We will see a very simple program to send the email in JAVA using JAVAMail API. Please download all the jar files and include in the library.
Code to send email :
import javax.mail.*; import javax.mail.internet.*; import java.util.*; import java.io.*; public class SendMailUsingAuthentication { private static final String SMTP_HOST_NAME = "SMTP_HOST_NAME"; private static final String SMTP_PORT = "465"; private static final String SMTP_AUTH_USER = "SENDER_EMAIL"; private static final String SMTP_AUTH_PWD = "SENDER_PASS"; private static final String emailMsgTxt = "-----------Hello------------------ "; private static final String emailSubjectTxt = "Test Mail from JAVA"; private static final String emailFromAddress = "FROM_EMAIL"; // Add List of Email address to who email needs to be sent to private static final String[] emailList = { "TO_EMAIL_USER1","TO_EMAIL_USER2" }; public static void main(String args[]) throws Exception { SendMailUsingAuthentication mailSender = new SendMailUsingAuthentication(); mailSender.postMail(emailList, emailSubjectTxt, emailMsgTxt, emailFromAddress); System.out.println("Sucessfully Sent mail to All Users"); } public void postMail( String recipients[ ], String subject, String message , String from) throws MessagingException { boolean debug = false; //Set the host smtp address Properties props = new Properties(); props.put("mail.smtp.host", SMTP_HOST_NAME); props.put("mail.smtp.socketFactory.port", SMTP_PORT); //IF SSL required by Host props.put("mail.smtp.socketFactory.class" , "javax.net.ssl.SSLSocketFactory"); props.put("mail.smtp.auth", "true"); props.put("mail.debug", "true"); props.put("mail.smtp.port", SMTP_PORT); //Authenticate the Username and password for the SMTP Authenticator auth = new PasswordAuthentication(SMTP_AUTH_USER, SMTP_AUTH_PWD); Session session = Session.getDefaultInstance(props, auth); session.setDebug(debug); // create a message Message msg = new MimeMessage(session); // set the from and to address 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[i]); } msg.setRecipients(Message.RecipientType.TO, addressTo); // Setting the Subject and Content Type msg.setSubject(subject); msg.setContent(message, "text/plain"); System.out.println("Sending Email..........."); Transport.send(msg); System.out.println("Email Sent........."); } }
