worked.
public class EmailService { private String host = ""; private int port = 0; private String username = ""; private String password = ""; public EmailService(String host, int port, String username, String password) { this.host = host; this.port = port; this.username = username; this.password = password; sendMail(); } private void sendMail() { Properties prop = new Properties(); prop.put("mail.smtp.auth", true); prop.put("mail.smtp.starttls.enable", "true"); prop.put("mail.smtp.host", host); prop.put("mail.smtp.port", port); prop.put("mail.smtp.ssl.trust", host); Session session = Session.getInstance(prop, new Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }); try { Message message = new MimeMessage(session); message.setFrom(new InternetAddress("email@gmail.com")); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse("email@gmail.com")); message.setSubject("Mail Subject"); String msg = "This is my first email using JavaMailer"; MimeBodyPart mimeBodyPart = new MimeBodyPart(); mimeBodyPart.setContent(msg, "Email sent with java"); MimeBodyPart attachmentBodyPart = new MimeBodyPart(); attachmentBodyPart.attachFile(new File("file.pdf")); Multipart multipart = new MimeMultipart(); multipart.addBodyPart(mimeBodyPart); multipart.addBodyPart(attachmentBodyPart); message.setContent(multipart); Transport.send(message); System.out.println("Message sent"); } catch (Exception e) { e.printStackTrace(); } } public static void main(String ... args) { new EmailService("smtp.gmail.com", 25, "email@gmail.com", "password"); }}
