I use Amazon SES service to send email in tomcat6. It can only send email success for several hours and then it will send email failed. If I reboot the tomcat6, it will send email success again for several hours and then failed. This problem has been bothering me for a several days.
Does any body has encountered this problem? please help me, thanks.
//Send email code:
public class MyAuthenticator extends Authenticator {
String userName = null;
String password = null;
public MyAuthenticator() {
}
public MyAuthenticator(String username, String password) {
this.userName = username;
this.password = password;
}
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(userName, password);
}
}
//send email
public class SimpleMailSender {
public final static String HOST = "email-smtp.us-east-1.amazonaws.com";
public final static int PORT = 25;
public final static String FROM_ADDRESS = "[email protected]";
public final static String TO_ADDRESS = "[email protected]";
public final static String USER = "xx";
public final static String PASSWORD = "xxx";
public static void sendTestEmail()
{
try
{
Properties p = new Properties();
p.put("mail.transport.protocol", "smtp");
p.put("mail.smtp.host", HOST);
p.put("mail.smtp.port", PORT);
p.put("mail.smtp.auth", "true");
p.put("mail.smtp.starttls.enable", "true");
p.put("mail.smtp.starttls.required", "true");
p.put("mail.debug", "true");
MyAuthenticator authenticator = new MyAuthenticator(USER, PASSWORD);
Session sendMailSession = Session.getDefaultInstance(p, authenticator);
Message mailMessage = new MimeMessage(sendMailSession);
Address from = new InternetAddress(FROM_ADDRESS);
mailMessage.setFrom(from);
Address to = new InternetAddress(TO_ADDRESS);
mailMessage.setRecipient(Message.RecipientType.TO, to);
mailMessage.setSubject("Test");
mailMessage.setSentDate(new Date());
Multipart mainPart = new MimeMultipart();
BodyPart html = new MimeBodyPart();
html.setContent("Test", "text/html; charset=utf-8");
mainPart.addBodyPart(html);
mailMessage.setContent(mainPart);
Transport.send(mailMessage);
}catch(Exception ex)
{
ex.printStackTrace();
}
}
}
