How to attach a PDF in a mail using Java Mail?

Attaching a PDF to an email in Java can be done using the JavaMail API. To send an email with attachments, you need to create a MimeMessage and use a MimeBodyPart for the main message body and another MimeBodyPart for the attachment. Both are then combined in a MimeMultipart.

Here is an example that demonstrates how to send an email with a PDF attachment using JavaMail:

Setup and Dependencies

First, ensure you have the necessary libraries. If you're using Maven, add the JavaMail dependency in your pom.xml:

<dependency> <groupId>com.sun.mail</groupId> <artifactId>javax.mail</artifactId> <version>1.6.2</version> <!-- Or a more recent version --> </dependency>

Code to Send Email with PDF Attachment

Now, let's create a Java class that sends an email with a PDF attachment.

import javax.mail.*; import javax.mail.internet.*; import javax.activation.*; import java.util.Properties; import java.io.File; public class EmailWithPdfAttachment { public static void main(String[] args) { // Email configuration final String smtpHost = "smtp.yourprovider.com"; // SMTP server final int smtpPort = 587; // SMTP port, adjust as necessary final String fromEmail = "youremail@domain.com"; final String fromPassword = "yourpassword"; final String toEmail = "recipient@domain.com"; // PDF file to attach File pdfFile = new File("path/to/your/file.pdf"); // Set up properties for the SMTP connection Properties props = new Properties(); props.put("mail.smtp.host", smtpHost); props.put("mail.smtp.port", smtpPort); props.put("mail.smtp.auth", "true"); props.put("mail.smtp.starttls.enable", "true"); // Enable TLS if needed // Create a session with the provided properties Session session = Session.getInstance(props, new Authenticator() { @Override protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(fromEmail, fromPassword); } }); try { // Create a new email message Message message = new MimeMessage(session); message.setFrom(new InternetAddress(fromEmail)); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(toEmail)); message.setSubject("Subject of the Email with PDF Attachment"); // Create the email body part MimeBodyPart textPart = new MimeBodyPart(); textPart.setText("This is the body of the email."); // Create the attachment part MimeBodyPart attachmentPart = new MimeBodyPart(); DataSource source = new FileDataSource(pdfFile); attachmentPart.setDataHandler(new DataHandler(source)); attachmentPart.setFileName(pdfFile.getName()); // Combine body and attachment into a multipart MimeMultipart multipart = new MimeMultipart(); multipart.addBodyPart(textPart); multipart.addBodyPart(attachmentPart); // Set the multipart content to the message message.setContent(multipart); // Send the email Transport.send(message); System.out.println("Email sent successfully with PDF attachment."); } catch (MessagingException e) { e.printStackTrace(); } } }

Explanation

  • Email Configuration: Set the SMTP host, port, sender's email, password, and recipient's email.
  • File to Attach: Specify the PDF file to attach.
  • SMTP Properties: Configure properties for the SMTP server (like host, port, authentication, and TLS).
  • Session Creation: Create a Session with SMTP properties and authentication.
  • Email Components:
    • MimeMessage: The email message itself.
    • MimeBodyPart: The text part and the attachment part.
    • MimeMultipart: Combines body and attachment(s).
  • Sending the Email: Use Transport.send() to send the email with the MimeMultipart content.
  • Error Handling: Include a try-catch block to handle MessagingException and other exceptions.

With this code, you can send an email with a PDF attachment in Java using JavaMail. Ensure that your SMTP server settings are correct, and you have the necessary permissions to send emails via your chosen server.
