How to solve the exception "java.lang.NoClassDefFoundError: com/sun/mail/util/MailLogger". I am trying to send email through selenium webdriver

Question

Here is my code for sending email

Properties props = new Properties();
            props.put("mail.smtp.host", "smtp.abc.com");
            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,
                    new javax.mail.Authenticator() {
                        protected PasswordAuthentication getPasswordAuthentication() {
                            return new PasswordAuthentication("vijaya.teke@abc.com", "********");
                        }

                    });

            try {

                Message message = new MimeMessage(session);
                message.setFrom(new InternetAddress("vijaya.teke@abc.com"));
                message.setRecipients(Message.RecipientType.TO,InternetAddress.parse("vijaya.teke@abc.com"));
                message.setSubject("Testing Subject");
                BodyPart messageBodyPart1 = new MimeBodyPart();
                messageBodyPart1.setText("This is message body");
                MimeBodyPart messageBodyPart2 = new MimeBodyPart();
                String filename = "D:\\Automation\\Automation workspace\\TestSelenium\\Screenshots";
                DataSource source = new FileDataSource(filename);
                messageBodyPart2.setDataHandler(new DataHandler(source));
                messageBodyPart2.setFileName(filename);
                Multipart multipart = new MimeMultipart();
                multipart.addBodyPart(messageBodyPart2);
                multipart.addBodyPart(messageBodyPart1);
                message.setContent(multipart);
                Transport.send(message);
                System.out.println("=====Email Sent=====");

            } catch (MessagingException e) {

                throw new RuntimeException(e);
            }

I am getting error "java.lang.NoClassDefFoundError: com/sun/mail/util/MailLogger" at the line "Session session = Session.getDefaultInstance(props," line. I am not getting the solution. Please help me.

Remove some code which is not relevant for you . like zip calling functions etc
