Sending mail attachment using Java
Solution 1
Working code, I have used Java Mail 1.4.7 jar
import java.util.Properties;
import javax.activation.*;
import javax.mail.*;
public class MailProjectClass {
public static void main(String[] args) {
final String username = "[email protected]";
final String password = "your.password";
Properties props = new Properties();
props.put("mail.smtp.auth", true);
props.put("mail.smtp.starttls.enable", true);
props.put("mail.smtp.host", "smtp.gmail.com");
props.put("mail.smtp.port", "587");
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
Message message = new MimeMessage(session);
message.setFrom(new InternetAddress("[email protected]"));
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse("[email protected]"));
message.setSubject("Testing Subject");
message.setText("PFA");
MimeBodyPart messageBodyPart = new MimeBodyPart();
Multipart multipart = new MimeMultipart();
String file = "path of file to be attached";
String fileName = "attachmentName";
DataSource source = new FileDataSource(file);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(fileName);
multipart.addBodyPart(messageBodyPart);
message.setContent(multipart);
System.out.println("Sending");
Transport.send(message);
System.out.println("Done");
} catch (MessagingException e) {
e.printStackTrace();
}
}
}

For an unknow reason, the accepted answer partially works when I send email to my gmail address. I have the attachement but not the text of the email.
If you want both attachment and text try this based on the accepted answer :
Properties props = new java.util.Properties();
props.put("mail.smtp.host", "yourHost");
props.put("mail.smtp.port", "yourHostPort");
props.put("mail.smtp.auth", "true");
props.put("mail.smtp.starttls.enable", "true");
// Session session = Session.getDefaultInstance(props, null);
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication("user", "password");
}
});
Message msg = new MimeMessage(session);
try {
msg.setFrom(new InternetAddress(mailFrom));
msg.setRecipient(Message.RecipientType.TO, new InternetAddress(mailTo));
msg.setSubject("your subject");
Multipart multipart = new MimeMultipart();
MimeBodyPart textBodyPart = new MimeBodyPart();
textBodyPart.setText("your text");
MimeBodyPart attachmentBodyPart= new MimeBodyPart();
DataSource source = new FileDataSource(attachementPath); // ex : "C:\\test.pdf"
attachmentBodyPart.setDataHandler(new DataHandler(source));
attachmentBodyPart.setFileName(fileName); // ex : "test.pdf"
multipart.addBodyPart(textBodyPart); // add the text part
multipart.addBodyPart(attachmentBodyPart); // add the attachement part
msg.setContent(multipart);
Transport.send(msg);
} catch (MessagingException e) {
LOGGER.log(Level.SEVERE,"Error while sending email",e);
}
Update :
If you want to send a mail as an html content formated you have to do
MimeBodyPart textBodyPart = new MimeBodyPart();
textBodyPart.setContent(content, "text/html");
So basically setText
is for raw text and will be well display on every server email including gmail, setContent
is more for an html template and if you content is formatted as html it will maybe also works in gmail

Using Spring Framework , you can add many attachments :
package com.mkyong.common;
import javax.mail.MessagingException;
import javax.mail.internet.MimeMessage;
import org.springframework.core.io.FileSystemResource;
import org.springframework.mail.MailParseException;
import org.springframework.mail.SimpleMailMessage;
import org.springframework.mail.javamail.JavaMailSender;
import org.springframework.mail.javamail.MimeMessageHelper;
public class MailMail
{
private JavaMailSender mailSender;
private SimpleMailMessage simpleMailMessage;
public void setSimpleMailMessage(SimpleMailMessage simpleMailMessage) {
this.simpleMailMessage = simpleMailMessage;
}
public void setMailSender(JavaMailSender mailSender) {
this.mailSender = mailSender;
}
public void sendMail(String dear, String content) {
MimeMessage message = mailSender.createMimeMessage();
try{
MimeMessageHelper helper = new MimeMessageHelper(message, true);
helper.setFrom(simpleMailMessage.getFrom());
helper.setTo(simpleMailMessage.getTo());
helper.setSubject(simpleMailMessage.getSubject());
helper.setText(String.format(
simpleMailMessage.getText(), dear, content));
FileSystemResource file = new FileSystemResource("/home/abdennour/Documents/cv.pdf");
helper.addAttachment(file.getFilename(), file);
}catch (MessagingException e) {
throw new MailParseException(e);
}
mailSender.send(message);
}
}

