Sending email using Java Mail API
In this tutorial we will see how to send email using Java Mail API. We are using Gmail SMTP host for sending email in the below sample code.
Mainly we need 2 jar files to implement Java Mail API. Those jar's are
- activation-1.0.2.jar
- mail-1.4.1.jar
Below code have tested along with above jar files.
import java.util.Properties; import javax.mail.Message; import javax.mail.MessagingException; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.AddressException; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; public class SendEmailViaGmail { public static void main(String[] args) { // To address String to = "to@gmail.com"; // If any CC email ids String cc = "cc@abcmail.com"; // If any BCC email ids String bcc = "bcc@abcmail.com"; // Email Subject String subject = "Java Discover"; // Email content String emailText = "Hi All, Welcome to Java Discover"; // Sending Email using Gmail SMTP sendEmail(to, cc, bcc, subject, emailText); } public static void sendEmail(String to, String cc, String bcc, String subject, String emailText) { // From address (Need Gmail ID) String from = "from@gmail.com"; // Password of from address String password = "frompassword"; // Gmail host address String host = "smtp.gmail.com"; Properties props = System.getProperties(); props.put("mail.smtp.host", host); 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"); props.put("mail.smtp.user", from); props.put("password", password); Session session = Session.getDefaultInstance(props, null); MimeMessage msg = new MimeMessage(session); try { msg.setFrom(new InternetAddress(from)); // Adding To address msg.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to, false)); // Adding CC email id msg.setRecipients(Message.RecipientType.CC, InternetAddress.parse(cc, false)); // Adding BCC email id msg.setRecipients(Message.RecipientType.BCC, InternetAddress.parse(bcc, false)); msg.setSubject(subject); msg.setText(emailText); Transport transport = session.getTransport("smtp"); transport.connect(host, from, password); transport.sendMessage(msg, msg.getAllRecipients()); transport.close(); System.out.println("Email sent successfully....."); } catch (AddressException e) { e.printStackTrace(); } catch (MessagingException e) { e.printStackTrace(); } } }
IMP:
Suppose if you are getting exception while running above like,
javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
then valid SSL certificate is missing in the machine which your running. Follow the steps given in link and try again.
