Java EE (Java Enterprise Edition) General Discussion

Hi All,

i am using SimpleMailMessage to send mail. This is working properly. Now i need to send attachment.

For that i am trying to implement
JavaMailSenderImpl sender = new JavaMailSenderImpl();
sender.setHost("mail.host.com ");
MimeMessage message1 = sender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(message1, true);
helper.setFrom("hai.com");
helper.setSentDate(Calendar.getInstance().getTime());
helper.setSubject(subject);
helper.setText("Hi");
helper.addAttachment("txn.pdf", pdfLocation);
helper.setTo(mailTo);
sender.send(message1);

when i execute this code i got this error
