Can someone please look at my jsp code here that sends an e-mail. Sometimes it works. Sometimes it doesn't and output EOF on socket error:
javax.mail.AuthenticationFailedException: EOF on socket




Properties props = new Properties();

props.put("mail.smtp.host", "mysmtp");

Session s = Session.getInstance(props,null);


Store store = s.getStore("pop3");

store.connect(mypop3, username, password);


MimeMessage message = new MimeMessage(s);


InternetAddress from = new InternetAddress("myemail");

message.setFrom(from);

String toAddress = request.getParameter("to");

InternetAddress to = new InternetAddress(toAddress);

message.addRecipient(Message.RecipientType.TO, to);


String subject = request.getParameter("subject");

message.setSubject(subject);

String text = request.getParameter("text");

message.setText(text);


Transport.send(message);

store.close();


Can someone tell me whats wrong with it?
I cannot use the getTransport function because it produce error when compiled on jsp as javax.servlet don't support that method. So I have to use the Store method to verify my username and password. A million thanks.
