Java EE (Java Enterprise Edition) General Discussion

I am using gmail account and I use thunderbird to download all the emails and to compose my emails. Now I'm trying to write a java application that will send out emails. Since I'm still in school I am using gmail account for the class project.

One t hing I noticed is that in my thunderbird I use secure connection using TLS. How should I incorporate that here in the java code. Is that why I'm getting the exception. Anyone knows any other smtp server using which I could submit my assignment.

Here is my code:

package com.imagework.email;

import java.util.Properties;

import javax.mail.Authenticator;
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 SendMailUsingAuthentication {

	private static final String SMTP_HOST_NAME = "smpt.gmail.com";
	private static final String SMTP_PORT = "587";	
	private static final String SMTP_AUTH_USER = "roger.rustin1@gmail.com";
	private static final String SMTP_AUTH_PWD = "abcde";
	private static final String emailMsgTxt = "email message text";
	private static final String emailSubjectTxt = "email subject";
	private static final String emailFromAddress = "roger.rustin1@gmail.com";

	// Add List of Email address to who email needs to be sent to separated by comma
	private static final String[] emailList = { "roger.rustin2@gmail.com" };

	public static void main(String args[]) throws Exception {
		SendMailUsingAuthentication smtpMailSender = new SendMailUsingAuthentication();
		smtpMailSender.postMail(emailList, emailSubjectTxt, emailMsgTxt,
				emailFromAddress);
		System.out.println("Sucessfully Sent mail to All Users");
	}

	public void postMail(String recipients[], String subject, String message,
			String from) throws MessagingException {
		boolean debug = true;

		Properties props = new Properties();
		props.put("mail.smtp.host", SMTP_HOST_NAME);
		props.put("mail.smtp.auth", "true");
		props.put("mail.debug", "true");
		props.put("mail.smtp.user", SMTP_AUTH_USER);
		props.put("mail.smtp.password", SMTP_AUTH_PWD);		
		props.put("mail.smtp.port", SMTP_PORT );

		Authenticator auth = new SMTPAuthenticator();
		Session session = Session.getDefaultInstance(props, auth);

		session.setDebug(debug);

		Message msg = new MimeMessage(session);

		InternetAddress addressFrom = new InternetAddress(from);
		msg.setFrom(addressFrom);

		InternetAddress[] addressTo = new InternetAddress[recipients.length];
		for (int i = 0; i < recipients.length; i++) {
			addressTo[i] = new InternetAddress(recipients);

		}

		msg.setRecipients(Message.RecipientType.TO, addressTo);



		// Setting the Subject and Content Type

		msg.setSubject(subject);

		msg.setContent(message, "text/plain");

		

//		Transport trans = session.getTransport();

//		trans.connect(SMTP_HOST_NAME, SMTP_PORT , SMTP_AUTH_USER, SMTP_AUTH_PWD);

//		trans.send(msg);

		

		Transport.send(msg);

	}



	/**

	* SimpleAuthenticator is used to do simple authentication when the SMTP

	* server requires it.

	*/

	private class SMTPAuthenticator extends javax.mail.Authenticator {



		public PasswordAuthentication getPasswordAuthentication() {

			String username = SMTP_AUTH_USER;

			String password = SMTP_AUTH_PWD;

			return new PasswordAuthentication(username, password);

		}

	}

}



The error I get is given in detail:
