Gmail Integration with Oracle ADF using Java Mail API

Gmail is a free secure webmail provided by google, can be accessed by using POP3 or IMAP4 protocol
we have option to integrate Gmail with Java using Java Mail API and I have tried same in Oracle
I have developed an application that can send mail (with Attachements) using Gmail in Oracle ADF,
using bounded TaskFlow.

  • First , in bounded taskflow ,a login page is created, and a page to send mail is created
  • Now you can get values from page and use in bean- So I am not going to write these things
  • Integration points starts when you get mail server properties- Managed Bean Code
  • You have to use 2 JAR ,inorder to use Java Mail API
  1.mail.jar 2. Activation.jar- Download
    Properties emailProperties;

    public void setMailServerProperties() {
    String emailPort = "587"; //gmail's smtp port
    emailProperties = System.getProperties();
    emailProperties.put("mail.smtp.port", emailPort);
    emailProperties.put("mail.smtp.auth", "true");
    emailProperties.put("mail.smtp.starttls.enable", "true");


  • Now you have to create your message (With or Without attachments)--

  • public void createEmailMessageWidtAtchmnt() throws AddressException, MessagingException {
    toWhom = toBind.getValue().toString();
    subject = subjectBind.getValue().toString();
    messagae = messageBind.getValue().toString();
    String[] toEmails = { toWhom };

    String emailSubject = subject;
    String emailBody = messagae;

    mailSession = Session.getDefaultInstance(emailProperties, null);
    emailMessage = new MimeMessage(mailSession);

    for (int i = 0; i < toEmails.length; i++) {
    emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmails[i]));


    //1) create MimeBodyPart object and set your message content
    BodyPart messageBodyPart1 = new MimeBodyPart();

    emailMessage.setContent(emailBody, "text/html"); //for a html email

  • here I am getting values from page component binding so don't get confused by this- toBind
    subjectBind, messageBind are component binding of page

  • Code snippet to create mail with attachements, you have to do little change in createEmailMessageWidtAtchmnt() to add files in mail . This code browse files from D drive
    of system .

  • //1) create MimeBodyPart object and set your message content
    BodyPart messageBodyPart1 = new MimeBodyPart();

    //2) create new MimeBodyPart object and set DataHandler object to this object
    MimeBodyPart messageBodyPart2 = new MimeBodyPart();

    String filename = "D://" + file_name; //change accordingly
    System.out.println("Exact path--->" + filename);
    DataSource source = new FileDataSource(filename);
    messageBodyPart2.setDataHandler(new DataHandler(source));

    //5) create Multipart object and add MimeBodyPart objects to this object
    Multipart multipart = new MimeMultipart();

    //6) set the multiplart object to the message object
  • To add files in mail in ADF you have to use af:inputFile component, and create a ValueChangeListener on component that get fileName when you browse any file from D drive of your system .

  • private String file_name;

    public void uploadedFileAttachmentVCE(ValueChangeEvent valueChangeEvent) {
    UploadedFile file = (UploadedFile)valueChangeEvent.getNewValue();
    file_name = file.getFilename();
  • From login page you will get login emailId and password, that is set in managed bean code to authenticate user- and send mail

  • public void sendEmail() {

    String emailHost = "";
    String fromUser = emailId; //just the id alone without
    String fromUserEmailPassword = pwd;
    Transport transport = null;
    try {
    transport = mailSession.getTransport("smtp");
    } catch (NoSuchProviderException e) {
    System.out.println("No such Provider Exception");
    try {
    transport.connect(emailHost, fromUser, fromUserEmailPassword);
    transport.sendMessage(emailMessage, emailMessage.getAllRecipients());
    StringBuilder msgEmail = new StringBuilder("Email Sent");
    FacesMessage msg = new FacesMessage(msgEmail.toString());
    FacesContext.getCurrentInstance().addMessage("No Network Error !", msg);
    System.out.println("Email sent successfully.");
    } catch (MessagingException e) {
    System.out.println("somthing went wrong-->Messaging Exception");
