Encountering SMTPSendFailedException with SendMailServlet

[Michael K. Wilson]

Hello there,

Am trying to write a simple servlet which will send a sample e-mail through G-Mail...

BTW, I did follow the instructions posted on http://java.sun.com/products/javamail/FAQ.html#gmail.

Am using JDK 1.5.0, JavaMail 1.4, JAF 1.1.1 and when I deploy to my app server and click on:

http://localhost:8080/myapp/sendmail

SendMail.java:

public class SendMail extends HttpServlet
{
	static final long serialVersionUID = 1L;
	private static final String HOST = "smtp.gmail.com";
	private static final String USER = "myuser";
	private static final String PASSWORD = "password";
	private static final String fromEmailAddress = "[e-mail]";
 
	public SendMail()
	{
		super();
	}
 
	protected void doGet(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException
	{
		doPost(request, response);
 
	}
 
	protected void doPost(HttpServletRequest request,
			HttpServletResponse response) throws ServletException, IOException
	{
		PrintWriter out = response.getWriter();
		response.setContentType("text/html");
		boolean debug = false;
 
		// properties
		Properties props = new Properties();
		props.put("mail.transport.protocol", "smtp");
		props.put("mail.smtp.starttls.enable", "true");
		props.put("mail.smtp.host", HOST);
		props.put("mail.smtp.auth", "true");
 
		// ssl security providing
		java.security.Security
				.addProvider(new com.sun.net.ssl.internal.ssl.Provider());
 
		Authenticator auth = new SMTPAuthenticator();
		Session session = Session.getDefaultInstance(props, auth);
 
		String sendTo = "[e-mail]";
		String subject = "Welcome to JavaMail";
		String content = "JavaMail rocks!";
 
		session.setDebug(debug);
 
		// create a message
		Message message = new MimeMessage(session);
		Transport transport = null;
		try
		{
			transport = session.getTransport("smtps");
			try
			{
				// set the from and to address
				InternetAddress addressFrom = new InternetAddress(
						fromEmailAddress);
				message.setFrom(addressFrom);
 
				InternetAddress[] addressTo = new InternetAddress[] { new InternetAddress(
						sendTo) };
 
				message.setRecipients(Message.RecipientType.TO, addressTo);
 
				// Setting the Subject and Content Type
				message.setSubject(subject);
				message.setContent(content, "text/plain");
				transport.connect(HOST, USER, PASSWORD);
				transport.sendMessage(message, addressTo);
				// Transport.send(msg);
			}
			catch (Throwable t)
			{
				out.println("The message wasn't sent,some errors occured");
				t.printStackTrace();
			}
		}
		catch (NoSuchProviderException e)
		{
			e.printStackTrace();
		}
	}
 
	private class SMTPAuthenticator extends javax.mail.Authenticator
	{
		public PasswordAuthentication getPasswordAuthentication()
		{
			String username = USER;
			String password = PASSWORD;
			return new PasswordAuthentication(username, password);
		}
	}
}

Encountered the following exception:
