Send eMail and attachement from any SMTP server using JavaMail in Oracle ADF

The JavaMail API provides a platform-independent and protocol-independent framework to build mail and messaging applications- JavaMail API

This post is about sending eMail and attachments from any SMTP (Simple Mail Transfer Protocol) as Gmail or any other server (mail.awasthiashish.com)
You can read my previous post about mail integration with ADF that was specifically about using Gmail Server
Gmail Integration with Oracle ADF using Java Mail API 

So all basic configuration is described in previous post , now in this post i am only writing a java method to send mail and attachments


Don't forget to download these 2 jar files

  1.mail.jar 2. Activation.jar- Download

Add both jar files to project library path and then use this method 

Necessary packages to import -

import java.util.ArrayList;
import java.util.Properties;

import javax.activation.DataHandler;
import javax.activation.DataSource;

import javax.activation.FileDataSource;

import javax.mail.BodyPart;
import javax.mail.Message;
import javax.mail.MessagingException;
import javax.mail.Multipart;
import javax.mail.NoSuchProviderException;
import javax.mail.PasswordAuthentication;
import javax.mail.Session;
import javax.mail.Transport;
import javax.mail.internet.AddressException;
import javax.mail.internet.InternetAddress;
import javax.mail.internet.MimeBodyPart;
import javax.mail.internet.MimeMessage;
import javax.mail.internet.MimeMultipart;

Helper method (JavaCode) to send simple eMail and eMail with attachment-

    /**Method to send mail from any SMTP server using JavaMail API
     * Provide Correct Parameters
     * @return
     * @param msg- Email Message Body
     * @parsm subject- Subject of Email

     * @param pwd- Password of sender's email address
     * @param hostName- Host Name of Mail server (smtp.gmail.com)
     * @param isAnyAtchmnt- "Y" for yes there is an attachement and "N" for no attachment
     * @param fileNamePath- abolute path of file on server if there is any attachement

Call this method in your ADF Application to send simple mail or mail with attachment, this is just like plug n play , provide correct parameters and use

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
ADF.
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]));
}

emailMessage.setSubject(emailSubject);

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

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();
messageBodyPart1.setText(emailBody);

//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));
messageBodyPart2.setFileName(filename);


//5) create Multipart object and add MimeBodyPart objects to this object
Multipart multipart = new MimeMultipart();
multipart.addBodyPart(messageBodyPart1);
multipart.addBodyPart(messageBodyPart2);

//6) set the multiplart object to the message object
emailMessage.setContent(multipart);

• 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 = "smtp.gmail.com";
String fromUser = emailId; //just the id alone without @gmail.com
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());
transport.close();
StringBuilder msgEmail = new StringBuilder("Email Sent");
FacesMessage msg = new FacesMessage(msgEmail.toString());
msg.setSeverity(FacesMessage.SEVERITY_INFO);
FacesContext.getCurrentInstance().addMessage("No Network Error !", msg);
System.out.println("Email sent successfully.");
} catch (MessagingException e) {
System.out.println("somthing went wrong-->Messaging Exception");

}

}
