The MailReaderBean used in the Reading tab is exactly the same as the one shown in Pro-
gram: MailReaderBean .

The MailComposeBean used for the Sending tab is a GUI component for composing a mail
message. It uses the Mailer class from Mail-Enabling a Server Program to do the actual
sending. Example 17-11 shows the MailComposeBean program.

public public class class MailComposeBean MailComposeBean extends extends JPanel {
