Hey,
Im currently having problems with the code below:
public class SendMail {
     private static final String SMTP_HOST_NAME = "smtp.gmail.com";
     private static final String SMTP_AUTH_USER = "[email protected]";
     private static final String SMTP_AUTH_PWD = "**************";
     public void sendMail(String recipients[ ], String subject, String message , String from) throws MessagingException{
     boolean debug = false;
          Properties props = System.getProperties();
          props.put("mail.transport.protocol", "smtp");
          props.put("mail.smtp.host", SMTP_HOST_NAME);
          props.put("mail.smtp.port", "465");
          props.put("mail.smtp.starttls.enable", "true");
          props.put("mail.smtp.auth", "true");
          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);
     msg.setSubject(subject);
     msg.setContent(message, "text/plain");
     Transport tr = session.getTransport("smtp");
     tr.connect(SMTP_HOST_NAME, SMTP_AUTH_USER, SMTP_AUTH_PWD);
     msg.saveChanges(); // don't forget this
     //tr.sendMessage(msg, msg.getAllRecipients());
     tr.close();
     tr.send(msg);
     public class SMTPAuthenticator extends Authenticator
     public PasswordAuthentication getPasswordAuthentication()
     String username = SMTP_AUTH_USER;
     String password = SMTP_AUTH_PWD;
     return new PasswordAuthentication(username, password);
the error i am receiving is:
java.lang.NoClassDefFoundError: javax/mail/Authenticator