This worked for me.
Here I assume my attachment is of a PDF
type format.
Comments are made to understand it clearly.
public class MailAttachmentTester {
public static void main(String[] args) {
// Recipient's email ID needs to be mentioned.
String to = "[email protected]";
// Sender's email ID needs to be mentioned
String from = "[email protected]";
final String username = "[email protected]";//change accordingly
final String password = "test";//change accordingly
// Assuming you are sending email through relay.jangosmtp.net
Properties props = new Properties();
props.put("mail.smtp.host", "smtp.gmail.com");
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");
// Get the Session object.
Session session = Session.getInstance(props,
new javax.mail.Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
return new PasswordAuthentication(username, password);
}
});
try {
// Create a default MimeMessage object.
Message message = new MimeMessage(session);
// Set From: header field of the header.
message.setFrom(new InternetAddress(from));
// Set To: header field of the header.
message.setRecipients(Message.RecipientType.TO,
InternetAddress.parse(to));
// Set Subject: header field
message.setSubject("Attachment");
// Create the message part
BodyPart messageBodyPart = new MimeBodyPart();
// Now set the actual message
messageBodyPart.setText("Please find the attachment below");
// Create a multipar message
Multipart multipart = new MimeMultipart();
// Set text message part
multipart.addBodyPart(messageBodyPart);
// Part two is attachment
messageBodyPart = new MimeBodyPart();
String filename = "D:/test.PDF";
DataSource source = new FileDataSource(filename);
messageBodyPart.setDataHandler(new DataHandler(source));
messageBodyPart.setFileName(filename);
multipart.addBodyPart(messageBodyPart);
// Send the complete message parts
message.setContent(multipart);
// Send message
Transport.send(message);
System.out.println("Email Sent Successfully !!");
} catch (MessagingException e) {
throw new RuntimeException(e);
}
}
}

I am trying to send an email using Java and Gmail. I have stored my files on the cloud and the stored files I want to send as an attachment to my email.
It should add those files to this mail and not links of those files.
How I can send such attachments?
-
Larry Lo over 10 yearsit raise connection timeout exception

Ronak Joshi over 9 yearsI have used your class,but it gives error like this, " 530 5.7.0 Must issue a STARTTLS command first. pa5sm839428pdb.28 - gsmtp " @NINCOMPOOP
-
AllTooSir over 9 yearsTry adding this:
props.put("mail.smtp.EnableSSL.enable","true");

Rahil Kumar over 8 years@NINCOMPOOP : I am getting Below Exception javax.mail.SendFailedException: Sending failed; nested exception is: class javax.mail.MessagingException: Could not connect to SMTP host: smtp.gmail.com, port: 587; nested exception is: java.net.ConnectException: Connection timed out: connect at javax.mail.Transport.send0(Transport.java:218) at javax.mail.Transport.send(Transport.java:80) at sendMail.SendMail4.execute(SendMail4.java:70) at sendMail.sel.main(sel.java:10)

snowmanjack about 7 yearsThis modification worked for me. I was getting the attachment correctly, but not getting any email body text. With the code exactly as @amdev has, I got email with body text and the attachment. Thanks!
-
roz over 6 yearsagree with above comment, this should be the accepted answer!
-
TroniPM almost 6 yearsIt should be like
String file = "./folder1/folder2/file.txt";
andString fileName = "newFileNameOnSMPTServer.txt";
. -
danciplus over 5 yearsNot to mislead: this modification attend only the additional attachments. It is clear necessary to have also the insertion of additional attachments. I put the above code in a separate bean and the Client interface in a jsp file like ""<input name="myfile" type="file"><p> <input name="myfile2" type="file"><p> <input name="myfile3" type="file"><p> <input name="myfile4" type="file"><p>> ""

aran about 4 yearsworking still 7 years and a pandemic later, thanks a lot

SJuan76 over 3 yearsIt seems that message.setContent(multipart) just removes (as it is implied) all the content set by message.setText. Please correct the answer.
