Java EE (Java Enterprise Edition) General Discussion

I am trying to send mail through my server. I am just writing a simple program but unable to send. I am using javax.mail - 1.5.0.jar. Below is the code:

import java.util.Properties;

import javax.mail.Message;

import javax.mail.MessagingException;

import javax.mail.PasswordAuthentication;

import javax.mail.Session;

import javax.mail.Transport;

import javax.mail.internet.InternetAddress;

import javax.mail.internet.MimeMessage;

public class SendMailTLS {

  public static void main(String[] args) {

  final String username = "*****@***.com";

  final String password = "*****";

  final String to = "*****@***.com";

  Properties props = new Properties();

  props.put("mail.smtp.auth", "true");

  props.put("mail.smtp.starttls.enable", "true");

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

  props.put("mail.smtp.port", "***");

  System.out.println("After putting properties");

  Session session = Session.getInstance(props,

  new javax.mail.Authenticator() {

  protected PasswordAuthentication getPasswordAuthentication() {

  return new PasswordAuthentication(username, password);

  }

  });

  try {

  System.out.println("In try block");

  Message message = new MimeMessage(session);

  message.setFrom(new InternetAddress(username));

  message.setRecipients(Message.RecipientType.TO,

  InternetAddress.parse(to));

  message.setSubject("Testing Subject");

  message.setText("Dear Mail Crawler,"

  + "\n\n No spam to my email, please!");

  Transport.send(message);

  System.out.println("Done");

  } catch (MessagingException e) {

  throw new RuntimeException(e);

  }

  }

}

After running this I am getting following exception:

Exception in thread "main" java.lang.RuntimeException: javax.mail.MessagingException: Could not connect to SMTP host: *******, port: ***, response: -1

  at SendMailTLS.main(SendMailTLS.java:50)

PLEASE HELP ME IN SOLVING THIS....
