import javax.servlet.http.*;

public final class MailExample extends HttpServlet
{

public void doGet(HttpServletRequest request,HttpServletResponse response)
   throws ServletException, IOException
   {
      /* Output */
      response.setContentType("text/html");
      PrintWriter out = response.getWriter();

out.println("<html><body>\n");

/* Send message and catch exceptions */
      try {
         sendMessage("mail.owta.net","chris@owta.net","chris@owta.net","hello world","hello");
         out.println("Message sent");
      } catch(AddressException ae){
         out.println("Bad address");
      } catch(SendFailedException sf){
         out.println("Failed to send message");
      } catch(MessagingException mexc){
         out.println("Failed to send message");
      }
      out.println("</body></html>\n");

}
   public static void sendMessage(String Host, String FromAddress, String ToAddress, String Subject, String Body)
   throws AddressException, SendFailedException, MessagingException
   {
      Properties p = System.getProperties();
      p.put("mail.host", Host);

MimeMessage message = new MimeMessage(Session.getInstance(p, null));
      message.setFrom(new InternetAddress(FromAddress));
      message.setRecipients(Message.RecipientType.TO,
      InternetAddress.parse(ToAddress));
      message.setSubject(Subject);
      message.setText(Body);

Transport.send(message);
