    <p>This program attempts to send e-mail but throws a run time exception:</p> <pre><code>javax.mail.AuthenticationFailedException: failed to connect, no password specified? </code></pre> <p>Why am I getting this exception when I have supplied the correct username and password for authentication?</p> <p>Both the sender and receiver have g-mail accounts. The sender and the receiver both have g-mail accounts. The sender has 2-step verification process disabled. </p> <p>This is the code:</p> <pre><code>import javax.mail.*; import javax.mail.internet.*; import java.util.*; class tester { public static void main(String args[]) { Properties props = new Properties(); props.put("mail.smtp.host" , "smtp.gmail.com"); props.put("mail.stmp.user" , "username"); //To use TLS props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); props.put("mail.smtp.password", "password"); //To use SSL props.put("mail.smtp.socketFactory.port", "465"); props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.port", "465"); Session session = Session.getDefaultInstance( props , null); String to = "me@gmail.com"; String from = "from@gmail.com"; String subject = "Testing..."; Message msg = new MimeMessage(session); try { msg.setFrom(new InternetAddress(from)); msg.setRecipient(Message.RecipientType.TO, new InternetAddress(to)); msg.setSubject(subject); msg.setText("Working fine..!"); Transport transport = session.getTransport("smtp"); transport.connect("smtp.gmail.com" , 465 , "username", "password"); transport.send(msg); System.out.println("fine!!"); } catch(Exception exc) { System.out.println(exc); } } } </code></pre> <p>Even after giving the password I get the exception. Why is it not authenticating?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
